Wake turbulence report

Airservices is currently working towards a reduction in wake turbulence separation for some aircraft types, based on the work of the ICAO Wake Turbulence Study Group (WTSG), FAA and Eurocontrol.

The proposed reductions have the potential to introduce capacity increases of between four and seven per cent.
As part of the implementation of RECAT-AUS, data is required on the incidence of wake vortex encounters that currently may be experienced. This data collection must occur before states may introduce reduced spacing.
