GFD selects Universal Avionics InSight for Learjet 35A/36A upgrade

GFD GmbH has chosen Universal Avionics to modernize its missionized Learjet 35A/36A fleet with the InSight flight display system. The retrofit, led with Scandinavian Avionics A/S on STC development and installation, replaces legacy cockpit instrumentation with a glass-cockpit architecture built for special-mission operations.

The program targets 16 aircraft used for aerial target and training work for the German armed forces, based at Hohn Airfield. It keeps a late-generation Learjet platform viable by extending cockpit relevance without replacing the airframe, a path more operators are now taking as avionics obsolescence tightens on legacy jets.

For suppliers and fleets alike, the deal reinforces the market for high-value retrofit STCs over wholesale fleet replacement.
