Choose Your Installation

The GTR 225 is available in 3 versions to fit your needs. Two of these models are available with 25 kHz frequency channel spacing (and 8.33 kHz channel spacing to meet the  Single European Sky mandate that all aircraft in Europe). It's also available with either 10 W or 16 W of transmitter output, letting you find the right balance of power and price. All 3 versions include a 2-place intercom that’s ideal for 2-seat aircraft; no additional hardware is required to communicate with your passenger. Plus, remote frequency flip-flop capability can help in demanding operating environments like helicopters, letting pilots keep their hands on the controls.

Reduce Your Workload

In addition to traditional Comm features, the GTR 225 incorporates a number of functions that can save you time and effort. Provide the GTR 225 with an airport identifier and it will automatically find its frequency (and vice versa) thanks to a built-in, updateable database. When installed with a compatible GPS source like our GTN or GNS series avionics, you can also view facility name and type when tuned to a valid station. You'll gain the confidence of knowing you're talking to the right controller every time. The Comm's database technology also allows you to store and recall commonly used or recently used frequencies by an assigned name. All information is displayed prominently on the device's large sunlight-readable LCD display so you can read it at a glance.

Never Miss a Transmission

With its standby frequency-monitoring feature, the GTR 225 gives you the ability to listen to ATIS while monitoring ATC. Swapping your active and standby frequencies is done with a single touch of a button. No longer will you have to worry about missing an ATC call or other critical transmission. You can also use the built-in timer to assist with approaches, holds and other assigned manoeuvres.

Need night vision?

For pilots flying patrol aircraft or helicopters while using night vision goggles (NVGs) to aid visual surveillance, the GNC 255 series NAV/COMM radios are available in versions that offer NVG-compatible displays. Featuring readouts and lighting designed to suppress light waves in the red to near-infrared (NIR) spectrum, these radios screen out distracting light interference for NVG operations – while providing crisp, vivid display readability under all lighting conditions, from night time to bright daylight.
