BOAC, #222
2) There is nothing in the BEA report to suggest that the pilots caused the climb either.
Other than the sidestick input, yes ?.
Something that occurred to me is the fact that the sidestick transducer,
which translates physical input to electrical signal, could have failed
in such a way as to provide a bias in it's output. Don't have enough
info to know if it uses a synchro, resolver, potentiometer or optical
encoder, but any but the last of those could in theory degrade to
provide a bias away from zero, (ie: nose up) depending on failure mode.
Probably a long shot, but it is a possibility...
