The Glide Ratio is the ratio of distance forward to distance downwards when a glider is flown at a constant speed in still air. The glide ratio varies with air speed, but there is a maximum value which is frequently quoted. Glide ratio usually varies little with vehicle load; a heavier vehicle glides faster, but nearly maintains its glide ratio.

The following formula is used: epsilon=(DeltaS)/(DeltaH), where:

• DeltaS = distance of forward travel
• DeltaH = altitude lost in forward travel
