You may well have a point at which you make a decision during the take off but don't confuse things by calling it a take off decision point.
I would suggest calling the Decision Point in a Take Off
not a Decision Point is confusing things.
Class One, Class Two or without giving any thought to Performance, Class, or color of uniform, when you make a Decision re landing or proceeding to fly, at the point in the Take Off process you make that Decision, is a Take Off Decision Point.
What label you stick on it is your choice but the Decision Point it is.
Crab,
Please comfort us by telling us the RAF does not have any such conflicts or conundrums in its handful of Regulations, Procedures, SOP's, and Flying Orders?
