This is all great stuff, particularly the difference between simulated and real max power take off, but it seems no-one really knows what this instructor was up to ?
It appears s/he either took off backwards in a Cat A type profile intending to abort forward (showing off and pretending to be flying to the rigs ?) or took off with the intention of aborting backwards to the take off point ?
I've only ever done two Cat A take offs so can't comment but would someone in the know care to explain the abort bit and/or whether it would ever be SOP to abort backwards ?
I ask the latter due to the reference to it being a mariner so maybe this is what you do on/off a boat or deck ?
