SeaHunter and G2E provide a textbook example of great flying fully autonomous aircraft. G2E presents an interesting situation with its large rear mounted pusher engine. The propeller provides little runway clearance during takeoff rotation and landing flare. The key here was to ensure the aircraft had enough extra airspeed in both cases, that large angles of attack would not be required to liftoff or to flare. This would provide the necessary margin to keep the prop safe time after time.

​

SeaHunter on the other hand is a traditional twin with LOTS of power! This meant ensuring that the takeoff roll could be aborted quickly and safely in the event of an engine failure. Further, ensuring that the aircraft was programmed correctly to climbout at Vmc (minimum controllable airspeed for a twin engine plane) in the event of an engine failure.

The Griffon team helped make this one of the smoothest ATOL developments ever! Though neither aircraft had done an auto landing before, we had both planes doing touch and goes in about a week. Thanks to the team for having us out!
