May I add we were departing from MCT in the summer at around 40degC, under British CAA rules. Even the good engines are not producing 100pc at that temp.
That's the problem, UKCAA rules and 40C.
Answer?
Use FAA rules (after all, that is where the airplane was originally certificated) and wait for cooler nightime temperatures.
Some folks just simply cannot apply practical procedures to a situation to come up with a workable completely safe solution.
But nooooo, the UKCAA wants to reinvent the wheel.
