767 inboard ailerons
Hi,
I flew on a delta 767-300er out of manchester on sunday to ATL. I was sat on the left side and noticed in the cruise that the left inboard aileron or aka high speed aileron was deflected up by about what looked to be 6-8 inches.
At first I assumed there was a fuel imbalance, but it stayed this way for the duration of the 9 hr flight. Surely an imbalance would of been dealt with. I didn't see the right side, but I don't think it was trim for yawing due assymetric thrust as I couldn't detect any yaw and surely you wouldn't fly the whole sector like that?
The only thing i can come up with is that both sides were rigged up. As a licenced engineer I can think of reasons to do this, but it looked so inefficient.
They drooped as normal with flap selection and returned to neutral with flaps up on the taxi into ATL.
Can anybody shed any light?
Thanks
