Abstract
A computerized system for examining single engine performance capabilities and developing alternate routes/routings for two-engine aircraft in compliance with FAR 121.19 (driftdown, one engine inoperative) such that an attendant loss of altitude will not result in the aircraft dropping below a net flight path altitude and clearance distance with respect to the earth's surface along a given route between a flight originating point and a destination. Included as a part of the computation are the radius of action fuel capabilities which takes into consideration the "maximum continuous thrust", the power demands on the remaining engine, air density-temperature change attendant with altitude loss, and real time wind conditions.
