AO-0306 — Wake Turbulence Separations (for Arrivals) based on Static Aircraft Characteristics

Optimization of the ICAO wake turbulence separation classes by use of longitudinal wake turbulence static pair-wise separation (S-PWS) minima on arrivals, applicable in all operating conditions. The specification is based on the comparison of wake generation and wake resistance between aircraft types, using aircraft type characteristics, to align on reference pairs considered as acceptable baseline. This allows reduction of separation minima for most aircraft pairs, enabling runway throughput increase compared to ICAO scheme, whilst maintaining acceptable levels of safety.

Rationale
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 defined based on the worst case in each category, this leads to over separation in many instances. This means that each category may cover a wide range of different sized aircraft, what leads to over-conservative separations in many cases, and so a loss of runway throughput. Using knowledge gained with RECAT-EU development and refined analysis supported additional operational data, further optimization is possible.
