Prop Express operates C-337 twin-engine, inline trust aircraft modified for Survey and Photo flights. The inline trust gives unparalleled safety in case of engine malfunctions at low altitude and/or low airspeed. Even when having an engine malfunction, this type of aircraft will maintain controllability throughout the flight envelope, from stall speed to maximum speed, and It will not yaw to one side or the other. This is a clear advantage, compared with a conventional airplane with wing-mounted engines, especially when flying low and slow inside offshore wind farms. Aircraft with wing-mounted engines needs a higher airspeed to maintain controllability, and they will yaw to the side of the malfunctioning engine.
Our 337´ has modern avionics and autopilot, new windows, new cabin, De-ice on the wings and stabilizer, hot propeller, retractable landing gear, two bubble windows (one on each side for the middle row observers) and at the right front seat a full-sized side window that will open fully for taking pictures. Our aircraft is certified for day/night IFR.
