A selection of articles in SKYbrary relating to events which included Wake Vortex Turbulence as a contributory factor.
- A319 / B744, en route near Oroville WA USA, 2008 (WAKE HF AW) (On 10 January 2008, an Air Canada Airbus A319 en route over the north western USA encountered unexpected sudden wake vortex turbulence from an in trail Boeing 747-400 nearly 11nm ahead to which the pilots who then responded with potentially hazardous flight control inputs which led to reversion to Alternate Control Law and aggravated the external /disturbance to the aircraft trajectory with roll up to 55° and an unintended descent of 1400 feet which with cabin service in progress and sea belt signs off led to cabin service carts hitting the cabin ceiling and several passenger injuries, some serious.)
- C185, Wellington New Zealand, 1997 (HF WAKE LOC) (On Monday 3 March 1997 at 1014 hours, privately owned and operated Cessna 185 encountered wake turbulence from previous departing aircraft, the pilot lost control of the aircraft at a height from which recovery was not possible and the aircraft descended to the ground.)
- SF34, vicinity Sydney Australia, 2008 (WAKE LOC) (On 3 November 2008, a Saab 340B being operated on a domestic passenger flight by Regional Express AL was tracking in daylight to join a 7nm final for Runway 34R at destination Sydney, when a passenger sustained minor injuries as the result of a transient encounter with turbulence that had led to a momentary loss of control of the aircraft and which was suspected as being of wake vortex origin.)
- P28A / S76, Humberside UK 2009 (WAKE) (On 26 September 2009, a Piper PA28-140 flown by an experienced pilot was about to touch down after a day VMC approach about a mile behind an S76 helicopter which was also categorised as 'Light' for Wake Vortex purposes rolled uncontrollably to the right in the flare and struck the ground inverted seriously injuring the pilot. The Investigation noted existing informal National Regulatory Authority guidance material already suggested that light aircraft pilots might treat 'Light' helicopters as one category higher when on approach and recommended that this advice be more widely promulgated.)
- A388/A320, vicinity Frankfurt Germany, 2011 (LOS LOC WAKE HF) (On 13 December 2011, an Airbus 320 was allowed to depart from runway 25C at Frankfurt on a left turning SID just prior to the touchdown of an A380 on runway 25L. The A380 had then initiated a low go around which put it above, ahead of and parallel to the A320 with a closest proximity of 1nm / 200 ft, in breach of the applicable wake vortex separation minima of 7nm / 1000ft. The Investigation found that there had been no actual encounter with the A380 wake vortices but that systemic ATC operational risk management was inadequate.)
