but the ultimate responsibility is with the marshaling team once under their charge..
At many gates in MIA the Marshaling team has been sent packing and instead we have machines that do their job: It senses aircraft position, closure rate etc, tells you to turn left or right and to stop. It has to be manually programmed for each aircraft type and that is usually done in the Ramp-Tower.
Not sure what BA has on the E-terminal for the A-380s.
