Wake Turbluence Groups Size Chart
Studies have shown that atmospheric turbulence hastens wake breakup, while other atmospheric conditions can transport wake horizontally and vertically. When the vortices of larger aircraft sink close to the ground within 100 to 200 feet, they tend to move laterally over the ground at a speed of 2 or 3 knots.
Wake turbulence Group A is equivalent to the SUPER wake turbulence category, and Groups B and C are equivalent to the HEAVY category.

Wake Turbulence SECTION 2 2 2.0 Introduction The Pilot and Air Traffic Controller Guide to Wake Turbulence is one part of the Wake Turbulence Training Aid. The other parts include Section 1, Wake Turbulence - Over-view for Training Aid Users Section 3, Ex-ample Pilot and Air Traffic Controller Wake Turbulence Training Program Section 4, Wake
In addition to wake turbulence categories, ICAO also specifies wake turbulence groups. These are based on wing span as well as maximum takeoff mass. There are seven groups, A to G. 2 Wake turbulence groups were introduced to enable reduced separation requirements, although in some cases separation is increased. They are used when permitted by
The area affected by the wake turbulence of a helicopter is larger than the area affected by the wake turbulence of an aeroplane of comparable size and weight, to speeds below 70 knots. Outwash Photo courtesy of the Royal New Zealand Air Force Downwash Blade tip vortices Figure 4 Wake turbulence 7
Understanding Wake Turbulence Categories Ensuring Safe Aviation Operations Wake turbulence is a phenomenon that occurs when an aircraft generates vortices in its wake, which can create hazardous conditions for other aircraft flying in close proximity. To manage this risk and ensure safe aviation operations, wake turbulence categories have been established by regulatory authorities around the

These wake turbulence categories are used in the application of wake turbulence separation minima as detailed within Section 1 Chapter 3 of the MATS Part 1 CAP 493. We have developed a database that includes those aircraft types most commonly provided with air traffic services in the UK, their MCTOM, and their ICAO and UK wake turbulence
The FAA is currently researching reduced wake turbulence separation standards to allow greater airport capacity. This is being done by re-categorizing aircraft into six categories, up from the current five. A test program is underway in Memphis, home of Fedex, who operates a great number of wake turbulence aircraft.
