Garmin is pleased to announce a new series of VHF NAV/COM radios, the GNC 255 series. As the replacement product for the popular SL 30 model, the GNC 255 series NAV/COM radios include a breadth of new features to reduce pilot workload, while also offering an affordable solution to meet the requirements of the 8.33 kHz channel spacing mandate.
These products have truly reinvented the stand-alone aviation COM radio with novel features like reverse database look-up and the COM monitor function, which bring new efficiencies to cockpit radio management. Beyond that, these products demonstrate Garmin’s commitment to aviators worldwide, providing the solutions they need to meet the latest regulatory requirements in their regions.
The series offers a variety of original features never seen before in a stand-alone COM radio. A unique frequency database makes it easy to find all the frequencies associated with a given airport or facility just by entering the location name or station ID. And when manually tuning a frequency, the reverse lookup function will automatically provide the navaid and/or airport identifier. Pilots can also find the nearest airport, area control center, flight service station, weather frequencies and VORs. All models also include a COM monitor function, which provides the utility of two receivers in one, allowing the pilot to listen to transmissions like ATIS without leaving the active ATC frequency, as one example.
The GNC 255 series automatically store the 20 most recently called frequencies. Plus, the radios allow for storage of up to 15 favorite frequencies such as the pilot’s home airport or other frequently visited destinations.
A familiar flip-flop feature allows channels to be entered in a standby window, and then activated with a press of a button. All models also include a built-in, voice activated two-place intercom. Making it a great solution for a two seat aircraft without an audio panel. And a built-in timer can assist with approaches, holds and other assigned manoeuvres.
The GNC 255 series NAV/COM radios offer all of the same COM features, while also adding navigation capability with VOR/ILS with Glideslope. The GNC 255 series works well with select Garmin flight displays including the G500, G600, G500H and G3X to display the NAV indicators in the primary field of view, and can integrate with most autopilots.
