2) "for the purpose of taking off" ..... Pilots were logging P1 for moving the aircraft under it's own power when there was no intention of taking off.
Ground runs? Engineering testing?
Someone, somewhere will always think of a loophole and that is why all rules, legislation and regulations are written in this manner. Spend enough time reading this sort of English, and you get used to it! LASORS isn't too bad; try some of the Taxes Acts!!
