glide slope
- Noun:
- The final path followed by an aircraft as it is landing: A glide slope is the precise, angled descent path that an aircraft follows during its final approach to a runway for landing. It is often established and guided by an electronic signal from an instrument landing system (ILS).
- The term "glide slope" is used specifically in aviation contexts to describe the ideal trajectory for landing. Pilots must maintain the correct glide slope to ensure a safe and smooth touchdown.
- Noun:
- The air traffic controller instructed the pilot to intercept the glide slope at five miles from the runway.
- A stable approach requires the aircraft to be correctly established on the glide slope.
- The pilot carefully monitored the instruments to stay on the glide slope during the foggy landing.
"to be on/off the glide slope": Refers to whether an aircraft is correctly following or has deviated from the prescribed descent path.
- The warning sounded because the aircraft was below the glide slope.
"glide slope guidance": The electronic or visual information that helps a pilot maintain the correct descent path.
- The airport's new ILS provides excellent glide slope guidance.
Glidepath (noun): A synonym for glide slope, referring to the same descent path.
- The glidepath for runway 27L is 3.0 degrees.
Approach path (noun): A more general term for the flight path toward a landing area, which includes the final glide slope segment.
- Descent path: The path an aircraft follows while descending.
- Final approach path: The specific segment of the landing approach that includes the glide slope.
"Capture the glide slope": The action of an aircraft intercepting and beginning to follow the electronic glide slope signal.
- The autopilot is programmed to capture the glide slope automatically.
"Glide slope indicator": A visual aid, often part of a Precision Approach Path Indicator (PAPI) system, that shows the pilot if they are above, on, or below the correct glide slope using colored lights.
