On the RAAS, does Boeing or E require mandatory GA on alert? (I am aware that with AB, if the predictive windshear alert system alarms, it is a mandatory GA)
I see a reliance on the automatics, but it has been shown that the winds measured by the aircraft on final, at/near the ground, in windshear and crosswind/crabbing conditions, are not accurate. What then, are the automatics using for windspeed and wind direction?
