I've been reading about ICAO Flight Plan in Canada and how to fill it up properly and I am unsure of what time should go in the box 13.
According to Skybrary, it should be block off time.
Flight Plan Filling - SKYbrary Aviation Safety
My PPL Instructor always said box 13 was wheels off time, so now I am a bit confused.
Is there anyone who could shed some light on this?
Thanks
