yesterday i was playing around with the lago f16 intercepting some AI traffic. i came onto a 777's tail and started to follow the contrail in then about 0.2 miles back my wings broke off and i plummeted to the ground.I have "allow collisions with other aircraft" checked but i was so far back that i dont think that it falls under this category. even though i have experienced crashes with other planes when i definatly didnt come into contact with them i was so much further from the aircraft that i'm certain it was something else.i've never heard of wake turbulence being modeled in FS.....could this be it?callum

ActiveSky's got it. Did you hapen to look around to see if you had hit "another" AI aircraft? I too am unsure if it is modeled in the FS defulat sim.

FS does not model wake turbulence. It could be that another aicraft hit you while you were preoccupied or the crash boxes for the two aircraft were overlarge and FS detected a collision even if the 3-D models didn't appear to touch.

FS Meteo also models wake turbulence as well. As the previous person wrote, the collision detection is far from perfect. I was flying close to traffic with an F-16, and collisions would happen all the time, even though the replay clearly showed nothing on the planes was touching.

One other thing to consider is that crash detection for aircraft uses a spherical algorithm based on a certain radius from the plane's center. That means that there will always be more "invisible" crashes above and below then when another aircraft is at the same altitude.Crash detection for buildings is rectangular and thus more closely matches the actual geometry of the visual model.
