Mmmmm ....
Ok ... Heli Ops (Offshore) in the UAE at the moment do NOT have to operate to PC1 requirements.
I do not know if they have to in the State of Qatar .... I very much doubt it.
As 'Griffo' and I both know the decks on most 'jack ups' used in the Arabian Gulf are generally a bit on the small size and therefore I really doubt if a "back up' type take off procedure is used ... it'd be a short route to either disaster or un-employment to do so! (and I might add I recently lost a collegue to what has been assumed to be a 'backing up accident' so I'm a bit sensitised to them).
As "DB" indicated ... the 'normal' take-off is 'usually' to a hover then to lift to 25-40' above the deck if nothing untoward has occurred then 'rotation' happens and using the a/c momentum to clear the deck if it were to go wrong from that point.
NOW can we keep this thread on track with the regard the 139 bonding issues ... especially as I see there is another thread has been started to take care of the rig takeoff 'red herring' ...
Cheers
