The new European separation standard for aircraft wake turbulence, developed by EUROCONTROL and adopted by DSNA at Paris-CDG Terminal Area, has safely optimised wake sequencing on arrivals and delivered more accurate separation between leader and follower aircraft. With RECAT-EU, Paris-CDG controllers have been able to reduce spacing distance by up to 30%, depending on the sequencing of aircraft, resulting in a reduction in delay, aircraft flying time and fuel consumption.
EUROCONTROL has adapted ICAO standards to improve runway throughput at major European airports. RECAT-EU defines six categories of aircraft, taking into account the strength and evolution of the wake turbulence generated and the resistance characteristics of the following aircraft. The two ICAO ’Medium’ and ’Heavy’ categories have each been divided into ‘Upper’ and ‘Lower’.
