Sensor Failures

With the MAX we have two AoA failures that both triggered the stick shaker and several actuations of MCAS.

Blocked pitots took down AF447, and others.

Blocked statics have taken down at least two, Lima and Santo Domingo.

AH failure took down a 747 out of Mumbai.

Others with better memories likely know of more.

None of these crews diagnosed the failure in time. Often the captain will prefer his instrument readings to those on the copilot side or the standby. But common factors, such as tape or icing can take out entire sensor suites.

Crews get presented with engine failures on recurrent sim checks. Sensor failures should also be included, but of course this will call for more sim time to the great distress of bean counters.

Time to buy stock in sim manufacturers. They will be getting a bunch more business
