But I have read here before that changing the flaps while on the take-off roll (e.g. if you realise they are not set correctly) is absolutely verboten in normal/revenue operations. So, do I understand correctly that a different set of rules apply for touch and go training flights?
In normal/revenue ops I would expect that if the flaps were found not to be set correctly during the take off run then it would be more likely that not enough flap was deployed, as opposed to too much.
