Abstract
A logic controlled APR system including arming logic, engine failure detection circuits, and test circuit means for testing system operating condition without engine operation. The logic controlled APR system detects an engine failure in a multi-engine aircraft and provides solenoid controlled increased fuel flow to the remaining normally operating engines, and includes a disarm mode in the event of an RTO (rejected take-off).
