Without flaps or spoilers it is difficult to increase the steepness of the glide without adding significant speed. This excess speed can cause the aircraft to fly in ground effect for an extended period, perhaps running out of runway. In a forward slip much more drag is created, allowing the pilot to dissipate altitude without increasing ...
Speed range (stall speed – max speed) slowest – typically 25 to 60 km/h for recreational gliders (over 50 km/h requires use of speed bar), [16] hence easier to launch and fly in light winds; least wind penetration; pitch variation can be achieved with the controls faster than paragliders, slower than gliders/sailplaines
A variation of the yaw string is the side string, used in gliders for a determination of the angle of attack. In this way the speed for best glide angle, the best thermalling speed and the stall speed can be observed independently of other parameters like air speed, aircraft weight, acceleration due to turning, stick movements, and gusts.

Single-seat high performance fiberglass Glaser-Dirks DG-808 glider Aerobatic glider with tip smoke, pictured on July 2, 2005, in Lappeenranta, Finland. A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. [1]
The idea is to fly aircraft in the upward part of the wingtip vortex of a leading aircraft. [16] In 2003, NASA said one of its F/A-18 test aircraft had a 29% fuel savings by flying in the wingtip vortex of a DC-8. The DC-8/F-18 flight was an exploratory investigation of large aircraft vortex-induced performance benefits on a fighter-type aircraft.
The speed to fly is the optimum speed through sinking or rising air mass to achieve either the furthest glide, or fastest average cross-country speed. [1] Most speed to fly setups use units of either airspeed in kilometers per hour (km/h) and climb rate in meters per second (m/s), or airspeed in knots (kn) and climb rate in feet per minute (ft ...
It assumes a crab-like attitude relative to the wind. This is called a slip. The air is flowing crosswise over the fuselage. In order to correct this adverse slip, the pilot must apply rudder (right rudder in this example). If the pilot applies too much rudder, the airplane will then slip to the other side. This is called a skid.
Speed flying and speed riding are recreational and competitive adventure sports of flying lightweight, free-flying, foot-launched glider aircraft with no rigid primary structure. They are similar to sports to paragliding , but have smaller wings, higher flying speeds, and flightpaths descending close to a mountain slope.
