Hi guys,Just wondering how wake turbulence works, with AI traffic or VATSIM.I have an aircraft in visual range 8 nm ahead of me at FL340, I am at FL360 and slowly gaining on the aircraft.Will I expect to experience any wake turbulence and how is it implemented?Many thanks for your time.Armen at EGLLwww.veryquiet.com

Hi Armen,With multiplayer traffic ala Vatsim/SB3, you must use a utility such as AIBridge (www.schiratti.com/dowson.html) to add such aircraft to the AI traffic tables.The wake condition monitor looks for a 2-minute flight path of any AI aircraft. The wake is assumed to slowly descend over the life of the "trail". It will not ascend. When wake condition encountered, the effect is triggered and an oscillating rolling/pitching motion will occur, rendering a temporary loss of control until out of the "wake trail".In your example, no, you will not experience wake because you are above the wake-generating aircraft's altitude and well clear of any "wake trail".Best,

Hi Damian,Thanks for that good explanation!:)Armen at EGLLwww.veryquiet.com

Realitically, you won't expect much at all in cruise as it is in the slow-and-dirty configuration that wake turbulence is the greatest. So landing and take off are when wake turbulance is at it's greatest. I don't know how far ASV goes into this, but with their attention to realism, it's probably modelled realistically.----------------------------------------------------------------John MorganReal World: KGEG, UND Aerospace Spokane Satillite, Private ASEL 141.2 hrs, 314 landings, 46 inst. apprs.Virtual: MSFS 2004"There is a feeling about an airport that no other piece of ground can have.

Oh my,The A380 has some awful wake turbulence figures:"the A380 will require 15nm radar separation as opposed to the standard 5nm, and for vortex on final approach, anything (incl 744) will be spaced 10nm behind.....how ridiculous!"and,ICAO report "Wake Vortex aspects of the Airbus A380 aircraft" 11/10/2005: T 13/3-05-0661.SLG) Preliminary data from A380 wake turbulence test are in, and it looks like Airbus predictions are totally outside the ball park with regards to the A380 wake. Flight test data shows that the A380 wake vortices will descend further and are significantly stronger at 1000ft (300m) below the generation altitude than for any other aircraft in its weight category (747 etc). On occasions the A380 wake vortices may descend 2000ft (600M) below the aircraft and pose possible passenger comfort issues, but not a hazard. Initial ICAO guidance is as follows: 1) one additional min to be added to all separations, when the A380 is the leading aircraft. 2) Horizontal spacing on final approach to be no less than 10 NM between A380 and following aircraft. 3) vertical spacing to be no less than 2000ft when following behind the A380.
