Honeywell has received an STC from the FAA for its Primus Elite enhanced feature upgrades on the Learjet 40 and 45. The cockpit modernization replaces aging DU-870 CRT displays with DU-875 LCD monitors, which provide increased clarity, generate less heat, and offer a weight savings of seven pounds per display. The modification includes the three-in-one cursor control device for simplified one-handed scrolling on the displays, which enables users to more efficiently select charts and maps or download navigational databases.
Safety and situational awareness are improved through approach charts that show the aircraft’s position, along with charts of airport runways and taxiways. The upgrade also provides integrated maps for two-dimensional illustration of flight plans, weather, traffic, and geographical boundaries and incorporates Jeppesen charts to show geo-referenced departures and arrivals.
When the DU-875 display is used in conjunction with optional XM Weather, pilots can get real-time weather upgrades along the route and at specific destinations, a helpful feature when flying into unfamiliar airports.
In addition to the Learjet 40 and 45, Honeywell’s upgrade is also certified for the Bombardier Global Express, Dassault Falcon 900EX/900C, Embraer Legacy 600/650, the Cessna Citation X and 550/560, and the Dornier 328.
