An example of intersecting runway use: an aircraft (red) taking off from the Aalsmeer runway may intersect with an aircraft taking off from the Buitenveldert runway (green), if the aircraft taking off from the Aalsmeer runway were to take off at the same time and from the start of the runway.
Intersecting runway use occurs if the runways physically intersect with each other. At Schiphol, this applies for the Buitenveldert runway and the Aalsmeer runway, and for the Aalsmeer runway and the Kaag runway.
In addition to the examples of safety procedures given above, it is also possible in the use of intersecting runways (depending on the circumstances) to use certain access ways and exits of take-off and landing runways, so that take-off and landing can still be performed independently of each other.
An example of independent runway use with intersecting runways: an aircraft taking off from the Aalsmeer runway (grey) is not dependent on the aircraft taking off from the Kaag runway (green), because this aircraft does not depart from the start of the runway but from a different position on the runway (access way). If the aircraft taking off from the Kaag runway did depart from the start of the runway, a jet blast hazard would arise for the aircraft taking off from the Aalsmeer runway. Jet blast is rapid air movement produced by the jet engines of aircraft, particularly on take-off.
