How many runways does gatwick airport have?
Gatwick operates as a single runway airport. Strictly speaking it has two runways, however, the northern runway (08L/26R) can only be used when the main runway (08R/26L) is out of use, for example because of maintenance or an accident. The runways cannot be used at the same time because there is insufficient separation between them, and during normal operation the northern runway is used as a taxiway. It can take 15 minutes to change from one to the other.
