> It has been reported that this was an "extra price" option for the jet, and it is that choice that makes it feel negligent to me. not quite. the things they offered for extra were the AoA sensor readouts and an annunciator for AoA disagreement. the mcas was not part of that and the mcas was not briefed in the difference training from the other 737 models. the mcas taking input from a single sensor was to blame. it should not have activated when there was substantial disagreement from the two sensors. it also should have 3 sensors and vote on agreement and not just difference.
