Chris: Difficult to remember the exact details but used to get the trainee to close his eyes then put the aircraft into a dynamic noseup position whilst manually applying a large amount of nose-up THS. Usually with power on and attitudes above 30NU. The training point was to show that the THS may have to be moved manually in the recovery which is of course a control that is not normally touched in the air. I don`t believe that the AF reached those high pitch attitudes but nevertheless achieved the gross out of normal position on the THS which would have had to be addressed to regain sufficient elevator authority.
