What hasn't been mentioned is AIRSPEED. The pre take-off self briefing for launch failure with a glider winch launch goes.
"In the event of a launch failure I will lower the nose"
(Winch launched gliders are climbing at about 45 degrees nose up so achieving about a 30 degree nose down attitude takes a fairly significant control input)
"I will wait until an airspeed of xx has been reached" xx normally being the approach speed for the day which depends on glider type & windspeed and is well above normal stalling speed.
The accent here on waiting is that just because you have lowered the nose does not mean that you instantaneously have safe manoevring speed. Stalling speed during the pushover will be significantly below normal and any aircraft takes a noticeable amount of time to gain airspeed after lowering the nose.
"I will assess whether I can land safely straight ahead"
"If yes I will do so"
"If I am too high I will turn left/right" and reassess" - the turn is normally away from the airfield so as to open up the whole field for landing options and the options to be reassessed are a crosswind/downwind or limited circuit approach
And if a pupil doesn't run through that lot as part of the cockpit checks the instructor will almost certainly give him a "cable break" just as a reminder.
Note the stress however on not trying any form of turn until you've got the airspeed to do it safely. You'd have to be pretty far off the deck in a lot of powered aircraft!
