Determination Of Runway-In-Use Aircraft

Share
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.
