Duncan develops STC for workhorse Learjet
Duncan Aviation has helped develop an STC to add SVS to a Learjet 45 Honeywell flight deck. The upgrade improves situational awareness for the pilot and maintains the value of the aircraft.
Synthetic Vision System (SVS).

Duncan Aviation’s engineering/certification and avionics installation teams in Battle Creek, Michigan, recently worked with Honeywell Aerospace, Turbojet Engineering and Beck’s Hybrid to develop a Supplemental Type Certificate (STC) to add Synthetic Vision System (SVS) to a Honeywell flight deck on a Learjet 45 series aircraft. The Honeywell flight deck had been previously installed in the customer’s aircraft, and the cooperative effort involved upgrading the system and installing the SVS component.

Duncan Aviation has worked on this Learjet 45 in the past, installing Airshow 500, refurbishing parts of the interior, fully painting the exterior, and installing a Gogo Avance L3 for cabin connectivity.

The customer, corporate operator and retail seed company Beck’s Hybrid, explains the reasons for wanting the upgrade.

“Our 2008 Learjet 45XR is a workhorse, and it’s very dependable. We decided it was time for an upgrade and chose the Honeywell Primus Elite for several reasons. It resolved the obsolescence issues with the old DU870s, and there were cost savings with the DU exchange programme and reduced Honeywell Avionics Protection Plan (HAPP) cost,” says director of maintenance Phil Ward. “Most importantly, the upgrade increased situational awareness for the pilot with the addition of charts, integrated maps, XM Weather, and Synthetic Vision System. We also believe this upgrade keeps the Learjet 45XR value higher when compared to other aircraft without the upgrade.”
