Claim:
1. A method for positioning an access or loading assembly against a fuselage of an aircraft during a loading or unloading process comprising the steps of: providing an access or loading assembly comprising: a positioning drive; a control system for the positioning drive; at least two multichannel scanners oriented toward an aircraft fuselage and disposed above one another at a distance from each other, each having a plurality of light emitting units operable to emit a light beam and at least one detector; performing a position determination process comprising the following steps: determining a reference position of the access or loading assembly in a docked state of the access or loading assembly by using the at least two multichannel scanners; determining a current position of the aircraft fuselage relative to the access or loading assembly at determined time intervals by using the at least two multichannel scanners, wherein light emitting units having light beams that do not hit the aircraft fuselage are switched off during the current position determining step; comparing the current position with the reference position and determining a deviation between both positions; and transmitting a signal to the control system of the positioning drive for realigning the access or loading assembly.
