EASA publishes safety information on wake vortex -SPECIALS AVIONEWS
Cologne, Germany - At high altitude and about the applicable precautionary measures
EASA (European Aviation Safety Agency) published today a Safety Information Bulletin (SIB) to remind pilots and air traffic controllers about the risks associated with wake turbulence encounters at high altitude and about the applicable precautionary measures. Every flying aircraft generates turbulence in its wake. This wake turbulence consists of a pair of counter-rotating vortices that can persist for several minutes behind the generating airplane, naturally descending. Actual motion strongly depends on the prevailing wind and atmospheric conditions. The likelihood for an airplane to encounter severe wake turbulence generated by another airplane is very low but cannot be excluded. Typically, the so-called “heavy” and “super heavy” aircraft (A-340, A-380, B-747 as examples) are more prone to generate stronger vortices, although there is potential for other large aircraft types as well. The Agency is continuously monitoring with interested parties the risks associated to wake encounters en-route and publishes this SIB to inform the community about precautionary measures. It is possible to see the integral version of the report (seven pages) in the "Specials" section on the left side of the AVIONEWS' home-page.
