Airplane crashes and multiple alarms

Authored by: Anonymous on Wednesday, July 18 2012 @ 03:45 PM EDT

According to a TV channel I sometimes watch, there are
multiple documented instances of airplanes going down when a
badly designed airplane computer set off multiple
conflicting alarms, making it impossible for the crew to
determine which one was right.

Typically, one set of alarms say it is flying too high or
too fast and the other ones say it is flying too low or too
slow. Usually it turns out all the wrong alarms came from a
single broken sensor getting its results multiplied and
repeated by a computer that doesn't have logic for "sensor
out of range", while the true alarms come from a bunch of
non-broken sensors measuring the fatal effects of the
autopilot obeying the single broken sensor.
