The approach to aircraft autorecovery demands consideration of many aspects of fighter aircraft operations and aircrew requirements. Autorecovery may include only aircraft attitude monitoring or it may also include consideration of the aircrew. A knowledge of the kinetics of Gz-induced loss of consciousness G-LOC allows early development of an inexpensive, non- encumbering, indirect method for G-LOC warning which may be followed by autorecovery if necessary. This indirect method has specific advantage for aerial combat training. Integration of an indirect monitoring system with the ground collision avoidance system currently being developed has the potential for earlier aircraft recovery. A suggested algorithm based on G-LOC physiology is given. Development of indirect monitoring systems provides valuable insight into future development of more sophisticated direct physiologic monitoring technology. It is currently not clear that the ability to reliably detect G-LOC with direct monitoring will automatically benefit aircrew during aerial combat.
