ABSTRACT:
An array of non-contact proximity sensors are mounted on the front bumper of the loading bridge to be in opposition to the airplane. The proximity sensors are interconnected to circuitry, and the approach speed of the gangway to the airplane is reduced automatically as it nears the airplane. The sensors and circuitry sense angular misalignment of the gangway with the airplane and selectively and automatically control its position relative to the airplane.
