737 airspeed unreliable QRH
A few days back I received a new procedure in my 737 QRH, for airspeed unreliable. We now have a set of thrust settings in combination with a specific pitch attitude, as memory items.
Config flaps up: 4 degrees pitch up, and 75% N1
Config flaps extended: 10 degrees pitch up and 80% N1
This afternoon we were happily flying along at FL400 at M.79, pitch was 2.5 degrees and N1 was 89%.
My point is this: if our airspeed was going haywire at that point, the new procedure would require us to increase pitch to 4 degrees, while retarding thrust to 75%!!! At FL 400????
No way.
Where did this procedure come from? My airmanship is going to prevent me from following these new memory items. I refuse.
