It would seems that one of the Achilles' heel of modern FBW airliners is the lack of reliable airspeed measurement. Off hand I can think of obvious
AF447, the
XL Airways A320 crash or apparently the very recent
AN-148 crash.
From that latest tread I quote
Laser based speed sensors are in R&D phase, Airbus have done trials. Cost is an issue, so defense applications are likely to be first customers.
Really a discussion for another thread.
Well I'm posting here because I think this seems to be a major items that should be solved industry wide.
And regardless of the measurement itself I think that there is room for improvement in both the detection of the issue and the help provided to the crew by the automation (or lack of, as things can get rather confusing when a FBW system is presented with what should be detected as obvious bogus data).
Thoughts ?
