glide ratio
This term is a technical specification used primarily in aviation and aerodynamics. It describes the efficiency of an aircraft's wing in maintaining lift while descending, effectively measuring how far a plane can travel horizontally for every unit of altitude lost.
In practical application, a higher glide ratio is highly desirable as it provides the pilot with more options and a larger safety margin during an engine-out emergency. It is a constant value for a given aircraft configuration at a specific airspeed, though it can be influenced by external factors like wind speed and direction.
Meanings
Examples
The glider has an impressive glide ratio of forty to one.
I need to calculate the glide ratio to see if I can reach the runway.
A higher glide ratio allows a pilot to cover more distance while descending.
Check the glide ratio before you commit to the approach.
The aircrafts glide ratio decreases significantly when the flaps are extended.
The aircrafts glide ratio decreases significantly when the flaps are extended.
If the engine fails, the glide ratio determines where the plane can land.
I wonder if this new wing design will improve the overall glide ratio.
The instructor explained how weight affects the glide ratio of a sailplane.
