Yes, that is pretty much how I understand it also. But this brings up a very interesting point.
Lets say that you are operating a S76A in the off shore configuaration....you are on the rig and you have more than 9 passengers on board.....your helideck is 100' above the water.....as you aircraft leaves the deck you are now within the H/V chart.
So from what you said in the above post you are not in compliance with your C of A and your insurance is now void.
