Aircraft Glide Range

Loading author...

Estimate still-air glide range, glide time, and sink rate from altitude, speed, and lift-to-drag ratio.

L/D

Glide range

18.00 km

38.0 m/s groundspeed

Sink rate

3.17 m/s

V divided by L/D 12.0

Glide time

7.89 min

1,500 m altitude available

Glide slope geometry

Altitude converts to horizontal distance through L/D, then wind changes the ground track covered in the same descent time.
