Windshear Escape Manoeuvre
..From my QRH (737NG)
Push TOGA, this puts the AFDS in G/A mode,
Disconnect AT and AP! (AP drops off anyway if youre single channel)
MAX Thrust, (manually)
Aggressively pitch up to 15 deg or stick shaker wichever comes first. Disregard the Flight Director.
Pray you've got enough air under the wings
Wait untill youre out of the WS
Then clean up and have a chat with ATC
I would never leave automatics in, you'll need both hands on the control column with the stong pitch up moment cauesed by the engines. No time to start messing around with the autothrottle if its not doing what you want.... anything other than full thrust.
hope it clears some things up. seems to be quite a bit of confusion around here.
be safe!
