Polar curve showing glide angle for the best glide speed (best L/D). It is the flattest possible glide angle through calm air, which will maximize the distance flown. This airspeed (vertical line) corresponds to the tangent point of a line starting from the origin of the graph.
open class sailplanes – typically around 60:1, but in more common 15–18 meter span aircraft, glide ratios are between 38:1 and 52:1; [21] high glide performance enabling long distance flight, with 3,000 kilometres (1,900 mi) being current (as of November 2010) record [22]
Emission patterns of the localizer and glide slope signals Glide slope station for runway 09R at Hannover Airport in Germany. In aviation, instrument landing system glide path, commonly referred to as a glide path (G/P) or glide slope (G/S), is "a system of vertical guidance embodied in the instrument landing system which indicates the vertical deviation of the aircraft from its optimum path ...
Thirteen minutes later, at 06:26 UTC and about 65 nautical miles (120 km; 75 mi) from Lajes Air Base, engine no. 1 also flamed out, requiring the plane to glide the remaining distance. [3]: 8 Without engine power, the plane lost its primary source of electrical power.
Pilots need some form of control over the glide slope to land the glider. In powered aircraft, this is done by reducing engine thrust. In gliders, other methods are used to either reduce the lift generated by the wing, increase the drag of the entire glider, or both. Glide slope is the distance traveled for each unit of height lost. In a steady ...

A 90° approach calls for the throttle to be closed when the aircraft is angled 45° from centerline. [3] On Base leg, the airspeed needs to be lowered to the manufacturer's recommended glide speed. In order to stretch the gliding distance, pilots will often pitch up momentarily to attain best glide speed, also known as Vg. Once this speed is ...
One of the measures of a glider's performance is the distance that it can fly for each meter it descends, known as its glide ratio. Glide ratio is dependent on an aircraft's class, and can typically range from 44:1 (for modern designs in the Standard Class) up to 70:1 (for the largest aircraft).
