Poltergeist

Hi all,

does anyone have any idea as to what is happening here? (click on the pic to see the 50 second video):



I was flying a freight job out of LESP HQ, using the LESP (Land's End SeaPlanes) scenery, at 85VA - Reedville, Virginia.

I started out in the 'shed' with my Carenado U206G Amphib - and taxied out on the water, trying to avoid the pier, when all hell broke loose.

The scenes in the video were shot after I'd already had a sideways tour of the sea area!

Collisions are disabled (necessary in AH sometimes) and the only thing I've changed in the aircraft.cfg file was to add the repaint in the video. Slew mode is disabled - and is blocked by AH in any case.

It hasn't happened again since - however, I now start from the 'runway', rather than in the hangar.

Any ideas/theories appreciated.

PS - just found a pick that better illustrates the area - the strange slewing started a few seconds after this pic:

It could be your a lousy pilot who has been drinking the contraband again Sorry that doesnt help much does it

Is it FSX or FS9?? If FSX then I have not a clue...

Not totally unusual....

the key is: "I've disabled collision"

By looking at the screenshot I can see it's FSX

Your aircraft has in fact run into an object and then it tries to "collapse" but as you have ticked that off, it tries to re-stabilize itself again, and just getting into the collision again, and again ... it then continues to either accellerate the movements or decellerate depending on the objects it runs into .... had you been in the mountains you would finally end up in a valley, or at the ice-caps at some plain area where the surroundings are of such character that it eventually forces your plane to a halt.

Going mathematics you may see this phenomena as a "Strange Attractor" which is a kind of state where the object continues to receive inputs that prevents it to find a stable state.... although the state it actually finds is a stablilised unstable state ....

Sometimes I've seen this effect while starting up at an airport, left the aircraft for some spotting, and then accidentally started my "home" aircraft, which then of course starts to move .... after been away from my aircraft watching the AI, and then return to my "home aircraft" I might find it in such a state....

Remember to engage parking brakes when leaving, and even so, do not give full throttles when you go AI-spotting :-)

Agree with that Dan.. the same can happen in FS9 too
