The Civil Aviation Authority has approved Route 4, a westerly runway departure route for Gatwick Airport.  

Route 4 flies close to South Holmwood, Leigh, Redhill and Reigate. The revised departure route was one of nine that Gatwick implemented in 2013 so that modern satellite technology could be used for air navigation for the first time. The CAA reviewed Gatwick’s proposed new departure routes in 2015 but required proposals for Route 4 to be amended, as it did not perform as expected.  Gatwick submitted a revised proposal for the route which has now been approved.

The airport promises to explore ways to mitigate the impact of aircraft noise on all flight paths.
