Glossary of Terms

Approach/Departure Path: 
An area consisting of a quadrilateral area on the surface of the earth lying directly below the approach/take-off surface.

Elevated/Rooftop Heliport:
A heliport elevated more than 75cm above the normal elevation of the ground.
Emergency Landing Area: An area where an unavoidable landing or ditching may take place with a reasonable expectancy of no injuries to persons or damage to property on the surface.

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.
An object that could have an adverse effect on the safe operation of aircraft in flight or on the ground.

Safety Area: 
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.
Transitional Surfaces: 
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.

An aerodrome used or intended to be used for the arrival, landing, takeoff or departure of vertical takeoff and landing aircraft (VTOL); Typically used in reference to a certified “Heliport” under the Transport Canada 305 and 325 regulations and standards.

A designated area, usually with a prepared surface, used for the takeoff, landing, or parking of helicopters. The term is often used interchangeably with the more proper term “Heliport.” It is typically used to define a less formally developed landing area than a “Heliport.”
