Abstract:
Method and apparatus for providing an alignment indication for a nose landing gear of an aircraft. The apparatus includes surfaces that abut certain features of the nose landing gear. When the surfaces of the fixture and the features of the nose landing gear abut, the fixture is aligned with the nose landing gear and oriented such that a coherent light source emits a coherent light beam that impinges on an alignment scale. The coherent light beam can be sufficiently small that a mechanic or other user can discern the alignment of the nose landing gear to within one or two degrees. After the nose landing gear has been moved to a centered position, control rigging that communicates steering inputs from pilots to a hydraulic actuation system can be adjusted so that the steering inputs are also centered.
