Definition
The descending flight path an aircraft follows from the final approach point to the runway touchdown zone, typically defined by an electronic signal (such as the glideslope of an ILS) or by visual aids (such as a VASI or PAPI). A standard glidepath is approximately 3 degrees below horizontal.
Plain English
The angled line through the air that an airplane flies down along on its way to landing. It is a steady, gentle descent aimed at the runway.
Context Anchor
You will see this term in approach and landing discussions, including how ground effect can affect the last part of the landing.
Derivation
From 'glide' (to descend smoothly through the air without power, or with reduced power) and 'path' (the line followed). Together: the smooth descending line an aircraft follows toward the runway.
Why Pilots Care
Staying on the correct glidepath keeps the aircraft clear of obstacles and positions it for a safe touchdown.
Intuition Check
“Glidepath” does not mean the engine is off. It means the aircraft’s downward path toward the runway, whether power is being used or not.
Example Sentence 1
Cleared for the approach, the pilot intercepted the glidepath and began a steady descent toward the runway.
Example Sentence 2
Near the runway the plane entered ground effect while still on the glidepath.
