Abstract
A logic controlled APR system including arming logic, engine failure detection circuits, and system fault detector circuit means for monitoring system integrity. The logic controlled APR system detects an engine failure in a multi-engine aircraft and provides increased fuel flow to the remaining normally operating engines, and includes a disarm mode in the event of an RTO (rejected take-off).
