Airspeed (m/s)

An unpowered aircraft trades height for distance. Its glide ratio, L/D, is exactly how many meters forward it travels per meter of descent — a modern glider does 50:1. The shallow glide angle is set only by L/D, not weight, while the sink rate and time aloft depend on speed. Vital knowledge after an engine failure.

Glide range15.0 km

Glide angle3.8°

Sink rate2.0 m/s

Time aloft8.3 min

Governing equation

γ = arctan \frac{1}{L / D} = arctan \frac{1}{15} = 3. 8^{\circ}, v_{s} = \frac{V}{L / D} = 2.0 m/s

Reading this result: Glide angle depends only on L/D, so the range scales straight with altitude; speed changes how fast you sink and how long you stay up, but not how far you reach.
