Class Information
Number: 244/186
Name: Aeronautics > Aircraft control > Automatic > Electric course control > Of aircraft on its landing course > Vertical glide path control
Description: System wherein the direction of the aircraft, or its orientation relative to its glide path, is changed from an actual glide path line to a desired glide path line to obtain the desired glide path, the change occurring in a vertical plane; the vertical plane being one that is perpendicular to the ground, extending in the direction of landing and coextensive with both said lines.
