After looking back at near-collision data the FAA collected, the FAA has given U.S. airlines three years to install software changes to collision-warning systems, saying that the warning devices that have been installed in commercial airliners as well as private businesses need to be fixed.
The FAA has known since 2009 that systems have been known to fail to monitor and track all the nearby planes, resulting in monitoring errors, a fact which could and may have already caused problems in 7000 commercial planes and 1800 business planes in the US.
If a warning system fails, and is known to fail, why is a crash which may have been the result of a warning system failure being attributed to air traffic controller error or pilot error? That’s what I’d like to know. Do we need to be looking more closely at L-3 Communications?
