Abstract	Loss of control in flight has been shown to be a leading cause of accidents involving civil transport aircraft, and there is emerging evidence that loss of control is a significant issue for unmanned aircraft as well. This presentation discusses the development and testing of an upset recovery architecture that is applicable for both piloted and autonomous recoveries. The architecture was first developed for unmanned vehicles and intended for fully automated implementation. The architecture was extended for use in manned aircraft, and in particular for situations in which recoveries are being manually flown by a pilot. This extension required development of display technology for presenting recommended recovery guidance to the pilot, and modification of recovery strategies to make them suitable for execution by a human pilot. Most recently, the architecture has been extended to accommodate off-nominal vehicle dynamics, e.g., due to actuator failures, and the presentation focuses on these extensions. The approaches have been tested in multiple pilot-in-the-loop simulation experiments, which have shown both favorable pilot opinions and improved recovery performance. Ongoing research to develop enhanced algorithms for determining when to activate and deactivate an automated upset recovery system for unmanned vehicles, and stochastic simulation methods that may be useful in validating such algorithms are also discussed.
