A simple sketch on a TWA napkin by NASA Dryden engineer Frank W. "Bill" Burcham led to development and validation of the Propulsion-Controlled Aircraft concept. |
| Project Description |
In landings at NASA Dryden Flight Research Center, Edwards, California, on August 29 and 30, the MD-11 Propulsion-Controlled Aircraft (PCA) demonstrated software used in the aircraft's flight control computer that essentially landed the MD-11 without a need for the pilot to manipulate the flight controls significantly. In partnership with McDonnell Douglas Aerospace (MDA), with Pratt & Whitney and Honeywell helping to design the software, NASA developed this propulsion-controlled aircraft (PCA) system following a series of incidents in which hydraulic failures resulted in the loss of flight controls. This new system enables a pilot to operate and land the aircraft safely when its normal, hydraulically-activated control surfaces are disabled. |
