Abstract:

This report presents the results of tests conducted in a Beech-200 B-200 simulator located at the Beech Learning Center in Wichita, Kansas, and operated by Flight-Safety International FSI. The testing was conducted to examine the feasibility of reducing approach minimums below Category I by utilizing a highly accurate navigation signal, such as the Microwave Landing System MLS, when standard Category II approach and runway lighting are not available. Results are presented which indicate that properly trained crews using flight director-equipped aircraft can operate to lower approach minima than standard Category I without fun Category II approach and runway lighting. Performance in the visual segment and touchdown performance is shown to be equivalent regardless of the availability of touchdown zone or runway centerline lighting. The benefits of a Category II approach lighting system ALSF-2 are mitigated by the fact that when the aircraft breaks out of weather at the lower decision heights DHs, i.e., 150 feet above ground level AGL, most of the approach light system is already behind the aircraft. Recommendations are made for further testing in actual aircraft. MLS, DH, Flight director.
