This objective represents optimisation of the ICAO wake turbulence separation classes by use of longitudinal wake turbulence static pair-wise separation minima on arrivals (S-PWS-A), applicable in all operating conditions.
S-PWS-A is the efficient aircraft type pairwise wake separation rules for final approach consisting of both the 96 x 96 aircraft type based wake separation minima (for the most common aircraft types in ECAC area) and the twenty wake category (20-CAT) based wake separation minima for arrival pairs involving all the remaining aircraft types. This allows reduction of separation minima for most aircraft pairs, enabling runway throughput increase compared to ICAO scheme, whilst maintaining acceptable levels of safety.
The S-PWS-A is applied using a separation delivery tool, where the pairwise separations will be used as input into the separation delivery tool.
S-PWS-A requires the Optimised Runway Delivery (ORD) tool to be integrated at CWP and the wind measurement or forecast on the final approach path.
This objective targets capacity constrained runways during high intensity runway operations and applies to very large, large and possibly medium airports.
NOTE: This is an "Initial" objective to provide advance notice to stakeholders. Some aspects of the objective require further validation.
NOTE FOR MILITARY AUTHORITIES: It is the responsibility of each military authority to review this Objective IN ITS ENTIRETY and address each of the SLoAs that the military authority considers RELEVANT for itself. This has to be done on top and above of the review of "MIL" SLoAs which identify actions EXCLUSIVE to military authorities.
