SLIM GPS NAVIGATION

Created for Part 23 Class I/II aircraft (weighing less than 6,000 lbs) and experimental/amateur-built aircraft, GNC 355 provides a smart, affordable way to add next-generation navigation to your favorite airplane.

DO-IT-ALL TOUCHSCREEN

The intuitive touchscreen interface provides quick access to navigation, radio functions, multifunction display features and more.

SIMPLE INSTALLATION

The GNC 355 navigator has the same 2” height as older navigation equipment and can allow you to keep the composite legacy CDIs already in your aircraft to minimize installation cost¹.

MULTIFUNCTION DISPLAY

The 4.8” display puts moving maps, terrain, traffic, weather, SafeTaxi^® airport diagrams and more at your fingertips.

EASY DATA ENTRY

Use the on-screen keyboard or traditional concentric knobs to enter waypoint identifiers, routings and more.

PINCH, SWIPE GESTURES

A quick finger swipe lets you pan across the map display. Or use a smartphone-like pinch-to-zoom motion to scale up or down on any map, traffic or terrain page.

FASTFIND FEATURE

As soon as you start typing, the GNC 355 navigator’s FastFind feature uses quick predictive logic to suggest airport and waypoint entries by using current GPS position. Just select and go.

AIRWAYS, YOUR WAY

Victor airways can be overlaid on the map. For easy IFR routings, view airway segments available from a waypoint and corresponding exit options.

“RUBBER BAND” REROUTES

This handy feature lets you grab a flight plan leg on the screen and then stretch or move it to adjust for a deviation or ATC amendment to your flight plan.

VIRTUAL MAP TOPOGRAPHY

By referencing built-in terrain, mapping and obstacles databases, GNC 355 shows detailed surface features, cities, airports, SUAs and more on the dynamic map display.

TERRAIN ALERTING

A built-in database provides color-coded display overlays to warn when potential terrain conflicts loom ahead.

DIRECT CONNECT

A Direct-to key on almost every page lets you quickly enter a direct course for any selected waypoint. A menu of nearest airports and flight plan waypoints makes for easy entry.

MORE APPROACH OPTIONS

The WAAS/SBAS-certified GPS receiver enables GPS-guided LPV glidepath approaches down to ILS-comparable minimums as low as 200’.

CLEARED FOR THE VISUAL

GNC 355 can give advisory visual approach guidance based on a published glidepath or a 3-degree slope from the runway threshold (with terrain/obstacle clearance).

AUTOPILOT INTERFACE

Precise course deviation and roll steering outputs can be coupled to Garmin autopilots and select third-party autopilots, enabling virtually all IFR flight procedures to be flown automatically.

HOLDING PATTERNS

IFR pattern entries can be tricky. The GNC 355 navigator lets you easily create and execute holding patterns over a published or user-defined waypoint.

SAFETAXI DATABASE

Upon landing, georeferenced SafeTaxi diagrams on the display automatically help you track your location on hundreds of airports.

ADS-B DATA LINKS

When paired with a Garmin ADS-B “In” equipage solution¹, GNC 355 can display up to 60 ADS-B traffic targets as well as subscription-free U.S. weather data.
