Enhanced autopilot system could help prevent accidents like 2009 Air France 447 crash

Thirty lines of computer code might have saved Air France flight 447, and 228 passengers and crew aboard, from plunging into the Atlantic Ocean on June 1, 2009, according to new research by Carlos Varela, an associate professor of computer science at Rensselaer Polytechnic Institute. Varela and his research group have developed a computer system that detects and corrects faulty airspeed readings, such as those that contributed to the AF447 crash. Their approach to detecting errors could be applicable in many systems that rely on sensor readings.
