I want you to imagine that whilst sitting in your comfortable business class seat on the 747 landing at LHR the Captain comes on the PA and explains to the pax that he is now handing control to the co pilot because from his seat he cannot actually see the runway.
Crazy - yes.... but it's what the offshore captain has to do when it's a LHS landing for he cannot see the deck once he gets to LDP.
The greatest number of incidents offshore are caused by the helicopter striking an object in the vicinity of the helideck.
