Elevated heliport. A heliport located on a raised structure on land.
Final approach and take-off area (FATO). A defined area over which the final phase of the approach manoeuvre to hover or landing is completed and from which the take-off manoeuvre is commenced.

Runway-type FATO. A FATO having characteristics similar in shape to a runway.
Safety area. A defined area on a heliport surrounding the FATO which is free of obstacles, other than those required for air navigation purposes, and intended to reduce the risk of damage to helicopters accidentally diverging from the FATO.
Static load-bearing surface. A surface capable of supporting the mass of a helicopter situated upon it.
Touchdown and lift-off area (TLOF). An area on which a helicopter may touch down or lift off.
