I know the wing walkers perform great chemistry with the marshallers when it comes to orientating planes on the ground while they are parking or being attached to pushback tugs. But during all these operations the pilots only get to see and respond to what the marshallers are signaling, while they can't really see what the wing walkers are doing from up there. So with that in mind, do pilots need in a practical way to know and understand all the wing walkers' gestures or would it only be something out of their curiosity?
Thank you!
