Garmin HUD projection system for integrated flight decks

May 19, 2017 // By Julien Happich
Garmin International Inc. (Olathe, KS), a unit of Garmin Ltd has developed the GHD 2100, a head-up display for super-midsize, midsize and light business aircrafts.

Incorporating modern optical design within a single display unit, the system projects a crisp, clear view of pertinent flight information while also offering superior integration with Garmin Integrated Flight Decks for a near-seamless transition between the GHD and primary flight display (PFD).

The self-contained projection system has a large 30-degree by 24-degree field-of-view and is driven by the Garmin Integrated Flight Deck, sharing a familiar presentation of critical flight information and symbology to provide optimal situational awareness throughout every phase of flight. Information is displayed in an easy to read format and delivers supreme clarity and brightness in all lighting conditions. Whether in clouds, day or night, the GHD incorporates intelligent dimming, which automatically adapts to ambient light and allows pilots to focus on flying the aircraft.

Further reducing pilot workload, the GHD offers declutter mode so pilots can optimize the display to suit their needs. The GHD boasts a simplistic control interface and offers similarities in tactile operation with the Garmin Integrated Flight Deck for an even more seamless transition throughout the cockpit.

In addition to displaying flight-critical PFD information, the GHD displays conformal attitude and flight path information overtop the real-world view, alongside navigation data, flight plan information, autopilot modes, master warning/caution annunciations and more.

Also integrated on the GHD, SurfaceWatch provides visual and aural cues to help prevent pilots from taking off and landing on a taxiway, on a runway that is too short or on the wrong runway based on performance data entered during preflight. For example, while on approach to a land on a runway that is snow-covered or in an airport environment with reduced visibilities, SurfaceWatch highlights and outlines the pilot-selected runway on the GHD and on the PFD so it’s easier to identify.

The Flight Path Marker within the GHD precisely displays where the aircraft is flying, taking into account crosswind, angle of attack and other factors that impact the dynamic position and heading of the aircraft. Coupled with a flight path-based flight director, the pilot can more easily establish desired aircraft flight path relative to the outside world.

The Flight Path Marker includes additional features such as speed offset and velocity cue, allowing for precise energy management. Utilizing the Flight Path Marker, pilots are also provided with a complete view of aircraft performance information in a consolidated area. The combination of the Flight Path Marker and flight path-based flight director allows pilots to more easily establish and maintain a stabilized approach to land.
