For example, with built-in standby frequency monitoring, pilots can listen to ATIS while monitoring tower frequency simultaneously. Recent, nearby and saved frequencies also offer easy access to frequency information. Using the internal frequency database, airport, weather, Air Route Traffic Control Center (ARTCC) and Flight Service Station (FSS) frequencies are easy to find and can be loaded to the standby position by selecting the frequency from the airport information page. Two versions, the GNC 355 and GNC 355A, are available, the first with 25-kHz frequency channel spacing and other 8.33-kHz spacing. In addition, visual approaches are available within the GNC 355 and provide lateral and vertical approach guidance in visual flight conditions. Pilots can also take advantage of the touchscreen and moving map to generate customized holding patterns over an existing fix in the navigation database or over a user-defined waypoint and easily insert it into a flight plan.
Many approaches offer vertical approach guidance down to altitudes as low as 200-feet above ground level (AGL). “Pilots can quickly access direct-to functionality, moving map, flight plan, nearest, procedures, waypoint and terrain pages, as well as frequency information using the touchscreen, and create customizable data fields and short cuts for quick, one-touch access to important information,” the avionics maker said.įully WAAS/SBAS IFR-approach-capable, the GNC 355 gives pilots the benefit of flying LPV, as well as Area Navigation (RNAV) approaches. Garmin says the user interface has been optimized for the smaller size of the display, while the unit also retains the familiar menu structure found in other Garmin GPS navigators.
