What this calculator does
Calculates Aircraft Glide Range & Glide Ratio without Engine Power Sizer using the formula verified against the cited source.
What your result means
An estimate from the inputs you enter, within the scope stated below — not advice.
Formula
Glide distance = glide ratio × height (same units)
The step-by-step working for your own numbers appears with the result above and in the PDF report.

- • Assumes steady glide at the stated L/D, no wind and no additional altitude lost in turns/maneuvers. Ground range changes with wind; aircraft configuration, speed and propeller state affect L/D. Height must be above the landing site rather than simply altitude above sea level.
Important limitation
This is an educational estimate based only on the values and formula shown. Verify current rates, rules, units, and professional standards before relying on the result. It is not personalized financial or investment advice.
