1. A method of detecting if a UAV is operating within its flight envelope, the method comprising:
- (a) define the flight envelope of the UAV;
(b) identify the operating state of the UAV from a present time to a future elapsed time; and
(c) determine if the operating state of the UAV will be within the flight envelope at the end of the elapsed time in the future.

Abstract
A system and method for detecting if a UAV is operating within its flight envelope. The invention includes defining the flight envelope of the UAV. The operating state of the UAV is identified from a present time to a future elapsed time. The invention determines if the UAV will be within its flight envelope at the end of the elapsed time in the future. It can then command the UAV to maintain operation within the flight envelope if the operating state determined is outside the flight envelope.
