Our default is 10:1; most aircraft fall between 6:1 and 14:1. A fuselage crosses the hole. Modern gliders can have glide ratios better than 60:1. The glide ratio is the distance travelled in a horizontal direction compared with the vertical distance dropped on a normal glide. The only effect weight has is to vary the time the aircraft will glide for. A higher aspect ratio gives a lower drag, a higher lift to drag ratio, and a better glide angle. Graphed examples of Glide Slope Ratios and their interpretations: Glide Slope “A” would represent a good Glide-Slope Ratio Distance = 20 ft. Altitude = 10 ft. Gliders have a high aspect ratio because the drag of the aircraft depends on this parameter. It looks like a flying pancake but with a hole in the middle. The aspect ratio is used when calculating the aerodynamic efficiency of the wing of a plane. Distance (20) divided by Altitude (10) = 2/1 = Glide Ratio of 2.0 The glider flew forward two feet for every one-foot drop in altitude. I am going to assume that you are referring to a wing design that allows you to travel the longest possible distance before you hit the ground when launched from a given altitude.
The first low aspect ratio's I heard of are the annular experiments of Lee-Richards in 1911-1914. The aspect ratio is used when calculating the aerodynamic efficiency of the wing of a plane.

A 767-200 has an aspect ratio of 8~, along with a glide ratio of (according to Wikipedia) 12:1. The glide ratio is based only on the relationship of the aerodynamic forces acting on the aircraft.
For comparison, a commercial jetliner might have glide ratios somewhere around 17:1. For a standard wing area, the function A(s) – 36 can be used to find the aspect ratio depending on the wingspan in feet. Now, enough about gliders! For a rectangular wing, this reduces to the ratio of the span to the chord length (c): High aspect ratio wings have long spans (like high performance gliders), while low aspect ratio wings have either … Low aspect ratio wings such as seen on the famous “Leprechaun” glider definitely are good for floating, but when it comes to maximum soaring efficiency the top sailplane designers of the world certainly don’t consider low aspect ratios as even starting to compete. So if the wing span is 30 feet and the cord is 6 feet, then the aspect ratio is 5. How can a designer maximize the glide ratio of an aircraft with low aspect ratio wings, other than by increasing the aspect ratio? This means they can glide for 60 miles if they start at an altitude of one mile. Aspect Ratio is calculated as the square of the wingspan of a glider divided by the surface area of the wing. For comparison, a commercial jetliner might have glide ratios … This ratio tells you how much horizontal distance a glider can travel compared to the altitude it has to drop. Distance (20) divided by Altitude (10) = 2/1 = Glide Ratio of 2.0 The glider flew forward two feet for every one-foot drop in altitude. HpH 304 is a family of sailplanes ranging from a single-seat composite 15 metre Class to a two-place 20 metre Open Class manufactured by the Czech company HpH Ltd.The sailplane was derived from a glider made by Glasflügel between 1980 and 1982 that was put back in production by HpH and who have modified it substantially and developed new models since. (A glide ratio of 20:1 might be appropriate for an Eagle riding the wind while a 1:14 ratio is similar to the glide capability of a brick.) Aspect Ratio effects glider performance and characteristics more than any other factor. In other words, the aircraft will glide horizontally 8 units for every 1 unit of descent. The aspect ratio is calculated as: 9.6 2 / 16.2 = 5.7 Or in imperial units: 31.5 2 / 174 = 5.7 Graphed examples of Glide Slope Ratios and their interpretations: Glide Slope “A” would represent a good Glide-Slope Ratio Distance = 20 ft. Altitude = 10 ft. Active 15 days ago.
