GTR 225

Packed with advanced features you’d expect to find only in costly high-end systems, the 10 W or 16 W GTR 255 is designed to streamline cockpit communications. Let the versatile GTR 225 Comm radio reduce the amount of work you do in the cockpit. Not only does the GTR 225 meet the basic needs of most pilots – including adhering to new airspace requirements in Europe – but features a number of advanced features that save you time and effort.


GNC 255

The GNC 255 goes above and beyond basic Nav/Comm duties, integrating timesaving features like reverse frequency lookup, automatic decoding of morse code, dual frequency monitoring and more.As compact as it is capable, the GNC 255 can bring powerful Nav/Comm capabilities to virtually any cockpit. Not only does the GNC 255 meet the basic needs of most pilots – including adhering to new airspace requirements in Europe – it also features a number of advanced features that save you time and effort. It also contains an internal VOR/LOC converter and 40-channel glideslope receiver.

Never Miss a Transmission


Listen to 2 Frequencies with 1 Comm


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 maneuvers.

With the standby frequency-monitoring feature in the GNC 255, you won’t have to worry about missing an ATC call or other critical transmission. The GNC 255 allows you to listen to ATIS without leaving your assigned ATC channel. Swapping your active and standby frequencies is done with a single touch of a button. Pressing and holding frequency transfer key will automatically set the emergency frequency as your active radio. You can use the built-in timer to assist with approaches, holds and other assigned maneuvers.


Choose Your Installation

The GNC 255 is available in 2 versions to fit your needs. Each version comes with 25 kHz frequency channel spacing and 8.33 kHz channel spacing to meet the impending Single European Sky mandate that all aircraft in Europe will need to operate with by 2018. The GNC 255 is available with either 10 W or 16 W of transmitter output, letting you find the right balance of power and price. It includes a 2-place intercom that’s ideal for 2-seat aircraft; no additional hardware is required to communicate with your passenger. It also contains an internal VOR/LOC converter and a 40 channel glidescope receiver. 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 Nav/Comm features, the GNC 255 incorporates a number of functions that can save you time and effort. Provide the GNC 255 with an airport or navaid identifier and it will automatically find all available frequencies (and vice versa) thanks to a built-in, updateable database. With a compatible GPS input, the device will find the nearest airport to your location and easily access its weather, center and FSS frequencies. It will also allow you to easily pull up your most frequently or most recently used frequencies. The device even automatically decodes a station’s Morse code to provide a positive identification – no audible verification required.


You can easily view distance, time and speed on the device’s bright display when you install it with a compatible GPS source like our GTN or GNS series avionics. And when paired with a G500, G500H, G600 or G3X flight display, it allows for the display of VOR and ILS indications on the PFD and can follow autopilot commands. Alternatively, you can use an HSI or CDI like our MD200-306, which has been specifically designed to work with the GNC 255.
