ABSTRACT:
A safety device for a loading bridge or walkway at which aircraft are parked for loading and unloading of passengers and cargo through an open door in the aircraft. To prevent the open door from striking the floor of the loading bridge or walkway and thus from being damaged when the position of the aircraft is lowered at fuelling and loading operations, a sensor is provided in the region of the part of the loading bridge facing the aircraft and beneath the open door. When struck by the door the sensor activates an actuator which lowers the bridge a short distance.
