This revision replaces AC 90-23F published 12 years ago. What has changed related to wake turbulence guidance in the last decade that necessitated a revision? Adding value to the publication is additional information on Enroute Vortex Strength, Vortex Encounter Guidance, Helicopter Slow or Stationary Hover, Super Heavy Weight Class, Winglets, NextGen Initiatives, and Wake Turbulence Mitigation for Departure (WTMD). There is also a direct link in the AC to the Aircraft Characteristics table where you can find your aircraft type and which RECAT category you are in. Would you have ever guessed that the Gulfstream 5 is in the same RECAT category as a Boeing 757? The noticeable change to the AC is the size. The revised AC is now 40% longer. Who could expect a government publication to get smaller with time? The good news is that the added pages incorporate three FAA Order publications (appendix 1-3), making some previously hard-to-find information conveniently located. The FAA will have a hard time justifying waiting another decade before issuing a revision to this AC. Appendix 2 (FAA Notice JO 7110.608) details the recategorization (RECAT) of FAA Wake Turbulence Separation Categories. Upon publication, the appendix is already outdated as Miami International Airport (MIA) incorporated RECAT standards on December 1, 2013. In the same fashion that we have seen other updated FAA publications, like the Instrument Procedures Handbook, the figures are much improved and in color. We should expect to see these figures migrate over to the AIM section 7-3-1 in the near future."}
