Can someone explain the rate of pitch change?
It is but a short step from a 'fly down' demand when 'below' the false GS (and going down) to the a/c trimming back to 'hold' the false G/S and then rapidly into a rapidly accelerating 'fly up' demand if at all 'above' the false GS.
Unless the rate of change of pitch is enormous I don't understand how this can happen?
- I guess you would need to be 'there' to know. I suspect the rate of pitch was a touch high!
