The orientation of a runway depends upon the direction of wind. Runways are always oriented in the direction of prevailing wind. The reason behind it is to utilize to the maximum the force of wind at the time of take-off and landing of an aircraft (Lift and drag produced). The direction of runway controls the layout of other airport facilities.
Wind Rose Diagram Type-I
It is based on direction and duration of wind.
Minimum 8 directions is taken but optimum is 16.
Data includes total percentage of time in each direction.
Concentric circles are drawn to scale according to the percentage of time wind is blowing in that direction.
Total percentage in each direction is marked on the radial line drawn in that direction.
These points on radial lines are joined together to form a duration map.
Best direction of runway is indicated along the direction of the longest line on the wind rose diagram.
