Flight Test Demonstration of Selected Curved-Segmented Approach Paths Based on Microwave Landing System Guidance.

Abstract : The report contains aircraft and pilot performance parameters, such as aircraft tracking errors, response characteristics, and pilot acceptance for eight representative Microwave Landing System Profiles. The USAF T-39 aircraft was capable of flying fully coupled and automatic curved and segmented approaches using MLS position information. The nature of the testing was designed to demonstrate an inherent MLS capability and trend rather than to provide a great amount of statistical data on the feasibility or acceptability of certain curved or segmented approaches. It is concluded from the flight test data gathered at NAFEC, Atlantic City, N.J. that the selected Microwave Landing System can be used to generate sufficient and accurate airborne data to safely perform curved and segmented approaches to landing.
