| Aerodrome/Heliport | A defined area on land or water (including any buildings, installations and equipment) intended to be used either\nwholly or in part for the arrival, departure and surface movement of aircraft. |
| Landing direction indicator | A device to indicate visually the direction currently designated for landing and for take-off. |
| Secondary Power Supply | |
| Anemometer | Device used for measuring wind speed |
| ABN/IBN | Aerodrome/heliport beacon / identification beacon used to indicate the location of an aerodrome from the air. |
| Wind Direction Indicator | |
| RVR observation site | The observation site of Runway Visual Range. |
| Frequency Area | Designated part of a surface movement area where a specific frequency is required by air traffic control or ground control. |
| Runway | A defined rectangular area on a land aerodrome prepared for the landing and take-off of aircraft. (Annex 14) |
| Runway Direction | |
| Radio altimeter area | |
| FATO | Final approach and take-off area. 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. Where the FATO is to be used by helicopters operated in performance class 1, the defined area includes the rejected take-off area available. |
| TLOF | Touchdown and lift-off area. An area on which a helicopter may touch down or lift off. |
| Safety area | A defined area on a heliport surrounding the FATO which is free of obstacles, other than those required for air\nnavigation purposes, and intended to reduce the risk of damage to helicopters accidentally diverging from the FATO. |
| Helicopter clearway | A defined area on the ground or water, selected and/or prepared as a suitable area over which a helicopter operated in performance class 1 may accelerate and achieve a specific height. |
| Hot spot | A location on an aerodrome movement area with a history or potential risk of collision or runway incursion, and\nwhere heightened attention by pilots/drivers is necessary. |
| Apron | A defined area, on a land aerodrome, intended to accommodate aircraft for purposes of loading or unloading passengers, mail or cargo, fuelling, parking or maintenance. |
| Taxiway | A defined path on a land aerodrome established for the taxiing of aircraft and intended to provide a link between\none part of the aerodrome and another, |
| Helicopter ground taxiway | A ground taxiway intended for the ground movement of wheeled undercarriage helicopters. (Annex 14) |
| Helicopter air taxiway | A defined path on the surface established for the air taxiing of helicopters. (Annex 14) |
| Helicopter air transit routes | A defined path established for the movement of helicopters from one part of a heliport to another. A taxi-route includes a helicopter air or ground taxiway which is centred on the taxi-route. |
| INS checkpoint | |
| VOR checkpoint | |
| Altimeter checkpoint | |
| Aircraft stand | A designated area on an apron intended to be used for parking an aircraft |
| Helicopter stand | An aircraft stand which provides for parking a helicopter and where ground taxi operations are completed\nor where the helicopter touches down and lifts off for air taxi operations. (Annex 14) |
| De-icing area | A facility where frost, ice or snow is removed (de-icing) from the aeroplane to provide clean surfaces, and/or where clean surfaces of the aeroplane receive protection (anti-icing) against the formation of frost or ice and accumulation of snow or slush for a limited period of time. |
| Communication facility |
