In relation to ELTs, what is the difference between short messaging and long messaging?
Long messaging transmits longtitude and latitude. Short messaging does not.
Why do some parts indicate "REQUEST" or “RFQ” on the Southeast Aerospace website?
In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.
In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.
What is the service life for most ELT 406 MHz?
It depends on the make and model of the ELT. However, most 406 ELTs have a battery life of either 4 or 5 years. Most batteries can transmit for as long as 24 hours.
What is the difference between the Programming Dongle and Programming Adapter from Kannad?
The Programming Dongle (P/N S1820514-06) is a portable memory module that contains the identification information for an aircraft. This dongle usually remains on board the aircraft and allows for an unprogrammed ELT to quickly be programmed with the aircraft identification information. The dongle is programmed via PC interface by an Kannad authorized distributor or shop.
The PR600 Programming Adapter (P/N 1201570) is the computer interface adapter needed to program the ELT usually on a bench type setup. Authorized Kannad programming training is required to utilize the PR600 for programming ELTs.

Why should you install a 406 MHz ELT in place of an existing 121/243 MHz ELT?
After February 1st, 2009, Emergency Locator Transmitters (ELTs) operating on the 121.5 and 243 MHz will not be monitored by the COSPAS-SARSAT satellite system. There are many false distress signals and searches initiated each year with ELTs. The newer 406 MHz ELTs transmit unique aircraft information allowing authorities to contact an aircraft owner before a search is initiated. Therefore, 406 MHz significantly decrease the amount of unnecessary searches.
While 121.5 MHz is the international distress signal, it has limitations in relation to the search and rescue efforts that would follow the activation of this frequency by an ELT. Accuracy to a crash site of an aircraft with a 121 MHz ELT can be up to 20 miles. With the enhanced performance of the 406 MHz ELT and programmed aircraft information, accuracy is improved to 2 miles.
After February 2009, the 121/243 distress signals will only be detected by ground based receivers such as air traffic control, local airports, or other aircraft. Therefore, the search and rescue efforts related to an aircraft with an older ELT could be limited and will take longer, especially in a remote location.
Some aircraft owners do not respond positively towards FAA mandates. The February 1st 2009 ELT date is not a deadline to comply with any sort of ELT mandate. As mentioned, this date only applies the discontinuance of 121/243 ELT monitoring by the COSPAS-SARSAT satellite system. Therefore, aircraft owners must decide what value to place on their safety and survival should they be put in an emergency situation where the ELT would be activated.

Why should I consider purchasing a programming dongle with a Kannad ELT?
A programming dongle can be programmed with aircraft information and easily stored or transported. This dongle provides quick programming when connected to an ELT.
Some of the more common reasons and applications for a dongle are:
- Aircraft being ferried from one country to another
- Ownership transfer of an aircraft
- Aircraft tail number change
With the relatively low cost ($240 Retail) and the hazmat shipping considerations for 406 ELTs, it is much more cost effective for an owner to purchase a dongle to the owner to change their programming.

Why does my 406 MHz ELT need to be programmed?
Programmed aircraft information is essential for search & rescue, should the ELT be activated. When activated, the ELT will transmit your identifier.
An Emergency Locator Transmitter (ELT) should be programmed with either the aircraft tail #, a serial #, or the aircraft operator designator. The aircraft information programmed is determined by your country's requirements. The information is sent to the government agency responsible for keeping the database of the country in which your aircraft is registered.
The ID is linked to your SAR database, containing valuable aircraft information: Type of Aircraft, Address of Owner, Telephone # of Owner, Aircraft Registration #, and Alternate Emergency Contact, etc.
Keeping this information up to date & accurate is a major concern of the Search & Rescue Centers. Without accurate information, valuable time may be lost in attempting to locate the owner of the aircraft.
Your ELT can easily be programmed by a certified repair station, such as Southeast Aerospace.
