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.
How can I safely clean and disinfect my Garmin avionics?
Garmin has provided Service Advisory 2051 for general recommendations, materials, and supplies to clean and disinfect Garmin products. Otherwise, not following the recommendations could void the warranty.
- Cleaners containing ammonia will harm the anti-reflective coating on many Garmin aviation display lenses.
- Disinfectant with a solution of 70% isopropyl alcohol that does not contain ammonia is preferred. Solutions of up to 91% isopropyl alcohol are also acceptable.
- Clean the display lens using a clean lint-free cloth and a cleaner that is specified as safe for anti-reflective coatings.
- For other exposed surfaces such as knobs, buttons, and bezels, a damp cloth with soap and water is acceptable.
- Bleach-based cleaners, ammonia-based cleaners, or other harsh chemicals on any surface are not recommended.
- Remove all soap/soap residue to prevent buttons and knobs from gumming up or becoming slippery.
- Many aviation products are not rated as waterproof. Spraying or wetting the units to the extent where moisture could go beyond the exterior surfaces could damage the unit.
Can the Garmin GTR-225 radios be used in place of the BendixKing KY-196A/B radios?
Yes but there are installation factors to consider. It is very enticing to overwhelmingly consider the Garmin GTR-225 radios over the BendixKing KY radios since the Garmin radios can be puchased at a fraction (50%+) of the cost of the BendixKing radios. We are referring to New radios not used/reconditioned. However, it should be noted that the Garmin radios are approximately .3 inches higher than the KY radios. The rear mount cutout height for the KY radios is 1.30"; front mount is 1.35". The Garmin GTR cutout is 1.65" for rear mount and 1.77" for front mount.
Can frequencies in the GTR-225 be searched by airport identifier?
The GTR-225 contains a large database of Com frequencies that may be recalled by airport identifier.
Does the GTR-225 contain a database?
The GTR-225 contains a database with worldwide frequency data. With an appropriate GPS source, the GTR-225 locates nearby airports/airspace and their associated frequencies.
What versions of the GTR-225 are available?
The GTR-225 (10 watt) Com radio operates in the aviation voice band, from 118.000 to 136.975 MHz, in 25 kHz steps (default). For European operations, the additional Com radio configuration of 8.33 kHz steps is provided with the GTR-225A (10 watt) and GTR-225B (16 watt).
How many recent Com frequencies can the GTR-225 store?
The last 20 Com frequencies that have been used are kept in the list of recent com frequencies and can be accessed in this function.
What is required to update the frequency database on my GTR-225?
The GTR-225 uses a standard USB memory device to load the frequency database. The memory device is not provided by Garmin. The Frequency database is stored internally and the USB memory device is only used to transfer the database into the unit.
Can the nearest frequencies be searched within the GTR-225?
The GTR-225 will report the 25 nearest Airports (APT) frequencies, when interfaced with an appropriate GPS receiver and frequency database.
