Is it really sliding in fleet carriers? If I remember it is not sliding or rotating (which is much better imo)how "realistic" ED is one easily can see with FD´s design of FC´s!
Supposedly your platform shall lower and slide backwards into parking position (thats what U experience eg. when going to the concourse).
By design of FD thats not possible as the platforms are directly adjacent, hence mechanically would overlap..... or like M-Pad 9 that parking position would be in space.....
