A Gatwick spokeswoman has said the passengers involved in the emergency landing were being looked after in a specially set-up reception area at the airport.
Some incoming flights have been diverted, with some now landing at Stansted Airport in Essex instead.
The spokeswoman did not know how long it would take for the plane to be moved from the runway and normal take-offs and landings to resume.
