Abstract

A system and method is provided for improving efficiency of aircraft gate services and reducing time spent by an aircraft parked parallel to an airport terminal wherein aircraft utilities and gate services provided during turnaround are supported by an arrangement of flexibly movable, service and utility-carrying extendable passenger boarding bridges that enable passenger and baggage exchange concurrently with connection of utilities and provision of gate services to the aircraft. Baggage transfer is facilitated by conveyors mounted on one or more loading bridges and designed to provide a direct connection between an aircraft and a terminal. Aircraft are maneuvered by a pilot into and out of a parallel parking location in a forward direction by an engines-off electric taxi system, enabling loading bridge, utility, and service connections to be made to multiple aircraft doors as soon as the aircraft reaches a parking location and then quickly disconnected upon departure.

First claim

The invention claimed is:

1. A method for improving aircraft gate servicing and efficiency of baggage transfer and reducing aircraft turnaround time at an airport where aircraft driven autonomously without aircraft engines by engines-off electric taxi systems are parked with a longest axis of the aircraft parallel to an airport terminal, comprising:
a. at an airport terminal with a plurality of parallel parking locations providing for each parallel parking location at least two spaced flexibly movable extendable passenger loading bridges with a terminal end attached to the airport terminal and an opposite aircraft end for attachment to the aircraft in locations spaced apart a distance corresponding to a distance between the aircraft front and rear passenger access doors, activating and controlling engines-off electric taxi systems on the aircraft, driving the aircraft with the engines-off electric taxi systems in a forward direction from a landing location to the airport terminal, turning the aircraft, and parking the aircraft in one of the plurality of parallel parking locations with the longest axis of the aircraft parallel to the airport terminal with the front and rear passenger access doors in a side of the aircraft facing the terminal, and aligning with the at least two passenger loading bridges;
b. as soon as the aircraft is parked at the parallel parking location, simultaneously extending the at least two passenger loading bridges, connecting the aircraft ends to the aircraft front and rear passenger access doors, and forming at least two perpendicular parallel connections with the at least two passenger loading bridges between the airport terminal and the aircraft;
c. providing baggage transfer structures supported by two of the at least two passenger loading bridges and directly connecting the baggage transfer structures between a cargo hold of the aircraft and a baggage handling services location in the airport terminal when the two passenger loading bridges are extended to form the perpendicular parallel connections with the aircraft;
d. concurrently transferring arriving passengers from the aircraft through one of the front or rear passenger access doors and one passenger loading bridge perpendicularly connected to the airport terminal and transferring departing passengers from the airport terminal through another parallel passenger loading bridge connected perpendicularly to another of the front or rear passenger access doors, and simultaneously transferring arriving passengers' baggage using the baggage transfer structure supported by the one passenger loading bridge and departing passengers' baggage using the baggage transfer structure supported by the another parallel passenger loading bridge; and
e. when all departing passengers have entered the aircraft, all baggage has been transferred, and the aircraft is cleared for departure, retracting the at least two passenger loading bridges, activating and controlling the engines-off electric taxi system, and driving the aircraft with the engines-off electric taxi system in a forward direction away from the parallel parking location to a takeoff runway.

2. The method of claim 1 , further comprising connecting the one passenger loading bridge to the front passenger access door, connecting the baggage transfer structure supported on the one passenger loading bridge between an aircraft front cargo bay located in baggage transfer connection with the baggage transfer structure and the airport terminal baggage handling services location, and providing baggage transfer services between the aircraft front cargo bay and the terminal baggage handling services location simultaneously with passenger transfer.

3. The method of claim 1 , further comprising connecting the another passenger loading bridge to the rear passenger access door, connecting the baggage transfer structure supported on the another passenger loading bridge between an aircraft rear cargo bay located in baggage transfer connection with the baggage transfer structure and the airport terminal baggage handling services location, and providing baggage transfer services between the aircraft rear cargo bay and the terminal baggage handling services location simultaneously with passenger transfer.

4. The method of claim 1 , further comprising providing baggage transfer and handling services between the aircraft and the airport terminal by accessing at least one of a front or rear aircraft cargo bay with a baggage handling extension of the one or the another passenger loading bridges and conveying baggage directly to the terminal baggage handling services location with a reversible conveyor supported under a corresponding the one or the another passenger loading bridge.

5. The method of claim 1 , further comprising providing baggage handling services for an arriving aircraft as soon as the baggage transfer structures supported by the two parallel passenger loading bridges are connected perpendicularly between the aircraft cargo hold and the airport terminal baggage handling services location, and completing the baggage handling services for a departing aircraft when all departing passengers have entered the aircraft.

6. A method for improving efficiency of baggage transfer during aircraft turnaround and reducing time aircraft driven by engines-off electric taxi systems spend parked parallel to an airport terminal, comprising
a. controlling the aircraft engines-off electric taxi system and driving the aircraft in a forward direction from a landing location to one of a plurality of parallel parking locations along a ramp-facing side of the airport terminal and an internal terminal baggage transfer system and parking the aircraft in an orientation wherein a longest axis of said aircraft is parallel to the airport terminal and front and rear passenger access doors on one side of the aircraft face the airport terminal;
b. at the plurality of airport terminal parallel parking locations providing a number of flexibly movable extendable and retractable passenger loading bridges positioned and spaced apart at intervals corresponding to a distance selected to establish simultaneous perpendicular parallel connections through the number of passenger loading bridges between the airport terminal and front and rear doors of the aircraft driven by the engines-off electric taxi systems and parked in one of the parking locations parallel to the airport terminal;
c. providing baggage handling and transfer conveyors supported by at least two of the number of passenger loading bridges and, as soon as the aircraft is parked parallel to the airport terminal, extending the at least two passenger loading bridges supporting the baggage handling and transfer conveyors, connecting the at least two passenger loading bridges perpendicularly with each terminal facing passenger front and rear access door on the aircraft, and providing multiple parallel passenger and baggage transfer connections for transferring passengers and baggage between the airport terminal and the aircraft;
d. simultaneously with the transfer of arriving passengers exiting the aircraft and entering the airport terminal through a designated front passenger access door and connected passenger loading bridge and departing passengers leaving the airport terminal and entering the aircraft through a designated rear passenger access door and connected passenger loading bridge, transferring baggage between aircraft cargo bays and the internal terminal baggage transfer system with the baggage handling and transfer conveyors; and
e. when all departing passengers are on the aircraft, all baggage is transferred, and the aircraft is ready for departure, retracting the at least two passenger loading bridges, controlling the engines-off electric taxi system, and turning and dri
