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.

The serial number on all of our products is necessary for registration and warranty purposes.  The system ID is an internal number which is required for database updates and downloads. These updates can be done on the Fly Garmin website. Each aviation database update is downloaded specific to the system ID of each GPS, therefore if the system ID  is incorrect on our website, your aviation databases will not update correctly.

This error "0" is associated with the database program running on a computer that is not running a supported operating system. For the program to work correctly, the file must be downloaded on a computer running Windows XP or newer.

The glide path that is generated is based on the information that is used for the Localizer Performance with Vertical guidance (LPV) and Lateral Navigation / Vertical Navigation (LNAV/VNAV) procedures. It uses a specified decent angle that is centered at the MAWP (Missed Approach Waypoint) and at the TCH (Threshold Crossing Height). If this information is included in the electronic database for the approach, the 400W/500W series, G1000 with WAAS, and GTN 600/700 series will generate a glide slope.

This error message can result from a wide variety of issues. Below is a list of the most common:

• The SD card may be write protected. When write protected, data cannot be written to the SD  card. On the SD card there is a small locking mechanism that can slide up and down. To be unlocked, the locking tab should be closer to the metal contacts on the SD card. Furthermore, the process of inserting the SD  card into your Garmin device and/or SD card programmer may move the locking tab out of place.

• The card programmer cannot read or write to a high capacity card. Some card programmers cannot handle high capacity SD cards without a software download or driver update.

• There is an error or bad data region on the SD card. Perform an error checking scan of the card through Windows to correct the errors.

An altimeter does not measure altitude on the GTN-725 device. The altimeter in the aircraft measures air pressure. The altimeter is calibrated to display a certain change in altitude based on a change in air pressure. For every inch of mercury pressure change, the altimeter displays a change of approx. 1000 ft. of altitude. The GPS does not use air pressure to determine altitude and is not subject to the pressure errors in determining altitude. Therefore, the GPS derived altitude is almost always more accurate than an altimeter. Since everyone uses a pressure-based system to determine altitude, it is integral to utilize a pressure sensitive altimeter to ensure required vertical separation.

Newly Overhauled parts obtained from Garmin are designated with an N in their part number. This usually follows the 010- in the part number. As with most Garmin 010 part numbers, the N part numbers are for ordering purposes only and do not actually appear on the dataplate of the unit.
