I was looking at some pictures of the A380 and noticed that the inboard flap guide on the left wing seems longer than that on the right. At first I thought it might be the angle of the picture, but looking at a few more photos you can definitely see that one is noticeably larger than the other. I've even managed to find one picture showing an unpainted A380 where you can seen the guide outline for the larger one on both wings.
Does anyone know why this may be and what, if any, purpose does it serve?

This is total conjecture on my part, but i guess that it could possibly be due to the assymetrical airflow caused by the fact that all the engines turn in the same direction, hence causing slightly different airflow patterns over the bottom of each wing. On its own this would maybe not require the longer fairing on one side, but this could have some effect on the tail surfaces, hence the need to deflect the airflow back out more on one side than on the other to regain perfectly symmetrical airflow over the control surfaces on the tail.

Quoting Solnabo (Reply 4): Whatï¿½s that bulky wart thing between the wings and tail?
I believe it's the tail strike protection used during the flight testing, for the minimum t/o-speed tests. Because of the much higher weight of the aircraft, it wasn't possible to use the same kind of protection that was used on the 777 and A340NG for the same kind of tests. Please correct me if I'm not correct.
