Capture-Effect and Sideband-Reference Glide-Slope Performance in the Presence of Deep Snow 1977-1978.

摘要

Results of capture-effect and sideband-reference glide-slope system response to up to 21 inches of snow in the reflecting zone are presented. These results show that the capture-effect path angle increases at 0.08 per foot of snow, and the sideband-reference path angle increases at 0.30 per foot of snow. No significant degradation in path clearance or width was observed. Data was also collected on near-field and integral monitors performance, and static path angle values at runway threshold. (Author)
