As all of you might know (I blab alot) I recently sat on a B743 and considering the two planes are somewhat similar I noticed that after one notch of flaps the flap tracks go to a fixed deployed position and then dont move at all. I guess that is something that happens when you have triple fowler flaps (which are awesome). Are you aware of this and if you like i made many videos of the flight although they are not hi-res.
