First Claim
Patent Images
1. A method for landing an unmanned air vehicle on an inclined surface, the method comprising:
- descending vertically above the inclined surface;
detecting a pressure differential caused by the inclined surface;
counteracting motion caused by the pressure differential;
detecting when the unmanned air vehicle contacts the inclined surface;
when the unmanned air vehicle contacts the inclined surface, rotating the unmanned air vehicle until the unmanned vehicle has landed on the inclined surface;
wherein counteracting motion caused by the pressure differential includes adjusting vanes of the unmanned air vehicle.

Abstract
Takeoff and landing modes are added to a flight control system of a Vertical Take-Off and Landing (VTOL) Unmanned Air Vehicle (UAV). The takeoff and landing modes use data available to the flight control system and the VTOL UAV'"'"'s existing control surfaces and throttle control. As a result, the VTOL UAV can takeoff from and land on inclined surfaces without the use of landing gear mechanisms designed to level the UAV on the inclined surfaces.
