In regards to MCAS activation, in the Boeing 737 training manual it describes the system like this: "The MCAS only operates at extreme high speed pitch up conditions that are outside the normal operating envelope."
So while high AoA can happen while having negative pitch attitude, isn't it saying in the manual MCAS is only activated at pitch up conditions only? Or does this just mean the pilot is pulling up causing a pitch up condition which could occur during negative pitch attitude of the craft?
