Operational direction: distribution
The percentage of days on which departing flights head east or west is dependent on the wind direction.
Graph of the distribution of operational directions
The percentage of time in which aircraft depart to the east or west (the distribution of the airport’s operational directions) is directly dependent on the wind direction because on both runways, which are aligned parallel to the east-west axis (260° and 80°), aircraft always take off and land into the wind.
The distribution of operational directions determines to a very large extent the number and level of measurements recorded at the aircraft noise measurement stations, because – based on the location of a measurement station relative to the airport or the flight path geometry – the distribution of operational directions determines whether the station measures take-off or landing noise levels or even whether it can detect any noise at all.
Regardless of the wind direction and the balance of operational directions, the runway is utilized to ensure equal traffic allocation to both the north and south runways.
