Glide ratio is directly related to glide path because it is a measure of how far forward we travel for every unit of vertical descent. Typical glide ratios for a paraglider are between 3 to 1 and 6 to 1. This means we travel between three feet forward for every foot of descent and six feet forward for every foot of descent depending on the design. 3, record 1, English, - glide%20ratio

La finesse d'un aérodyne à voilure fixe est le rapport, à une vitesse donnée, entre sa force portante (portance) et sa traînée aérodynamique. Elle est égale au rapport entre la distance horizontale parcourue et la hauteur initiale, à vitesse constante et sans force de propulsion, en air calme, ou encore au rapport entre la vitesse horizontale et le taux de chute. 2, record 1, French, - finesse
