The length of the take off run available plus the length of stopway capable of bearing the mass of the aeroplane.
Adult
A male or female at the age of 12 years or above.
Aerodrome
A defined area on land or water intended to be used either wholly or in part for the arrival, departure and surface movement of an aircraft.
Aerodrome elevation
The elevation of the highest point of the landing area.
Air Operator Certificate
A certificate authorizing an operator to carry out specified commercial air transport operations.
Alerting Service
A service provided to notify appropriate organisations regarding aircraft in need of search and rescue aid, and assist in such organisations as required.
Alternate aerodrome

Altitude
The vertical distance of a level or object measured from sea level.
Apron
A defined area, on a land aerodrome, intended to accommodate aircraft for purpose of loading or unloading passengers, mail or cargo, fueling, parking or maintenance.
Aquaplaning (or hydroplaning)
A situation where the tires of the aircraft, to a large extent, are separated from the runway surface by a thin fluid film.
Braking action
A report of the conditions of the airport movement areas, providing pilots the quality or degree of braking that should be expected. Braking action is reported in terms of: good, medium to good, medium, medium to poor, poor, nil or unreliable.
Children
Person who are of an age of two years or above but who are less than 12 years of age.
Circling
Not an approved approach procedure. The visual phase of an instrument approach to bring an aircraft into position for landing on a runway which is not suitably located for a straight-in approach.

- surface water of more than 3mm, or slush, or loose snow equivalent to 3mm of water, or
- snow which has been compressed into a solid mass which resists further compression and will hold together or break into further lumps if picked up (compacted snow), or
- ice, including wet ice.
Contingency fuel
A quantity of fuel carried to compensate for items such as:
- deviation of an individual aircraft from expected fuel consumption data
- deviations from forecast meteorological conditions
- deviations from planned routing and or cruising levels/altitudes
Critical phases of flight
Those portions of operations involving taxiing, takeoff and landing and all flight operations below 10,000ft, except cruise flight.
