Offshore take off and landings
Margins ,
If you can get hold of the RFM of the AW-139 you'd get a fairly good idea of Offshore take offs and landings including sight pictures for LH or RH side landings .
It however does not answer all you questions of subsequent climbs after the take off segment is complete .
If you have obstructions ,adequate guidance is not provided and would need to be ' intelligently applied '
Hope this helps ??
Cheers
