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.

A defined area surrounding the FATO which is kept free of obstacles other than objects required for navigation purposes.
Surface Level Heliport:
A heliport located on the ground or a floating heliport located on the water.
Touch Down and Lift-Off Area (TLOF):
A load-bearing area on which a helicopter may touch down or lift off.
A complex surface along the side of the safety area and part of the side of the approach/take-off surface that slopes upwards and outwards at a 1:2 slope to a height of 45m.
Flight Path Divergence:
The outer edge of the flight path beginning at the outside edge of the safety area and diverging at a uniform rate (10% day use, 15% night use) from a line parallel to the center line of the flight path.
Obstacle Limitation Surfaces (OLS):
Consists of a plane in space defining the approach surface, take off surface, and transitional surface.
