Based on extensive analysis of wake vortex behavior, new procedures and separation standards are being developed and implemented in the US and throughout the world. Wake research involves the wake generating aircraft as well as the wake toleration . wake vortex while landing. Photographs courtesy of Brian Greenwood. ContentS For the purpose of assessing wake turbulence separation, aircraft are divided into the Table 3 shows the non-radar separation standards for departing aircraft using the same runway (or parallel runway separated.

Knowledge of wake vortex behavior in the operational environment has increased RECAT applies this knowledge: – Wake strength (wind loading, wing span, weight, approach speed) – Induced rolling moment coefficient circulation under today’s separation standards. Observance of these standards ensures safe separation from the ground, from other aircraft and from protected airspace (see Loss of Separation). Separation standards may sometimes serve to reduce exposure to Wake Vortex Turbulence although there are many occurences of significant wake vortex encounter at separations much greater than prevailing minimum separation. when wake turbulence separation is required. is used in lieu of describing the wake categories in paragraphs requiring wake turbulence advisories or when a pilot requests to deviate from wake turbulence separation. A reference to Paragraph , Minima, Subparagraph f was inserted where necessary. Size: KB. Current wake vortex separation minima are a major impediment to increasing air traffic capacity since they are greater than radar separation minima. The concept of dynamic wake vortex separation, which allows reduced separations in favorable weather conditions when wake durations on flight paths become shorter, would allow an increase in Size: KB.
that require special treatment for wake turbulence separation purposes (see Section 9). Descent rate: In calm air, a wake vortex descends slowly. As an order of magnitude, in cruise, it could be 1,FT below and behind the generating aircraft at a range of around 15NM. Then, when far away from the generating. Wake Turbulence SECTION 2 2 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. separation standards a limiting factor for capacity at the busiest airports. A solution to airport congestion is thus to reduce, where possible, separation minima whilst at least maintaining the current safety level. For that purpose, a characterization of the behavior of wake File Size: KB. Abstract: At airports, surface operation on the runway is the limiting factor for the overall throughput; specifically the fixed and overly conservative ICAO wake turbulence separation minima. The wake turbulence hazardous flows can dissipate quicker because of decay due to air turbulence or be transported out of the way on oncoming traffic by cross-wind, yet wake turbulence separation minima .
