Garmin has launched its first Head-up Display, the GHD 2100. It’s for super-midsize, midsize and light business aircraft and the launch customer will be Cessna for its in-development Citation Longitude, already fitted with Garmin’s G5000 flightdeck.

Garmin’s HUD (GHD) projects a view of pertinent flight information while integrating with Garmin Integrated Flight Decks. It will make its public debut at EBACE 2017.

The GHD is a compact, self-contained projection system with a large 30-degree by 24-degree field-of-view. Driven by the Garmin Integrated Flight Deck, the GHD projects a familiar presentation of critical flight information, symbology and more, contributing to increased safety and operational benefits and providing optimal situational awareness throughout every phase of flight.

“Industry studies indicate that flying with a HUD is safer in reduced visibilities, deteriorating weather conditions and in challenging environments,” said Carl Wolf, Garmin vice president of aviation sales and marketing.

“We’ve worked hard to harmonise the GHD and Garmin’s Integrated Flight Decks so pilots are provided with a seamless in-flight experience throughout the cockpit. Pilots can expect the innovation and future growth potential available with the GHD to be matched with the same forward-thinking advancements we’ve cultivated for more than a decade with the Garmin Integrated Flight Deck and many other avionics solutions.

“We are proud to expand our long-standing relationship with Textron Aviation by providing the latest HUD technologies on the new, state-of-the-art Citation Longitude business jet.”

Compact with a wide angle field-of-view

A small, compact projection system allows the GHD to be integrated into a variety of business aircraft cockpits while also maintaining comfortable head clearance.

The GHD delivers a 30-degree, wide angle field-of-view and is placed at a comfortable viewing distance from the pilot’s head. Information is displayed in an easy to read format and is said to deliver 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 optimise 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.

Flight Path Marker-based flight director

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.

Utilising 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.

Synthetic Vision

Pilots are provided with an enhanced level of situational awareness with SVT, which presents a 3D depiction of terrain, traffic, obstacles, the runway environment and more within the GHD, supplementing the outside view with pertinent flight information.

A powerful graphics processor generates the synthetic vision view, which closely resembles the same SVT view on the Garmin Integrated Flight Deck. Because the synthetic vision image replicates what the pilot would see outside the cockpit on a clear day, pilots can more easily transition from flying with the GHD to the flight display or outside view.

Future growth

Future options such as integrating with external cameras, including Enhanced Vision Systems (EVS), provide significant improvements in situational awareness in fog and other low visibility situations. Future capabilities also include integration with a Combined Vision System (CVS), which blends EVS and SVT images to present pertinent levels of detail to the pilot, particularly during approach and landing.

The GHD also allows the operator to pursue Special Authorization Category I (CAT I), as well as Special Authorisation Category II (CAT II) Instrument Landing System (ILS) approach minima.
