The freedom of movement on the apron with a wide angle of movement, the number of sensors with different capabilities and the secure connection to the aircraft cabin bring more productivity to the passenger boarding and disembarking operations.
The tunnels of these bridges can be produced with glass or steel walls, each of which creates different advantages for passengers and operators.
