Abstract:In January 2009, a twin-engine jet ingested multiple Canada geese shortly after take-off from New York. The aircraft underwent total loss of power, but was successfully ditched on the Hudson River. In the near future, total loss of power due to bird strike may occur more often because of: 1) Increasing large bird populations, 2) Aircraft engines not being tested for large birds, 3) Birds being less able to avoid turbofan engines, 4) Prevalence of twin-engine aircraft that has reduced engine redundancy. As the image illustrates, several other twin-engine jets may undergo total loss of power (i.e. dual-engine failure) due to bird strike. During total loss of power, there is only one chance for landing because the aircraft cannot gain altitude. Thus, power-off landing is severely critical with absolutely no room for pilot error. In my dissertation, I develop an innovative software program for power-off emergency landings. During a dual-engine failure, the software program will guide the aircraft to a safe touch-down point through the optimum landing trajectory. Thereby, it can maximize the odds of a safe touch-down while minimizing the odds of crash landing, casualties and hull loss. Over 751 million annual passengers on US air carriers can benefit from this safety improvement.
