Controlled Airspace Airspace which has been notified as Class A, Class B, Class C,
Class D or Class E airspace (ANO).
Control Zone Controlled airspace which has been further notified as a control zone
and which extends upwards from the surface (ANO).
Cruising Level A level maintained during a significant portion of a flight (ICAO).
Decision Altitude/Height In relation to the operation of an aircraft at an aerodrome
means a specified altitude/height in a precision approach at which a missed approach
must be initiated if the required visual reference to continue the approach to land has
not been established (ANO).
Deconfliction Service . A Deconfliction Service is a surveillance based ATS where,
in addition to the provisions of a Basic Service, the controller provides specific
surveillance derived traffic information and issues headings and/or levels aimed at
achieving planned deconfliction minima against all observed aircraft in Class F/G
airspace, or for positioning and/or sequencing. However, the avoidance of other traffic
is ultimately the pilot’s responsibility.
Elevation The vertical distance of a point or level on, or affixed to, the surface of the
earth measured from mean sea level (ICAO).
Estimated Time of Arrival For IFR flights, the time at which it is estimated that the
aircraft will arrive over that designated point, defined by reference to navigation aids,
from which it is intended that an instrument approach procedure will be commenced,
or, if no navigation aid is associated with the aerodrome, the time at which the aircraft
will arrive over the aerodrome. For VFR flights, the time at which it is estimated that
the aircraft will arrive over the aerodrome (ICAO).
Flight Information Service Officer (FISO) A Flight Information Service Officer at
any aerodrome or area control centre.
Flight Level One of a series of levels of equal atmospheric pressure, separated by
notified intervals and each expressed as the number of hundreds of feet which would
be indicated at that level on a pressure altimeter calibrated in accordance with the
International Standard Atmosphere and set to 1013.2 hectopascals (ANO).
Flight Plan Specified information provided to air traffic services units, relative to an
intended flight or portion of a flight of an aircraft (ICAO).
General Air Traffic Flights operating in accordance with civil air traffic procedures.
Heading The direction in which the longitudinal axis of an aircraft is pointed, usually
expressed in degrees from North (true, magnetic, compass or grid) (ICAO).
Height The vertical distance of a level, a point, or an object considered as a point
measured from a specified datum (ICAO).
Holding Point A speech abbreviation used in radiotelephony phraseology having
the same meaning as Taxiway Holding Position or Runway Holding Position.
Identification The situation which exists when the position indication of a particular
aircraft is seen on a situation display and positively identified (ICAO).
IFR Flight A flight conducted in accordance with the Instrument Flight Rules (RoA).
Instrument Meteorological Conditions (IMC) Weather precluding flight in
compliance with the Visual Flight Rules (ANO).
Known Traffic Traffic, the current flight details and intentions of which are known
to the controller concerned through direct communication or co-ordination.
