Abstract:

The report presents the results of an operational evaluation of the two-segment instrument landing approach for noise abatement purposes. The evaluation was performed using a FAA DC-9 modified with a Selective Glide Slope SEGS computer which provided the vertical guidance for the upper segment. The results indicate general acceptability of the two segment procedure for VFR operations and suitability for IFR evaluation. The SEGS computer as installed in the DC-9 was unsuitable for IFR operations autopilot operation, transition and improved upper segment termination warnings are required. Author
