The term of runway-in-use is
applied to indicate the particular runway or
landing direction as the most suitable at any particular time. The runway-in-use
selected will normally be that the most closely aligned to the surface wind
direction especially when the wind speed is more than 5 knots. AERODROME
CONTROL TOWER will normally nominate the longest runway when the headwind speed
is less than 5 knots.
In the determination of the
runway in use, one or more of the following factors shall be considered :
a) type
of aircraft (refer to the size and weight);
b) length
of runway (refer to take-off run or landing roll required);
c) wind
direction and speed (refer to cross wind or tailwind);
d)
traffic disposition (anticipation of overshooting or traffic confliction);
e) better
approaches (refer to efficiency);
f)
shorter taxiing distance (refer to efficiency);
g)
position of the sun in relation to the runway; and/or
h)
necessity to avoid flight over populated area or other reason my be
used.
Operational shall be confined to
the most suitable runway for the majority
of aircraft/traffic. More than one runway direction shall only be used if
necessary :
a) due to
operational characteristic of a particular aircraft; or
b) to
avoid necessary delay.
The responsibility for ensuring
that sufficient length or run is available for an
aircraft operation rest solely with the pilot-in-command.
Should the pilot-in-command
advise AERODROME CONTROL TOWER that the nominated runway is unsuitable because
of operational characteristic of its aircraft, permission shall be given to him
to select a suitable runway.
It is the sole responsibility of
pilot-in-command to conduct operation where the
cross wind component exceeds the maximum permissible for his type of aircraft.
If weather in the vicinity of
aerodrome is such that there is cumulonimbus activity with the wind blowing
down the runway on the departure path of flight, AERODROME CONTROL TOWER shall
inform the pilot of the presence of the cloud and wind condition when start-up
clearance is requested. Read Airfield Inspection
