AO-0324 — Wake Turbulence separations (for departures) based on Dynamic Aircraft Characteristics

Optimization of the ICAO wake turbulence separation classes by use of longitudinal wake turbulence dynamic pair-wise separation (D-PWS) minima on departures for the initial common departure path from the runway, applicable under given operating conditions, in particular given weather conditions, using dynamic input data. This allows conditional reduction or suspension of separation minima for most aircraft pairs, enabling runway throughput increase compared to ICAO scheme, whilst maintaining acceptable levels of safety.

The demand is high for airport capacity and efficiency at some European airports, and in particular for increased runway throughput.
Today's ICAO separations are based on certificated Maximum Take Off Mass (MTOM) and it includes three categories (i.e. HEAVY, MEDIUM or LIGHT) allocating all aircraft into one of them. Because the separations are static, this leads to over separation in many instances, resulting in a loss of runway throughput. Using knowledge gained with static pair-wise separation (S-PWS) development and using dynamic input data, further optimization is possible.
