Hello, I recently noticed that the most outboard leading-edge flaps (the one next to the wingtip) do not deploy on the default 747. Is there something wrong with my software or is this a common bug? Thanks

The outboard control surfaces on the 747 (next to the wingtip) are the Ailerons, not flaps. They should function when you command left or right bank only, not when you extend flaps. Hope this helps Shaun.MikeKOCF

That would be trailing-edge. I said leading-edge. :)The 747 does not use slats, it uses leading-edge flaps. I am not sure, however, if they are Kreuger flaps or not.
