Flying Complex Approach Paths Using the microwave Landing System 861771

A piloted simulation study was conducted to examine the requirements for using electromechanical flight instrumentation to provide guidance for manually controlled flight along complex, curved approach paths within the microwave landing system signal coverage. The data from these tests indicated that flight director guidance is required for the manually controlled flight of a jet transport airplane on complex, curved approach paths. Each of the three guidance algorithms tested could be used to fly the paths. However, pilot comments indicated that the use of guidance based on capturing the next straight path segment may not be acceptable since full-scale lateral deflections normally resulted during turns. Pilot comments indicated that all the approach paths tested could be used in normal airline operations. Approach paths with both multiple, sequential turns and short final path segments were demonstrated.
