Avionics FAQ

Automatic Dependent Surveillance-Broadcast (ADS-B) is a component of the Next-Generation (Next Gen) Air Transportation System. ADS-B is an advanced surveillance technology that combines an aircraft's positioning source (GPS), aircraft avionics, and a ground infrastructure to create an accurate surveillance interface between the aircraft & aircraft traffic control. ADS-B provides consistent position accuracy regardless of the aircraft's range from the receiver.

The improved accuracy and update rate of ADS-B is a critical segment of the NextGen infrastructure.

The FAA has determined that it will be necessary for all aircraft operating in specific airspaces to be equipped with ADS-B Out by 2020. A nationwide infrastructure of ground stations is scheduled for completion during 2013.

As of June 2010, only ADS-B Out is being mandated. ADS-B Out provides the ATC with real-time position information. ADS-B In is the aircraft's ability to receive and display other aircraft broadcasted information as well as the services provided by the ground stations.

ADS-B requires the use of a Positioning Source. As of June 2010, any positioning source is allowed; however, WAAS is the only positioning service that provides the equivalent availability required.

A Broadcast Link is also required for ADS-B functionality. There are two available options: 1090 MHz Extended Squitter (ES) or Universal Access Transceiver (UAT). FL 180 (the lower boundary of Class A airspace) is the ceiling for operating an aircraft equipped with UAT only.

ADS-B will eventually provide weather services, air traffic information, terrain maps and other flight information services for all pilots through satellite based data and ground stations. In accordance with NextGen, ADS-B will provide benefits that address some shortcomings over other, existing surveillance systems.

Some of these benefits include:
  • Air-to-air surveillance capability
  • Surveillance in remote areas where radar coverage is unavailable
  • Real-time traffic information for aircraft not equipped with active traffic systems (ex. TCAS, TAS)
  • Reduced separation between aircraft due to sharing of flight information between aircraft
  • Better predictability in departure and arrival times

    Ultimately, ADS-B will allow aircraft to fly at safe distances from each another.

Extended Squitter (or 1090 ES) is the Mode S transport protocol for ADS-B operation. 1090 MHz extended squitter is an ADS-B link for air carrier, commercial, and private aircraft. With 1090ES, the Mode S transponder supports an extended squitter (ES) message. Currently, this message provides position, velocity, and heading information.

The ES versions of the Garmin GTX33, GTX-330, and GTX-330D transponders comply with FAA TSO C-166A which dictates the minimum performance standards (MPS) for 1090 MHz ADS-B equipment. Existing Garmin GTX Mode S transponders without ES can be upgraded through Garmin to include the Extended Squitter feature. On average the Extended Squitter option costs an additional $1000-$1500 USD.

It is very important to note that in order for the ES data to be broadcasted, the transponder must be interfaced to a compatible GPS that meets TSO C145a/C146a. These TSOs explains the performance standards for WAAS GPS receivers. As of 2009, the CNX80, GNS480, GNS400W/500W series and G1000 are the only Garmin GPS receivers that meet this criteria.
The following versions of the TRA-67A transponder are ADS-B compatible with Mode S extended squitter (also known as GPS squitter):

066-01127-1401
066-01127-1402
066-01127-1501
066-01127-1502
066-01127-1601
066-01127-1602
The word "squitter" refers to a random broadcast of data occurring usually in the absence of interrogation. As a component of the ADS-B system in the USA, Extended Squitter refers to a burst of extended data or message broadcasted on 1090 MHz. When connected to a GPS with the necessary integrity, a Mode S transponder with Extended Squitter capability will send a message providing position, velocity, and time.
Configuration and programming of the TT31 transponder is simple. Hold down the FUNC button while switching on the transponder and the setup system will run. The setup includes the following configurations items: Mode S Address, VFR Squawk Code, VFR Flight ID, Aircraft Maximum Airspeed, Aircraft Category, Squat switch source, if installed, GPS position source, if installed, ADS-B parameters, Audio Output Volume, LCD Dimming Settings.

All programming is performed using the right hand knob and the ENT, BACK, FUNC buttons.

No, the 2020 FAA ADS-B mandate only covers ADS-B "Out" for aircraft surveillance. ADS-B In features (traffic and weather) are optional.
As of 2011, there is no standard format for the display of the traffic and weather information that one can receive with a ADS-B receiver such as the 978 MHz UAT. Currently, manufacturers of 978 Mhz UATs and/or 1090 Mhz receivers are maintaining proprietary display formats for the traffic and weather received.
Yes, as of 2011, the FAA is requiring that you obtain a Supplemental Type Certificate for an ADS-B "Out" installation on any aircraft. Several OEMs and engineering companies such as Southeast Aerospace are developing STCs to be processed and eventually approved by the FAA. The FAA has not advised if future ADS-B installations will be possible through FAA STC AML (Approved Model List) although it is a good probability once several STCs have been issued.
The current Air Traffic Control (ATC) surveillance system in the United States is outdated and must be changed. Surveillance through GPS tracking is much more reliable and offers more widespread coverage than the current ground radar system. Therefore, the FAA has mandated that all aircraft must comply with the ADS-B Out mandate by 2020. If you do not comply and/or your aircraft is not capable of providing ADS-B output information, then you cannot fly in U.S. airspace after 2020.

Furthermore, ADS-B Out provides better aircraft tracking and surveillance thus ensuring a higher level of safety for all. For those who obtain and integrate ADS-B In systems into their aircraft, you will enjoy free weather and traffic information services via the ADS-B broadcast stations.
Considering the hundreds of ADS-B stations already installed and in use, years of research & development, and billions of tax dollars spent to implement ADS-B, the FAA has no plans to either change or cancel the ADS-B Out mandate.
No, technically a WAAS GPS is not the only GPS receiver that can be interfaced to a certified ADS-B Out system. Most WAAS GPS receivers provide all of the parameters and meet all of the performance requirements needed for an approved ADS-B Out system. Therefore, due to the popularity and availability of WAAS GPS receivers, most aircraft will be utilizing them in approved ADS-B systems.
If you fly above FL180, you must use a transponder capable of 1090ES (extended squitter) for ADS-B Out. If you fly internationally, you must use 1090ES as well. Therefore, you must continue to use a transponder in these applications. The 978 MHz UAT is only for use below FL180.
No, if you are currently operating an aircraft with one transponder antenna then the existing antenna configuration is acceptable for ADS-B Out compliance. The ADS-B Out mandate does not change any requirements for European Mode S antenna diversity or TCAS II antenna diversity in applicable aircraft.
  • Transmitter (ex. Transponder, UAT, etc.)
  • Position source (ex. WAAS GPS)
  • Altitude encoder
  • Air/Ground switch (ex. Squat switch)
  • GPS Antenna
  • Transponder antenna
While the TT21 is certified to TSO C166B, the TT21 is a Class 2 transponder and therefore does not meet the power output requirements for FAA transponder and ADS-B regulations. Currently, the FAA requirement for United States airspace is that ADS-B Out is in conjunction with a Class 1 transponder. Other ADS-B environments (ex. Europe and Australia) do not require a Class 1 transponder.

It is recommended that TT21 owners transition to the higher power, Class 1 TT22 to fully comply with the FAA ADS-B performance requirements.
No, the KT-73 does not meet ADS-B requirements. Previously, the KT-73 could be interfaced to the KMD-540 MFD for display of TIS traffic when operating an aircraft in area with TIS coverage. As of 2013, Bendix/King is working on a replacement for the KT-73 that will comply with the ADS-B mandate.
No, the KT-73 does not and will not meet any ADS-B requirements. There is no upgrade path from the KT-73 other than replacing the KT-73 with an ADS-B capable transponder such as the KT-74 or competing OEM product.
In relation to the transponder technology, a squawk refers to a response that a transmitter responder (i.e. transponder) is making to an interrogation from Air Traffic Control (ATC). In a classic Mode A/C transponder, a squawk response included very basic aircraft ID, general status, and pressure altitude information.

A squitter or squit is a transmission that frequently sends aircraft ID and position data while not being interrogated. In some Mode S transponders and ADS-B devices, the squit transmission can include up to almost 50 parameters including lat/long position, direction of flight, velocity, and more.
The KT-74 is a direct replacement only if ADS-B is not being utilized. The KT-74 is designed to fit into an existing KT-76A/C & KT-78A tray. However to utilize the ADS-B feature of the KT-74, a secondary connector and new tray will need to be installed.

The KT-74 has two Molex edge connectors. The primary connector can use the same contact positions and are electrically compatible with the KT-76A & KT-78A (if properly wired). A secondary connector would need to be installed to utilize ADS-B functions, resulting in a necessary second hole in the rack to accommodate the connector.

Audio Panel  -  Traffic alert audio output is interfaced to a required audio panel with a compatible unswitched, unmuted audio input


Altitude Source -The GDL-88 requires the use of an ownship pressure altitude for transmission of required ADS-B Out data values and to calculate the vertical separation and vertical closure from target aircraft.

 

TAS/TCAS Traffic Systems - The GDL-88 will interface with the GTS-800/820/850, Skywatch, Skywatch HP, and Avidyne TCAD.

 

Heading Source (optional) - The GDL-88 can optionally use heading for the purpose of correlating ADS-B traffic and traffic received from the external traffic system. HSDB and ARINC 429 digital heading is provided to the GDL 88 from any compatible magnetic heading source. Multiple heading sources may be connected to the GDL-88.

 

GPS Position Source - The GDL-88 uses the ownship GPS position for creation of the ADS-B Out messages as well as the receipt and tracking of ADS-B In targets. The GDL-88 without the internal GPS WAAS requires at least one compatible GPS position source be installed, while the GDL-88 with the internal GPS WAAS engine may optionally be interfaced with compatible sources.

 

Radar Altimeter (optional) - The GDL-88 can optionally be interfaced with a radar altimeter to drive the sensitivity level of the Conflict Situational Awareness (CSA) application.

 

Traffic Mute (optional) - The GDL-88 can optionally interface with a pilot controlled switch to acknowledge an active Conflict Situational Awareness (CSA) alert and mute the associated aural alert. This momentary switch only mutes the current CSAs and does not act as an inhibit for future CSA aural annunciations.

In a minimal installation, the GDL-88 provides the required ADS-B Out functionality with a standalone set of annunciators and control switches installed in the cockpit. When a GDL-88 is installed without interface to an external display, some ADS-B In functionality is still retained. A traffic annunciation light is installed in the cockpit for CSA (Conflict Situational Awareness) alerts and aural alerts are provided for these threat aircraft, to include directionality from the ownship and range.

While a GNS or GTN series product (with the proper software level) is what is most often used as a qualified position source, there are versions of the GDL-88 that include an internal WAAS receiver. Having a WAAS receiver is a requirement for ADS-B compliance. This will allow your exact position, speed, etc., to be broadcasted to other aircraft. Four versions of the GDL-88 are available:

GDL-88 Standard
GDL-88 with Diversity
GDL-88 with internal WAAS receiver
GDL-88 with Diversity and internal WAAS receiver

Yes, the GDL-88 is a dual transceiver, which means that it is capable of transmitting your ADS-B position. Most typical installations will be configured to be ADS-B out compliant, thereby satisfying the FAA's mandate. Your existing equipment and how the installation is performed may affect your ADS-B out capability.

Not necessarily, but operations within Class A, B, and C airspaces to include the airspaces above and below the B and C airspace including all airspace inside the Mode C ring. Additionally Class E 10,000 ft and above, or GOMEX operations 3,000 ft. and above will be required to equip. Furthermore, in order to receive the full Free benefits of the ADS-B IN you will need to become a valid client in the system to receive those benefits.

Many display manufactures have started to implement ADS-B inputs to display the FIS-B, and TIS-B products offered by the ADS-B system. Please verify with your display manufacturer if they can accept ADS-B information. For customers that either do not have a panel mounted display or chose to not use it for TIS-B/FIS-B products, the iPad with its many popular apps is also an option to view ADS-B products as well.

According to the FAA's Final Ruling, all aircraft operating in the designated airspace FL180 and above, would need to transmit ADS-B utilizing the 1090ES band. Aircraft that operate below FL180, have the option to equip with a 978 UAT solution or a 1090ES solution.

Yes, a portion of your ADS-B "out" transmission identifies which frequency receiver you have in the aircraft. Ground Stations will know which frequency to transmit the 'Re-broadcast' information to you. For example, if you are equipped with a UAT 978 MHz transceiver, then you will broadcast ADS- B data to the ground stations, part of which identify which receiver you have in the aircraft. With that information, the ground stations will re-broadcast back to you the area 1090ES ADS-B targets, as well as Legacy targets being sweeped by SSR (Secondary Surveillance Radar), assuming you are receiving all 978 (UAT) targets directly (Air-to-Air).

The traffic information you receive is dependent on a few variables, such as:

  • Your aircraft being a valid client into the ADS-B system

  • Your transmitter being properly configured to identify which band receiver you have installed

If you are not receiving a full traffic picture, then you may want to seek an experienced avoinics installer to verify proper installtaion, configuration, and ADS-B functionality.

When installed properly, transmitters have a method of pilots verifying if the transmitter has any critical messages or if there is a fault with the system. Pilots can also ask ATC if they are being reported as an ADS-B client.

FIS-B services are available in 100% of the Coverage Area up to FL240, and 90% of the coverage area up to FL400. The FL 180 threshold is only applicable to for ADS-B OUT.

The FreeFlight FDL-978 allows the flexibility to become ADS-B compliant and runs in conjunction with legacy transponders. However, even though ADS-B will become the FAA's primary source for surveillance, transponders will be required as a secondary (backup) surveillance source for the time being.

The FreeFlight FDL-978 will utilize L-Band antennas similar to your current transponder antenna. In very rare circumstances, a diplexer splitter can be installed to utilize a single antenna for a transponder and ADS- B Transmitter. It is highly recommended to install a dedicated antenna for ADS-B transmitters.

An approved ADS-B system does require high integrity GPS position source to be a valid ADS-B client. It is recommended to have at least a TSO-C145/146 GPS/WAAS position source. Please refer to AC20-165 (appendix 2) for position source requirements. FreeFlight Systems offer the 1201 and 1203C series GPS/ WAAS Sensors to supply position source options that fully meet the ADS-B requirements worldwide.

Honeywell has obtained STC# SA00765DE for the installation of the KT-74 for ADS-B Out functionality in a multitude of aircraft.  There is an Approved Model List that accompanies the STC.  Please see Resources for copies of the STC.

Yes, the RANGR Lite is meant for owner/operators who do not have an ES (Extended Squitter) upgradeable transponder or WAAS GPS in their aircraft. The less expensive unit (TXL) is Transmit only while the other (XVRL) includes ADS-B In as well which will display (traffic and weather) on the GNS-430 but would be need to be interfaced.

First, we would recommend contacting a local Garmin dealer to discuss the following:

  • Upgrading your existing nav/com to a used GNS-530W or the newer GTN-750.
  • If you already have a Garmin transponder (i.e. GTX-330), then you should simply get the ES upgrade, interface to GNS-530W or GTN-750, along with a few other minor installation considerations, and get the shop to do the appropriate paperwork based on Garmin's AML STC.
  • If you do not have the GTX-330, then you should just consider pursuing one of the GDL systems from Garmin. Most likely the GDL88 which will give you In/Out capability. Same interface and installation considerations as above apply. Please note ADS-B In is not required for the mandate.

UPDATE

5/9/2018

Bendix/King, L3 and ACSS released the NXT-700/MST-70B as form fit replacement for the MST-67A. It is DO-260B compliant to meet the ADS-B Out mandate.

There are other options besides the MST-70B to gain ADS-B compliance. There are various STCs that allow the removal of the Bendix/King transponder system and installation of Rockwell Collins or Garmin transponders. Upgrade prices vary depending on actual installed equipment. 

Regarding ADS-B for the Garmin GTX-330 transponders, the best solution is to simply have the units converted by Garmin to include the ES (Extended Squitter) upgrade. This upgrade is about $2000 approximately. Additionally, a WAAS/GPS source will need to be interfaced. We can process the upgrade for you or any other Garmin dealer can as well.

First, please reference the information Garmin provides in relation to the ES upgrade:

http://www.garmin.com/us/intheair/ads-b/seven-questions/

There is perhaps a misconception that simply having your Garmin GTX-330 transponder upgraded to include Extended Squitter capability is the only step for ADS-B Out compliance. As with almost all ADS-B installations, appropriate interfacing to other systems in the aircraft (ex. approved position source & altitude source) is required along with approved guidance material that indicates the airworthiness approval procedure followed for return to service of the aircraft (ex. AML STC). Garmin provides an Installation Manual with Approved Model List STC for its Aviation dealers. Authorized dealers should not be distributing the necessary data and paperwork for the ADS-B installation to non-dealers.

As with all ADS-B installations, Southeast Aerospace strongly recommends that you only contact and consult a trained, authorized avionics dealer.

No. Southeast Aerospace strongly recommends that you only contact and consult a trained, authorized avionics dealer for all ADS-B installations.

One of the reasons for much of the confusion, controversy, and misinformation surrounding ADS-B is due to those in the aviation realm who are minimalizing or ignoring key aspects of an ADS-B installation. Most if not all ADS-B installations are not a “box-swap” regardless of any advertising or information on the Internet stating as much. Even if you were to seek alternate, unauthorized methods to obtain ADS-B equipment or upgrades to existing equipment, you still need a way to get it in the aircraft and approved by the FAA. Most ADS-B product manufacturers only offer AML STCs they have to authorized dealers in their network.

If you want to be compliant and able to fly in 2020, then just get the job done right the first time. Unfortunately, some people in aviation always try to cut corners on avionics installations by underestimating the job at hand in hopes to save a buck. It never works out to your advantage no matter how it looks on the bottom line on the frontend of the job. The old saying holds true for ADS-B installations especially – “Pay Now or Pay Later”.

If you want your installation done right the first time legally and technically, then contact a trusted avionics shop that has formal training on ADS-B and the related products from the OEM. Or, contact the OEM and ask for a recommendation in your area. Most OEMs are more than happy to refer to a legitimate, quality dealer in your area.

Citation S550 equipped with: Transponders MST-67A 066-01143-2101. Chance to update to ES?

Garmin GPS400. Chance to update software to WAAS? Or maybe to replace with a GPS400W and link it with transponders? - FMS UNS-1L SCN 803.1. Citation Mustang C510 equipped with G1000 Integrated Flight Deck. It is a 2008 plane.

What can I do to get ADS-B at an affordable price?

A: Since the aircraft are operated in Spain, what region or ADS-B spec do you need to meet? (i.e. USA, DO-260B?)

Without knowing exactly what ADS-B requirement or mandate you might be trying to comply with, I can only provide information relative to what we know here in the USA in reference to ADS-B for Part 25 aircraft.

For the Citation 550, the MST-67A will be superseded by the MST-100B if/when Honeywell can produce and certify the MST-100B. I have attached the only details that we currently have on the MST-100B. Honeywell has not even released pricing on this unit yet, however, ideally it would be an ideal solution ultimately since it is said to be plug and play with the MST-67A. With a WAAS GPS interfaced it would meet all ADS-B mandates. Also, keep in mind, that your CAS-67 can be upgraded fairly easily to Change 7.1 via Honeywell sales bulletin upgrading the TPU-67A processor to the TPU-67B. There is a company that offers some STCs for Part 25 aircraft if your region requires an STC for the 7.1 upgrade - http://www.prostaraviation.com/

If the MST-100B does not pan out for some reason and/or Honeywell keeps delaying its release, then there is a company named Jettech that has released Garmin GTX 3000ES ADS-B capable transponder to its existing STC covering Garmin GTN install on Citation and Citation Jet aircraft equipped with TCAS II. In addition, the company amended its Garmin GTN autopilot coupled LPV FAA STC for the Citation 500 series to include all Primus 1000 equipped Bravo, Ultra, Encore and Excel aircraft. They do not have much information on their website about the ADS-B STC but I recently learned about it at the AEA convention last week - http://jettechllc.net/index.html

Regardless of what direction you might go in, you should most likely get your GPS-400 upgraded to the GPS-400W while Garmin is still offering the upgrade. It is relatively inexpensive at around $3000 USD. Most FANS type systems will require WAAS GPS input or accuracy ultimately. Plus, Garmin's WAAS interface tis very compatible with most ADS-B solutions. Regarding the Citation Mustang C510 equipped with G1000, Garmin is still working on this solution. We assume it will include the GTX-3000 transponder(s) as this aircraft will require a 1090 MHz, (not 978 MHz UAT) system. I would continue to monitor Garmin's website for announcements relating to the G1000.

In most cases, if you already have Garmin equipment, the easiest route to comply with ADS-B is to stay with Garmin. Based on what you gave me below, you would need to upgrade your GNS530 to the 530W (WAAS) and replace your GTX327 with the GTX330ES (Extended Squitter). Most shops will give you a trade-in value for the GTX327 and there are some used GTX330ES units out there on the market. This route will make you compliant with the 1090ES part of ADS-B compliance.

Otherwise, if you choose to keep the GTX327 and go with the GDL88 or GDL84 UAT (978 compliance), you will still have to get your GNS530 upgraded to WAAS and then handle some additional considerations.

Unfortunately, the GPS in the KMD-150 does not comply with any of the requirements for GPS performance in the latest ADS-B mandate or DO-260B. More or less, although it is not specifically referred as such, current WAAS GPS receivers are the only GPS receivers that meet the performance requirement needed for ADS-B Out.

Considering your current situation, here are a few possible scenarios for you to comply:

  1. Keep the KMD-150 with GPS as a stand-alone navigation aid and pursue the KGX-150 with internal GPS. This would of course require installing a separate WAAS GPS antenna on your aircraft for the KGX-150. In addition, you would not receive any of the ADS-B In benefits since the KMD-150 is not an interface for that. However, there are many options to display ADS-B In information on anything from smartphones, tablets, etc.
  2. Replace the KMD-150 with some sort of Garmin GNS or GTN navigator which will meet the approved position source requirements for ADS-B. I would recommend their GDL-84 or 88 boxes for the UAT portion of the equation however there are a few other manufacturers offering less expensive UAT solutions like Free Flight with their Ranger Lite product.


The second option is obviously going to be more expensive but gives you a little more versatility and more capability in your aircraft. I only included UAT (978) options because I am assuming that you are flying below 18,000 feet.

A few questions related to the KGX 150 :

  1. Can this unit be paired with the KT-76C transponder?
  2. What will the Wi-Fi option cost?
  3. With our configuration, what antennas will need to be installed to meet the ADSB-Out requirements?
  4. Will an additional antenna be required to facilitate ADS-B-In?

There are a few things to be aware of with all UAT installations. These units require a control device and a switch to place them in air/ground mode. The switch is not a major issue and is a minor cost. However, the controller is additional if the aircraft is not already equipped with a transponder and/or display (MX20 for example).

As you’ll see below, yes, the KT-76C will pair with the unit via the antennas. Basically the UAT will sense the XPDR. This will enable you to send the Mode A and IDENT information to the UAT unit. However, you are still required per the FAA to have a way to know your ADS-B status. If a suitable display such as the Garmin MX20, Aspen EFD1000 or the KSN 770 is not installed, then a remote control unit is required. The KGX Control Panel list price is currently $619. Depending on the aircraft and the kind of flying, there are a lot of factors and options to consider.

  1. Can this unit be paired with the KT-76C transponder?
    • Yes
  2. What will the Wi-Fi option cost?
    • The Wi-Fi option will run around $349 list for parts.
  3. With our configuration, what antennas will need to be installed to meet the ADS-B-Out requirements?
    • Per the STC, you will be required one external WAAS/GPS antenna and at least one UAT antenna.
  4. Will an additional antenna be required to facilitate ADS-B-In?
    • No, as long as the unit purchased is the transceiver. However, you will need a suitable display for the "In" without the Wi-Fi.

In regards to your RV-6A, upgrading to the GTX 330ES will take care of your 2020 requirements for ADS-B. As you already have a GTX 327 and a GNS 430W, you may be more pleased with the installation of a GDL 88 standard. The prices of the units are similar even once you add the new antenna for the GDL-88 (give or take about $150). The labor to install the GDL 88 will be more, but with the GDL 88 you will get free weather and traffic on the GNS 430W. This would then free up the Garmin 696 and the GDL 39 for your Luscombe.

In regards to your 1947 Luscombe 8-E, your options are not as straight forward. You have no WAAS/GPS receiver in the aircraft so one of the UAT units like the GDL 88/84 from Garmin, NGT-2500 from L-3, or the RANGR 978 from Freeflight will be your best option to give the ADS-B Out. The RANGR 978, with its control head (required per the installation manual), may be the least expensive option but all three will have a fair amount of labor for the installation.

Since SEA is a Rockwell Collins dealer, we can perform this modification. Some of the equipment for this modification can be sold in serviceable condition, but we cannot sell factory new without performing the upgrade ourselves. There are several components required to perform this modification as well as wiring changes and additions. We’re happy to discuss this modification in more detail with you and gather the information necessary to provide you with an accurate proposal.

Portable ADS-B Out systems, also known as "suitcase" units, should not be operated (transmitting) aboard any aircraft. While marketing associated with these units may imply approval for use by way of an FCC license, the FAA prohibits their use for the following reasons:

  1. The positioning of portable, suction-cup GPS antennas associated with these units often require they be affixed to front or side windows or glare shield to obtain a usable signal. Such antenna placement obstructs the pilot's view. Connecting wiring also interferes with aircraft controls and instruments.
  2. ADS-B Out avionics require a valid Mode S code to be transmitted to operate properly with ATC automation and other ADS-B aircraft. Mode S codes, also known as the ICAO code, are assigned to an aircraft during registration and then programmed into transponders and ADS-B Out avionics. Mode S codes remain static until a change in aircraft registration or identification (N-number) occurs. Portable units require users to input the Mode S code assigned to each aircraft flown. A high number of Mode S code entry errors have occurred with this procedure, which prevent proper target correlation within ATC automation systems (target drops/traffic conflict alerts), which have resulted in increased workload and unnecessary distractions for pilots and controllers.
  3. The positioning of ADS-B antenna is also vital in the quality of the signal that is transmitted, and if capable, received by the ADS-B device. There have been a number of aircraft identified using portable ADS-B devices that result in degraded performance due solely to poor antenna location.

The KLN-94 is not a WAAS GPS, nor is it upgradeable to one. We recommend the KT-74, but if you decide to upgrade to a GPS400W or GNS430W, then you would want to go with a GTX-330.

The FAA Rebate program has come to and end. Please reference the FAA's webite for more information. https://www.faa.gov/nextgen/equipadsb/rebate/faq/#q0201

Other discount opportunities include the following:

1. Fleet or multiple aircraft discounts. Many avionics shops will offer significant discounts for multiple aircraft ADS-B upgrade committments. 

2. Avionics vender sales bulletin special pricing. Avionics venders will, from time to time, come out with special pricing on specific equipment or equipment combinations. Sometimes the equipment pricing is tied to certain airframes. Avioncs shops often times pass these special pricing opportunites on to the customer. Special pricing bulletins always have an expiration date for equipment ordering and shipping so be mindful that pricing can change drastically if you do not commit. 

3. Avionics upgrades beyond ADS-B. When performing ADS-B upgrades along side of EFIS, Radio, or other upgrades discounts can be extended due to aircraft access and equipment bundle pricing. 

BendixKing announced a modification to the CitationJet CNI 5000 using the KT-74 transponder and a remotely mounted WAAS GPS receiver. A package including the hardware, modified bezel, and STC will be available to authorized dealers. Please contact Southeast Aerospace to discuss ADS-B and upgrade options for the CitationJet.  See photo below. Alternatively, there are existing STCs that allow the installation of Garmin GTN navigators in the CNI 5000 location. The GTN can then control remote mounted GTX 3X5R transponders for ADS-B Out and In. 

 

CNI 5000 ADS-B

 

There is no ADS-B In display option for a Honeywell MFRD. An iPad or other Flight Bag is the only option.

No, it is not economical to upgrade a -006 or lower. -007 and higher units should be pursued instead.

No, the GPS-4000 (PN 822-0931-XXX) cannot be upgraded to the GPS-4000S.  Only the GPS-4000 (PN 822-1377-001) can be upgraded to the GPS-4000S.

According to Collins' ADS-B Out Pricing Guide, it is not economical to upgrade a -006 or below TDR-94 or -94D. A replacement unit with a PN that meets ADS-B requirements should be installed.

The -501/-502/-551/-552 versions of the TDR-94/94D comply with DO-260B (V2) standard for ADS-B Out. The -501/-502 is applicable to fixed wing aircraft while the -551/-552 is applicable to rotary wing aircraft. Service bulletin upgrades and exchanges are available to bring select TDR-94/94D transponders to DO-260B statuses.

ADS-B Out takes affect in Europe on June 7, 2020. The mandate only applies to aircraft with a Maximum Take-Off Weight (MTOW) more than 5700 kg (12566 pounds) or with a maximum cruising speed more than 250 knots.

Both are Garmin kit part numbers for the GTX-335 ADS-B panel mount transponder with internatl WAAS GPS that can be sold over-the-counter without dealer installation.

Both include the transponder w/ WAAS, GA-35 antenna, STC product registration, installation kit, and pilot's guide.

PN K10-00276-04 additionally includes the GAE-12 altitude encoder and high-speed multi-charger.

We recommend going to the L3Harris website which has many anwers to common questions about installation, software and other topics.

Yes, the RANGR Lite is meant for owner/operators who do not have an ES (Extended Squitter) upgradeable transponder or WAAS GPS in their aircraft. The less expensive unit (TXL) is Transmit only while the other (XVRL) includes ADS-B In as well which will display (traffic and weather) on the GNS-430 but would be need to be interfaced.

First, we would recommend contacting a local Garmin dealer to discuss the following:

  • Upgrading your existing nav/com to a used GNS-530W or the newer GTN-750.
  • If you already have a Garmin transponder (i.e. GTX-330), then you should simply get the ES upgrade, interface to GNS-530W or GTN-750, along with a few other minor installation considerations, and get the shop to do the appropriate paperwork based on Garmin's AML STC.
  • If you do not have the GTX-330, then you should just consider pursuing one of the GDL systems from Garmin. Most likely the GDL88 which will give you In/Out capability. Same interface and installation considerations as above apply. Please note ADS-B In is not required for the mandate.

UPDATE

5/9/2018

Bendix/King, L3 and ACSS released the NXT-700/MST-70B as form fit replacement for the MST-67A. It is DO-260B compliant to meet the ADS-B Out mandate.

There are other options besides the MST-70B to gain ADS-B compliance. There are various STCs that allow the removal of the Bendix/King transponder system and installation of Rockwell Collins or Garmin transponders. Upgrade prices vary depending on actual installed equipment. 

Regarding ADS-B for the Garmin GTX-330 transponders, the best solution is to simply have the units converted by Garmin to include the ES (Extended Squitter) upgrade. This upgrade is about $2000 approximately. Additionally, a WAAS/GPS source will need to be interfaced. We can process the upgrade for you or any other Garmin dealer can as well.

First, please reference the information Garmin provides in relation to the ES upgrade:

http://www.garmin.com/us/intheair/ads-b/seven-questions/

There is perhaps a misconception that simply having your Garmin GTX-330 transponder upgraded to include Extended Squitter capability is the only step for ADS-B Out compliance. As with almost all ADS-B installations, appropriate interfacing to other systems in the aircraft (ex. approved position source & altitude source) is required along with approved guidance material that indicates the airworthiness approval procedure followed for return to service of the aircraft (ex. AML STC). Garmin provides an Installation Manual with Approved Model List STC for its Aviation dealers. Authorized dealers should not be distributing the necessary data and paperwork for the ADS-B installation to non-dealers.

As with all ADS-B installations, Southeast Aerospace strongly recommends that you only contact and consult a trained, authorized avionics dealer.

No. Southeast Aerospace strongly recommends that you only contact and consult a trained, authorized avionics dealer for all ADS-B installations.

One of the reasons for much of the confusion, controversy, and misinformation surrounding ADS-B is due to those in the aviation realm who are minimalizing or ignoring key aspects of an ADS-B installation. Most if not all ADS-B installations are not a “box-swap” regardless of any advertising or information on the Internet stating as much. Even if you were to seek alternate, unauthorized methods to obtain ADS-B equipment or upgrades to existing equipment, you still need a way to get it in the aircraft and approved by the FAA. Most ADS-B product manufacturers only offer AML STCs they have to authorized dealers in their network.

If you want to be compliant and able to fly in 2020, then just get the job done right the first time. Unfortunately, some people in aviation always try to cut corners on avionics installations by underestimating the job at hand in hopes to save a buck. It never works out to your advantage no matter how it looks on the bottom line on the frontend of the job. The old saying holds true for ADS-B installations especially – “Pay Now or Pay Later”.

If you want your installation done right the first time legally and technically, then contact a trusted avionics shop that has formal training on ADS-B and the related products from the OEM. Or, contact the OEM and ask for a recommendation in your area. Most OEMs are more than happy to refer to a legitimate, quality dealer in your area.

Citation S550 equipped with: Transponders MST-67A 066-01143-2101. Chance to update to ES?

Garmin GPS400. Chance to update software to WAAS? Or maybe to replace with a GPS400W and link it with transponders? - FMS UNS-1L SCN 803.1. Citation Mustang C510 equipped with G1000 Integrated Flight Deck. It is a 2008 plane.

What can I do to get ADS-B at an affordable price?

A: Since the aircraft are operated in Spain, what region or ADS-B spec do you need to meet? (i.e. USA, DO-260B?)

Without knowing exactly what ADS-B requirement or mandate you might be trying to comply with, I can only provide information relative to what we know here in the USA in reference to ADS-B for Part 25 aircraft.

For the Citation 550, the MST-67A will be superseded by the MST-100B if/when Honeywell can produce and certify the MST-100B. I have attached the only details that we currently have on the MST-100B. Honeywell has not even released pricing on this unit yet, however, ideally it would be an ideal solution ultimately since it is said to be plug and play with the MST-67A. With a WAAS GPS interfaced it would meet all ADS-B mandates. Also, keep in mind, that your CAS-67 can be upgraded fairly easily to Change 7.1 via Honeywell sales bulletin upgrading the TPU-67A processor to the TPU-67B. There is a company that offers some STCs for Part 25 aircraft if your region requires an STC for the 7.1 upgrade - http://www.prostaraviation.com/

If the MST-100B does not pan out for some reason and/or Honeywell keeps delaying its release, then there is a company named Jettech that has released Garmin GTX 3000ES ADS-B capable transponder to its existing STC covering Garmin GTN install on Citation and Citation Jet aircraft equipped with TCAS II. In addition, the company amended its Garmin GTN autopilot coupled LPV FAA STC for the Citation 500 series to include all Primus 1000 equipped Bravo, Ultra, Encore and Excel aircraft. They do not have much information on their website about the ADS-B STC but I recently learned about it at the AEA convention last week - http://jettechllc.net/index.html

Regardless of what direction you might go in, you should most likely get your GPS-400 upgraded to the GPS-400W while Garmin is still offering the upgrade. It is relatively inexpensive at around $3000 USD. Most FANS type systems will require WAAS GPS input or accuracy ultimately. Plus, Garmin's WAAS interface tis very compatible with most ADS-B solutions. Regarding the Citation Mustang C510 equipped with G1000, Garmin is still working on this solution. We assume it will include the GTX-3000 transponder(s) as this aircraft will require a 1090 MHz, (not 978 MHz UAT) system. I would continue to monitor Garmin's website for announcements relating to the G1000.

In most cases, if you already have Garmin equipment, the easiest route to comply with ADS-B is to stay with Garmin. Based on what you gave me below, you would need to upgrade your GNS530 to the 530W (WAAS) and replace your GTX327 with the GTX330ES (Extended Squitter). Most shops will give you a trade-in value for the GTX327 and there are some used GTX330ES units out there on the market. This route will make you compliant with the 1090ES part of ADS-B compliance.

Otherwise, if you choose to keep the GTX327 and go with the GDL88 or GDL84 UAT (978 compliance), you will still have to get your GNS530 upgraded to WAAS and then handle some additional considerations.

Unfortunately, the GPS in the KMD-150 does not comply with any of the requirements for GPS performance in the latest ADS-B mandate or DO-260B. More or less, although it is not specifically referred as such, current WAAS GPS receivers are the only GPS receivers that meet the performance requirement needed for ADS-B Out.

Considering your current situation, here are a few possible scenarios for you to comply:

  1. Keep the KMD-150 with GPS as a stand-alone navigation aid and pursue the KGX-150 with internal GPS. This would of course require installing a separate WAAS GPS antenna on your aircraft for the KGX-150. In addition, you would not receive any of the ADS-B In benefits since the KMD-150 is not an interface for that. However, there are many options to display ADS-B In information on anything from smartphones, tablets, etc.
  2. Replace the KMD-150 with some sort of Garmin GNS or GTN navigator which will meet the approved position source requirements for ADS-B. I would recommend their GDL-84 or 88 boxes for the UAT portion of the equation however there are a few other manufacturers offering less expensive UAT solutions like Free Flight with their Ranger Lite product.


The second option is obviously going to be more expensive but gives you a little more versatility and more capability in your aircraft. I only included UAT (978) options because I am assuming that you are flying below 18,000 feet.

A few questions related to the KGX 150 :

  1. Can this unit be paired with the KT-76C transponder?
  2. What will the Wi-Fi option cost?
  3. With our configuration, what antennas will need to be installed to meet the ADSB-Out requirements?
  4. Will an additional antenna be required to facilitate ADS-B-In?

There are a few things to be aware of with all UAT installations. These units require a control device and a switch to place them in air/ground mode. The switch is not a major issue and is a minor cost. However, the controller is additional if the aircraft is not already equipped with a transponder and/or display (MX20 for example).

As you’ll see below, yes, the KT-76C will pair with the unit via the antennas. Basically the UAT will sense the XPDR. This will enable you to send the Mode A and IDENT information to the UAT unit. However, you are still required per the FAA to have a way to know your ADS-B status. If a suitable display such as the Garmin MX20, Aspen EFD1000 or the KSN 770 is not installed, then a remote control unit is required. The KGX Control Panel list price is currently $619. Depending on the aircraft and the kind of flying, there are a lot of factors and options to consider.

  1. Can this unit be paired with the KT-76C transponder?
    • Yes
  2. What will the Wi-Fi option cost?
    • The Wi-Fi option will run around $349 list for parts.
  3. With our configuration, what antennas will need to be installed to meet the ADS-B-Out requirements?
    • Per the STC, you will be required one external WAAS/GPS antenna and at least one UAT antenna.
  4. Will an additional antenna be required to facilitate ADS-B-In?
    • No, as long as the unit purchased is the transceiver. However, you will need a suitable display for the "In" without the Wi-Fi.

In regards to your RV-6A, upgrading to the GTX 330ES will take care of your 2020 requirements for ADS-B. As you already have a GTX 327 and a GNS 430W, you may be more pleased with the installation of a GDL 88 standard. The prices of the units are similar even once you add the new antenna for the GDL-88 (give or take about $150). The labor to install the GDL 88 will be more, but with the GDL 88 you will get free weather and traffic on the GNS 430W. This would then free up the Garmin 696 and the GDL 39 for your Luscombe.

In regards to your 1947 Luscombe 8-E, your options are not as straight forward. You have no WAAS/GPS receiver in the aircraft so one of the UAT units like the GDL 88/84 from Garmin, NGT-2500 from L-3, or the RANGR 978 from Freeflight will be your best option to give the ADS-B Out. The RANGR 978, with its control head (required per the installation manual), may be the least expensive option but all three will have a fair amount of labor for the installation.

Since SEA is a Rockwell Collins dealer, we can perform this modification. Some of the equipment for this modification can be sold in serviceable condition, but we cannot sell factory new without performing the upgrade ourselves. There are several components required to perform this modification as well as wiring changes and additions. We’re happy to discuss this modification in more detail with you and gather the information necessary to provide you with an accurate proposal.

Portable ADS-B Out systems, also known as "suitcase" units, should not be operated (transmitting) aboard any aircraft. While marketing associated with these units may imply approval for use by way of an FCC license, the FAA prohibits their use for the following reasons:

  1. The positioning of portable, suction-cup GPS antennas associated with these units often require they be affixed to front or side windows or glare shield to obtain a usable signal. Such antenna placement obstructs the pilot's view. Connecting wiring also interferes with aircraft controls and instruments.
  2. ADS-B Out avionics require a valid Mode S code to be transmitted to operate properly with ATC automation and other ADS-B aircraft. Mode S codes, also known as the ICAO code, are assigned to an aircraft during registration and then programmed into transponders and ADS-B Out avionics. Mode S codes remain static until a change in aircraft registration or identification (N-number) occurs. Portable units require users to input the Mode S code assigned to each aircraft flown. A high number of Mode S code entry errors have occurred with this procedure, which prevent proper target correlation within ATC automation systems (target drops/traffic conflict alerts), which have resulted in increased workload and unnecessary distractions for pilots and controllers.
  3. The positioning of ADS-B antenna is also vital in the quality of the signal that is transmitted, and if capable, received by the ADS-B device. There have been a number of aircraft identified using portable ADS-B devices that result in degraded performance due solely to poor antenna location.

The KLN-94 is not a WAAS GPS, nor is it upgradeable to one. We recommend the KT-74, but if you decide to upgrade to a GPS400W or GNS430W, then you would want to go with a GTX-330.

The FAA Rebate program has come to and end. Please reference the FAA's webite for more information. https://www.faa.gov/nextgen/equipadsb/rebate/faq/#q0201

Other discount opportunities include the following:

1. Fleet or multiple aircraft discounts. Many avionics shops will offer significant discounts for multiple aircraft ADS-B upgrade committments. 

2. Avionics vender sales bulletin special pricing. Avionics venders will, from time to time, come out with special pricing on specific equipment or equipment combinations. Sometimes the equipment pricing is tied to certain airframes. Avioncs shops often times pass these special pricing opportunites on to the customer. Special pricing bulletins always have an expiration date for equipment ordering and shipping so be mindful that pricing can change drastically if you do not commit. 

3. Avionics upgrades beyond ADS-B. When performing ADS-B upgrades along side of EFIS, Radio, or other upgrades discounts can be extended due to aircraft access and equipment bundle pricing.
