I spoke with a CAA inspector not too long back and he pulled out the Airlaw book and had it highlighted, and this is what he said:
many people believe that half your P2 hours count towards the ATP. Not so. The book says it in a strange way but it is taken to mean that
half of the hours toward the higher licence may be P2 time, ie. 1500/2=750 so a maximum of 750 hours may be P2 time. The rest may be Sim (to a limit, forget what it is, poss 130hrs), Dual, IF and of course P1. This is to protect against people who have never had much command time getting an ATP.
Which makes sense.
