Looking in my Traffic 360 AI folder within FSX for the A380 (4) of them I have the following for the wing span within the aircraft.cfg folders for each: wing_span=94.75
That seems to be the problem and as expected, it was an error in the Traffic 360 program, not KLAX. A Wingspan of 94.75 ft ( 28.8 mt ) will allow that AI to be parked in spots as small as 15 mt of radius, which is clearly wrong.
Remember that FSX always gives preference to the smallest parking spot that can take any given plane which means, if a 30 mt spot and 20 mt spot are both available, an airplane with a wingspan of 28.8 mt will go into the 20 mt spot.
