gliding ratio
1Gliding — is a recreational activity and competitive sport in which pilots fly un powered aircraft known as gliders or sailplanes. Properly, the term gliding refers to descending flight of a heavier than air craft, whereas soaring is the correct term to… …
2gliding speed — The speed at which an aircraft glides. It must glide at the angle of attack at which the lift/drag (L/D) ratio is maximized to obtain the best glide angle and the maximum gliding distance. The best gliding speed corresponds to this angle of… …
3glide ratio — The ratio of the forward distance traveled to the vertical distance an aircraft descends when gliding without any power. Also called a gliding ratio …

5History of hang gliding — Hang gliding is an air sport employing a foot launchable aircraft known as a hang glider. Typically, hang gliders are composed of an aluminium or composite framed fabric wing. The pilot is ensconced in a harness depending from the airframe, and… …
6Glide ratio — Glide ratio, also called, Lift to drag ratio, glide number, or finesse, is an aviation term that refers to the distance an aircraft will move forward for any given amount of lost altitude (the cotangent of the downward angle). Alternatively it is …
7Flying and gliding animals — A number of animals have evolved aerial locomotion, either by powered flight or by gliding. Flying and gliding animals have evolved separately many times, without any single ancestor. Flight has evolved at least four times, in the insects,… …
8Glider — Gliders or Sailplanes are heavier than air aircraft primarily intended for unpowered flight. See also gliding and motor gliders for more details. [cite web url = http://www.ssa.org/UsTeam/adobe%20pdf/pr%20pdf/BR%20Sailplanes%20V3%2004.pdf title …
9Kite types — Colorful delta wing kite Kites are tethered flying objects which fly by using aerodynamic lift, requiring wind, (or towing), for generation of airflow over the lifting surfaces. Contents 1 Kite …
10Bird flight — Flight is the main mode of locomotion used by most of the world s bird species. Flight assists birds while feeding, breeding and avoiding predators.Evolution of bird flightMost paleontologists agree that birds evolved from small theropod… …
