Changi vortex study to examine separation intervals

Aviation authorities in Asia and Europe are to conduct a joint study into wake turbulence to determine whether the distances between aircraft can be reduced while maintaining safety standards.

The Civil Aviation Authority of Singapore (CAAS) and the European Aviation Safety Agency (EASA) will cooperate in a study of aircraft wake turbulence at Singapore's Changi Airport. If the study finds that current separation minima can be safely reduced, runway capacity at Changi-and other airports around the world-could be increased.

The vortices created by an aircraft's passage through the air vary in strength from a variety of factors, including the aircraft's size.

Due to the safety hazard posed by wake turbulence, an aircraft following behind another aircraft must maintain adequate safe distance. The minimum safety separation between two aircraft, in turn, determines runway capacity.
