1 RECAT-EU proposal, validation and consultation WakeNet-EU 2014 Vincent TREVE Frederic ROOSELEER ATM Airport Unit 13 May 2014

2 RECAT-EU Proposal

3 RECAT-EU RECAT-EU was developed on the basis of the joint FAA EUROCONTROL effort in RECAT-1 Following European stakeholders request, EUROCONTROL developed an revised version of the RECAT-1 proposal This proposal was built on the basis of the RECAT-1 consultation feed-back Even if the purpose was to optimize the capacity benefit for major EU airport, the categories were defined on the basis of aircraft characteristics

4 Initial categorisation of aircraft types based on clustering analysis AT72* PA28 BE99 LJ45 AT73 B732 B712* AT75* B735/B7333 E190 CRJ9 AT75 D328 B739/B736 A318/A321 T154 B767 A300 B747 A330/A340 B777 A380

9 RECAT Principles The European RECAT proposal is based on the following key principles: Leader / Follower S H M L A B C D E F S A MRS H M B MRS C MRS reduced reduced reduced reduced 6.0 D MRS MRS MRS MRS MRS 5.0 E MRS MRS MRS MRS MRS reduced L F MRS MRS MRS MRS MRS MRS Principle #1 If an ICAO WT category (Heavy or Medium) is split into an upper and a lower part, the weaker wake vortex strength generated by aircraft categorized in the lower allows reduction of separation for any follower

10 RECAT Principles The European RECAT proposal is based on the following key principles: Leader / Follower S H M L A B C D E F S A MRS Reduced 6.0 Reduced H M B MRS Reduced 4.0 Reduced C MRS Reduced Reduced Reduced Reduced Reduced Reduced 6.0 D MRS MRS MRS MRS MRS 5.0 E MRS MRS MRS MRS MRS reduced L F MRS MRS MRS MRS MRS MRS Principle #2 If an ICAO WT category (Heavy or Medium) is split into an upper and a lower part, higher resistance to wake turbulence encounters of the aircraft categorized in the upper part allows reduction of separation for these aircraft.

11 RECAT Principles The European RECAT proposal is based on the following key principles: Leader / Follower S H M L A B C D E F S A MRS Reduced 6.0 Reduced H M B MRS Reduced Unchanged Reduced Unchanged 6.0 C MRS Reduced Reduced Reduced Reduced Reduced Reduced 6.0 D MRS MRS MRS MRS MRS 5.0 E MRS MRS MRS MRS MRS reduced L F MRS MRS MRS MRS MRS MRS Principle #3 If an ICAO WT category (Heavy or Medium) is split into an upper and a lower part, the separation between upper leaders and lower followers, being the most exposed to maximum WT risk levels, remains unchanged to preserve current levels.

12 RECAT Principles The European RECAT proposal is based on the following key principles: Leader / Follower S H M L A B C D E F S A MRS Reduced Revised Reduced Revised 8.0 H M B MRS Reduced Unchanged Reduced Unchanged 6.0 C MRS Reduced Reduced Reduced Reduced Reduced Reduced 6.0 D MRS MRS MRS MRS MRS 5.0 E MRS MRS MRS MRS MRS reduced L F MRS MRS MRS MRS MRS MRS Principle #4 If the exposure to WT risk level at separation minima is to be more harmonized between aircraft types by considering the wake resistance, the wake impact evaluation allows revision of the separation for Heavy and Medium followers behind Super Heavy, when compared to a reference ICAO Heavy aircraft.
