Aerodrome control tower. A unit established to provide air traffic control service to aerodrome traffic

Aerodrome elevation. The elevation of the highest point of the landing area.

Aerodrome identification sign. A sign placed on an aerodrome to aid in identifying the aerodrome from the air.

“aerodrome operating minima” means the limits of usability of an aerodrome for:

(i) take-off, expressed in terms of runway visua l range (RVR) and/or visibility
and if necessary, cloud conditions; or

(ii) landing in approach and landing operations with vertical guidance, expressed
in terms of visibility and/or runway visual range (RVR) and decision height or
altitude (DA/H); and

(iii) landing in non-precision approach and landing operations, expressed in terms
of visibility and/or runway visual range, minimum descent altitude or height
(MDA/H) and if necessary, cloud conditions;

Aerodrome reference point. The designated geographical location of an aerodrome.

Aerodrome traffic density.
a) Light. Where the number of movements in the mean busy hour is not greater than 15 per runway or
typically less than 20 total aerodrome movements.

b) Medium. Where the number of movements in the mean busy hour is of the order of 16 to 25 per runway or
typically between 20 to 35 total aerodrome movements

.
c) Heavy. Where the number of movements in the mean busy hour is of the order of 26 or more per runway or
typically more than 35 total aerodrome movements.

Note 1.C The number of movements in the mean busy hour is the arithmetic mean over the year of the number of
movements in the daily busiest hour.

Note 2.C Either a take-off or a landing constitutes a movement.

Aeronautical beacon. An aeronautical ground light visible at all azimuths, either continuously or intermittently, to designate a
particular point on the surface of the earth.

Aeronautical chart. A representation of a portion of the Earth, its culture and relief, specifically designated to meet the
requirements of air navigation.

Aeronautical ground light. Any light specially provided as an aid to air navigation, other than a light displayed on an aircraft.

Aeronautical operational control (AOC). Communication required for the exercise of authority over the initiation, continuation,
diversion or termination of flight for safety, regularity and efficiency reasons.
