Atc Recat Weight Classes

Background of RECAT Implementation RECAT history After extensive research, the traditional weight-based system of four categories JHML of aircraft were re-categorized into seven wake groups A, B, C, D, E, F, G according to wingspan and the maximum takeoff weight in order to better accommodate growing air traffic demand.

This initially used six groups of aircraft, primarily based on weight Super A380, Heavy, B757, Large, Small, and Small. 12 The FAA continued Wake Turbulence Recategorization, or RECAT. In 2013, RECAT was extended from Memphis to 6 other airports. 12

Under the Recat program, aircraft are classified according to wingspan and the aircraft's ability to withstand a wake encounter, as well as the certificated takeoff weight. This method results in six categories of aircraft for wake turbulence separation purposes. The categories separate the current heavy and large weight classes into four wake categories two for heavy, and two for large

Wake Turbulence Recategorization - Phase II Purpose of This Order. This order provides procedural guidance to FAA Order JO 7110.65, Air Traffic Control, and the PilotController Glossary, related to the use of Wake Turbulence Recategorization Recat Phase II procedures and separation minima.

Both are Heavies over 300,000 pounds, their weight previously the only defining measure. RECAT allows more detail. The 747 is a class B Heavy, with a wingspan between 175 and 245 feet. Its twin-engine cousin's wingspan lies between 125 and 175 feet, making it a C. The more robust 747 now only needs three miles behind the 767.

Definition Wake Turbulence Re-categorisation, or Wake RECAT, is the safe decrease in separation standards between certain aircraft. Description The existing International Civil Aviation Organisation ICAO wake vortex separation rules are based solely upon aircraft weight, categorised as Heavy, Medium or Light. While safe, in some respects, they are now outdated and lead to over-separation in

RECAT 1.5 classified aircraft according to wingspan and the aircraft's ability to withstand a wake encounter, as well as the certificated takeoff weight. RECAT 2.0 described a pairwise separation matrix developed for the most common ICAO type identifier aircraft that comprise 99 of the operations at 32 airports within the U.S.

2-1. Aircraft Type Designators. An aircraft type designator is an abbreviated form of an aircraft type. This designator is used in air traffic service automation systems that exchange data. The aircraft type designator is primarily used in flight plans and air traffic service messages but may be used in other matters when needed. Appendix A of this order contains an alphabetized list of

Categories are now based on weight, certificated approach speeds, wing characteristics, along with special consideration given to aircraft with limited ability to counteract adverse rolls. RECAT places aircraft into six 6 categories labeled A-F for both departure and arrival separation.
