It would stand to reason that this would/could also be significant on a departure. "If" still visual with the "H" of course it would have given some orientation at least.

RVDT: I wasn't meaning to mislead anyone but I had pasted that yellow "H" onto the aerial view. The actual orientation of the red coloured "H" on the pad is somewhat different and can just be made out by zooming into the second photo I posted. That orientation would bring the flight path close to one wing of the hospital.
