SW
I must say I agree with Dozy in regards to the stall warning shutting off without valid data. Allowing it to operate with invalid data may indeed see more false stall warning alarms and pilots may begin to distrust the system.
It was unfortunate that the SW activated in response to ND input but basic airmanship must come into play here and identify that a nose down input cannot exacerbate a stall.
Does anyone know how SW systems operate on other aircraft without valid data?
