GNS 480

TheGNS 480 provides advanced integration of leading-edge technologies withthe following innovative features:

• Glideslope guidance for LNAV/VNAV (Gamma

  2) and LPV (Gamma 3) approaches, and advisory vertical guidance forother non-precision approaches with vertical path data associatedwith them
• Reversionary Modes on the Approach
• Automatic SUSPend key function
• New interfaces to Garmin GTX 330/33/320/32 Mode S/C transponders
• New interface to display traffic data from L-3 Avionics SystemsSkywatch
• New "NAV" page with a full compass rose CDI display
• Flight Planning page enhancements
• Dual GNS 480 flight plan crossfill capability
• Ability to calculate RAIM when out of Wide Area Augmentation System(WAAS) coverage
• Automatic frequency checking for ILS, backcourse, and VOR approaches
• Notification of navigation to non-WGS 84-compliant waypoints inthe active flight plan
• Ability to manually select maximum CDI scaling

As aviation’s first GPS navigator to feature precision guidancevia WAAS, the GNS 480 now meets the strictest level of certificationfor WAAS navigation. Previously, Instrument Landing System (ILS) availabilitywas needed for a precision approach in low-visibility conditions. Now,upon FAA approval, the GNS 480 will utilize satellite-based navaids forprecise lateral and vertical approach guidance—similar to ILS operations—withoutthe need for ground-based navaids of any kind, since avionics certifiedto Gamma-3 requirements meet the FAA’s standards for Localizer-equivalentPrecision with Vertical (LPV) guidance.

At the heart of the GNS 480 is a 15-channel WAAS receiver that updatesthe aircraft’s position at a rate of five times per second. LikeGarmin’s other integrated avionics, the GNS 480 provides oceanic-approvedIFR GPS/NAV/COM functionality and ILS/VOR capabilities—but doesso on a 3.8-inch (diagonal), 256-color moving-map display.

It has the built-in controls for a remote transponder, such as theGTX 33, Garmin’s new solid-state Mode S transponder that can beused to deliver traffic advisories to the GNS 480 via the FAA’sTraffic Information Service (TIS). With a TIS datalink, a pilot essentiallysees what the ATC sees, including trend vectors and altitude data ofnearby aircraft.

The GNS 480 is also seamlessly integrated to work specifically withthe MX20 multi-function display (MFD).When coupled with the MX20, range changes performed on the GNS 480 aresimultaneously refected on the MFD. When the pilot selects an approachon the GNS 480, the approach plate is automatically depicted on the MX20with Jeppesen® Chart View™. Pilots can also view a verticalprofile of the approach using the MFD’s split-screen capability.

Working in tandem with standard autopilots that accept roll-steeringcommands, the GNS 480 behaves like a high-end flight management system(FMS) by providing the necessary guidance data to fly the aircraft throughall approach procedures.
