| 20090119854 | AIRCRAFT DOOR DETECTOR/WARNING DEVICE - Disclosed is an electromechanical system for minimizing passenger door contact with the Passenger Loading Bridge (PLB) floor and subsequent damage to said door, during passenger loading or off loading. The system, as configured at the Cab entry, senses the proximity of the aircraft door by contacting a sensing pad, attached to the PLB floor. This initiates a sequence of events. 1) Both visual and auditory alarms are initiated to alert the passenger loading agents and/or the bridge operator of a fault. 2) The PLB is moved down and away from the door sufficiently to prevent the PLB floor from coming in contact with the door. The loading agents or PLB operator can then perform the necessary steps to reset the device and continue loading. | 05-14-2009 |
