Converging runways are dependent on each other if a go-around is performed on one runway while an aircraft takes off from the other runway, or if a go-around is performed on another runway at the same time. Safety procedures are also established for this runway use.
If an aircraft makes a go-around, air traffic control assesses the risk of conflicts with other aircraft as quickly as possible and if necessary, issues additional instructions. This may mean that the departing aircraft is instructed to wait or to interrupt the take-off.
It is also possible that both aircraft will be issued with course instructions. They are then both informed about the presence of the other.
Two examples:
The flight path of a potential go-around of an aircraft due to land on the Zwanenburg runway (green) intersects with the flight path of an aircraft taking off from the Kaag runway (red).
The flight path of a potential go-around of an aircraft due to land on the Kaag runway (green) intersects with the flight path of a potential go-around of an aircraft due to land on the Aalsmeer runway (red).
In addition to the visual observation, air traffic control at Schiphol has also had a go-around detection system, GARDS, since 28 May 2015. On the basis of radar detection, this system issues a warning if an aircraft has started a go-around.
