GNC 355: GPS/Comm Radio with LPV Approaches

We’re excited to introducing the GNC 355 – a GPS navigator with Localizer Performance with Vertical (LPV) approach guidance, complete with a built-in Comm radio. With the new GNC 355, pilots can take advantage of the benefits of WAAS/SBAS GPS guidance, while also incorporating a modern Comm radio into their existing avionics stack. Intended for Class I/II aircraft that weigh 6,000 lbs./2,721 kg. or less, as well as experimental/amateur-built (EAB) aircraft, the GNC 355 Supplemental Type Certification (STC) is imminent and will be available in August from Garmin Authorized Dealers for over 700 aircraft makes/models.

“Based on the popularity of legacy products like the GX 60 and the GNC 250/300XL, as well as customer excitement for our new GPS 175 and GNX 375, we’re pleased to bring the GNC 355 to market,” said Carl Wolf, Garmin vice president of aviation sales and marketing. “The GNC 355 gives value-minded customers a simple upgrade path to a GPS navigator with a number of capabilities including WAAS/LPV approach guidance, wireless connectivity, a modern Comm radio, and with its standard mark-width form factor, pilots can easily add the GNC 355 without overhauling the panel of their aircraft.”

Aircraft owners can easily incorporate the GNC 355 into an existing avionics stack because of its standard 6.25-inch wide by 2-inch tall design. A vibrant, colorful and responsive touchscreen display boasts a familiar Garmin user experience, while a dual concentric knob and home button offer added versatility when interfacing with the touchscreen. The user interface has been optimized for the screen size of the display, while also retaining a familiar menu structure similar to other Garmin products. 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.

Fully WAAS/SBAS IFR-approach-capable, the GNC 355 gives pilots the benefit of flying LPV, as well as Area Navigation (RNAV) approaches. Many approaches offer vertical approach guidance as low as 200- feet above ground level (AGL). Pilots can also leverage 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. Visual approaches are also available within the GNC 355 and provide lateral and vertical approach guidance in visual flight conditions.

Two versions, the GNC 355 and GNC 355A, are available with 25 kHz and 8.33 kHz frequency channel spacing respectively. 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. Recent, nearby and saved frequencies also offer easy access to frequency information. For example, with built-in standby frequency monitoring, pilots can listen to ATIS while monitoring tower frequency simultaneously. The airport identifier and frequency type are also displayed below the frequency so pilots can communicate with confidence.

An array of interface options include the G3X Touch flight display for experimental and certificated aircraft, the G5 electronic flight instrument, the GFC 500 and GFC 600 autopilots, as well as select third-party autopilots. Course deviation and roll steering outputs can also be coupled to the GFC 500/GFC 600 autopilots and select third-party autopilots so procedures such as holds, radius-to-fix (RF) legs and missed approaches may be flown using the autopilot. Aircraft owners can also retain many of their existing flight instruments, audio panels and many legacy CDI/EHSI indicators such as the KI 208/209 products.

Additional interface options include pairing the GNC 355 with a dual-link Garmin Automatic Dependent Surveillance-Broadcast (ADS-B) solution, such as the GTX 345 or GDL® 88. When paired with these products, the GNC 355 is capable of displaying subscription-free Flight Information Service-Broadcast (FIS-B) weather and ADS-B traffic targets, which includes patented TargetTrendTM and TerminalTrafficTM. Wireless Connext® cockpit connectivity offers flight plan transfer via Bluetooth® to and from compatible portables and mobile devices running the Garmin PilotTM and FltPlan Go applications. Pilots can also use the Flight Stream 510 to access the wireless benefits of Garmin’s Database Concierge, which uploads aviation database information from the Garmin Pilot app to the GNC 355 in minutes.

The GNC 355 provides a number of additional benefits, including graphical flight plan editing, allowing pilots to more easily edit their flight plan based on an ATC amendment or weather. Features such as FastFind simplifies flight plan entry by applying predictive logic to suggest airports and waypoints using current GPS location, while Smart AirspaceTM makes it easier to identify pertinent airspace on the moving map. The addition of SafeTaxi® airport diagrams display runways, taxiways, Fixed Based Operators (FBOs), hangars and more relative to the aircraft’s location on the airport surface.

The GNC 355 and GNC 355A are expected to be available in August and will be approved for installation in over 700 Class I/II piston aircraft models that weigh 6,000 lbs./2,721 kg. or less. The GNC 355 and GNC 355A can purchased through the Garmin Authorized Dealer network at that time starting at a list price of $6,995 and $7,695 respectively. European Union Aviation Safety Agency (EASA) validation is expected at a later date. A free GNC 355 trainer app is also available for download on Apple mobile devices, which allows customers to explore the feature set. We will also be showcasing the GNC 355 next week at the Garmin exhibit during the 2019 EAA AirVenture fly-in, in Oshkosh, Wis., July 22-28, 2019. The GNC 355 is supported by our award-winning aviation support team, which provides 24/7 worldwide technical and warranty support. For additional information, visit www.garmin.com/generalaviation.
