[QUOTE][Talk about 30 degrees nose up getting your attention, try 80 degrees !!
/QUOTE]

Hi TMB from JL

Suggest might be worth making a short summary of your Sydney episode for Pprune readers of this particular thread as it has a marked similarity. Although covered on earlier UA recovery posts a long time ago, it will not be readily found unless you know what you are looking for and I very much doubt if readers recall it.

In the 737 Classic simulator in Melbourne a similar upset was designed to the upset in the original post. This originated from a 737 pitch up incident from 20 years ago in USA when the pilot had a vicious pitch up near the runway. He immediately rolled the 737 through 60 degrees angle of bank to get the nose to drop. The FCTM advises to use gentle rudder to aid the nose drop if the ailerons are also ineffective.

While Airbus feel that UA recoveries are not applicable to their types because of lack of simulator fidelity, it ignores the fact that most upsets have happened in IMC and aircraft have crashed. The secret is basic instrument flying scan to recognise the upset and once that is done in a flash normal recovery action is initiated without delay.

In other words the control forces may not be replicated in the simulator but the flight instrument indications of an upset are the same for all types and basic recovery drills the same. As so many pilots have lost their basic instrument flying skills after flying glass cockpit types on autopilot, it should be mandatory for pure flying skills to be demonstrated on recurrent sim training. And that includes regular practice at UA recoveries- not merely once every three years for three minutes...
