Software prevents fatal crashes, scientists sayBy Bruce Rolfsen - Staff writer

An F-16 pilot takes aim at a ground target, losing track of just how steep and low his jet is. Too confused to eject, he crashes.
Every year, one or two pilots die because they couldn’t get their bearings in time. Now, scientists for the Air Force and Lockheed Martin Corp. think they can virtually eliminate those fatal accidents with onboard computer software that takes control of the Fighting Falcon when it goes into a deadly dive.
“We looked at past accidents and this would have prevented 98 percent of them,” said Don Swihart, program manager of the Fighter Risk Reduction Program at the Air Force Research Lab.
The F-16’s flight control system activates the software when it determines — by comparing altitude, speed and direction with a virtual map of the terrain below — that the plane is within 1.5 seconds of crashing.
The software pulls the fighter into a 5-G climb until it reaches a safe altitude and is flying level. Only then does the computer return control to the pilot.
