Cat A Offshore Helideck procedure of AW139
I wonder if we are able to do Part E and I, Offshore Helideck procedure at the elevated Helideck on the land.
The name of the procedure is Offshore Helideck but Maximum Altitude for Offshore Helideck CAT A Take-Off as well as Landing is 5000 ft Hp/Hd.
I don't think there is such a high Offshore helideck and I think the procedure above mentioned is not only for real offshore helideck.
The only problem I have now is that there is the description on Part E Page S12-E5 as below;
If the Take-Off Weight would require a drop down, during a single engine failure, it is assumed that the height of the Elevated Helideck
is greater than the Drop Down plus a height clearance margin as required by the Competent Authorities, and that there are no obstacles
beyond and below the deck edge.
