Estimate glide distance using altitude above ground level and glide ratio. This free aviation calculator helps pilots with emergency planning, training, and glide performance awareness.
Enter altitude AGL and glide ratio to estimate how far the aircraft may glide in still-air conditions.
This calculator provides a still-air estimate. Actual glide distance may be shorter or longer depending on wind and aircraft conditions.
A glide distance calculator estimates how far an aircraft may travel horizontally from a given altitude if it glides at its approximate best glide ratio.
This is useful for emergency planning, forced landing awareness, training, and understanding aircraft glide performance in simple still-air terms.
Use altitude above ground level, not altitude above sea level, because glide distance planning depends on how much altitude is available above the terrain.
Use the approximate best glide ratio for your aircraft if known. If not, use a reasonable training estimate, but always refer to approved aircraft data when available.
Yes. A headwind reduces ground distance, while a tailwind increases it. This calculator gives a still-air estimate only.
No. This is a planning aid. Real glide performance depends on wind, aircraft configuration, speed control, terrain, and pilot technique.
