When a helicopter is on a roof or on the deck of a ship, if simple flight model is enabled, the helicopter sits perfectly well on the deck.
However, if the advanced flight model is enabled, the helicopter sinks into the roof/deck.

This makes landing on roofs and many addon ships impossible when using the advanced flight model
I have tested this on many other things you can land on. I landed a Hummingbird on the deck of a harbor and the skids sink into it so that i cannot take off anymore.
This mostly happens if you land on objects.
(except of the hospital roof, it works fine in this case)
