13 Conclusions and Next Steps RECAT Phase 2 provides an opportunity to explicitly define wake constraints separate from Minimum Radar Separation. This can benefit: Approaches to closely spaced parallel runways in IMC Could lead to a possible reduction below 2.5 nm for single runway spacing for certain pairs RECAT Phase 2 pairwise separations will result in benefits at all airports. More for some, less for others Phase 2 ConOps and Implementation Strategy documents are under development Need to engage international community for inputs including operators, manufacturers, and ANSPs Initial drafts, looking for input, ideas, participation 13
