Are certain landing procedures prescribed at night in order to limit noise pollution?

Between 10.30 p.m. and 6.00 a.m., aircraft must in principle approach the Kaag or Polder runways at Schiphol in accordance with the fixed approach route as far as possible. The aircraft then descend to the airport from an altitude of 7,000 feet (more than 2 kilometres) in a sort of gliding flight. Because there are almost no horizontal sections in the approach any longer, the aircraft no longer need to continually use extra fuel. As a result, the engine capacity remains very low almost continuously, causing far less noise on the ground. 

This transition does require different air traffic control guidance by LVNL than for the standard approach and cannot be performed at very busy times. From July 2001, LVNL instructed aircraft coming from a southerly and westerly direction for landing on the Zwanenburg runway to fly above the sea for as long as possible. Today, the Polder runway is used at night instead of the Zwanenburg runway. For landings on the Polder runway too, the aircraft enter the country at the level of Castricum. These night-time approaches were further improved in 2008.

Since 20 February 2003, aircraft that land on the Kaag runway at night also start the final descent over the sea. The aircraft enter the country just to the North of Katwijk.
