I have followed this thread with interest. Panning always worked for me until suddenly it didn't and I cannot understand what, if anything, has changed. The normal behaviour, for me, has been double-click the mouse scroll wheel activates the "look around the cockpit" view but the motion is not from a fixed camera location, i.e. the camera moves horizontally and vertically. A second single-click of the mouse scroll wheel and the camera becomes fixed therefore when moving the mouse the camera tilts up, down, left and right and provides the ability to pan. Suddenly, however, I cannot activate the fixed cockpit camera mode. I now can only move the cockpit camera vertically and horizontally. I don't know why the fixed camera mode has suddenly gone. I am liaising with EA Support currently. I hope this issue can be resolved.
NB: This mode suddenly disappeared a while back due to an update. Then after a few months and another update, the above behaviour suddenly appeared again. I can locate (F-14) cockpit camera mouse (only) bindings that I'm sure manage only horizontal and vertical cockpit camera movements. I have no idea where the pan bindings are for the mouse for the cockpit view. I'll aslo add that the camera works as expected in the F2 view, i.e. the camera remains fixed. Not in the cockpit now, disappointingly.
