ABSTRACT:
An elevator system for use in a wide-body commercial aircraft having multiple levels within the aircraft provides an elevator shaft that extends through at least two of the levels of the aircraft. The elevator shaft communicates with an opening in the hull of the aircraft. An elevator car is mounted within the shaft and controls and a drive unit are associated with the car to move it within the shaft and also out through the opening in the hull to provide access to and from the aircraft. At least a portion of the car remains in the shaft at all times to provide some lateral stability to the car.
