Functional Analysis and Operational Assessment of an Onboard Glide Path Guidance System for Visual Approaches (Visual Approach Monitor Vam)

摘要

A function and error analysis was carried out on the visual approach monitor (VAM), a head-up display system for manual visual approaches. Its operational characteristics as regards guidance performance and stability were investigated in simulation and flight tests. Flight tests show that under the chosen test conditions the VAM system produces no detectable increase in accuracy compared to visual approaches. However, it leads to significantly reduced scatter and extreme values in almost all flight guidance parameters. The VAM system is approximately comparable to instrument landing systems in its overall guidance performance.
