The bridge control operator needs to steer the bridge towards the airplane door for docking. The bridge controller is responsible for aligning the X, Y and Z axes to perfectly align the bridge with the airplane’s door. When the bridge is about one meter from the door, the height of the bridge needs to be adjusted. This is accomplished by positioning reed sensors and a magnet in the bridge mechanism. The bridge operator gets feedback from the reed sensors as to the exact position of the bridge and decides how much the bridge should be moved in each axes. After successful adjustment of the height, the bridge can then be docked with the aircraft door.
