Abstract
An enhanced control system for an unmanned aerial vehicle adds constraints to the process of choosing a flight path in the event of an in-flight contingency, such as engine out or an encounter with jamming, which forces a diversion or unplanned landing. The constraints are: (1) ensure communications are available when needed during contingency operations; and (2) ensure signals from a global positioning system (or other navigation system) are available when needed during contingency operations.
