Sailplanes
These aircraft use the wind and rising columns of warm air for lift. Like birds, they can soar for great distances and to great heights.
SAILPLANE - An unpowered, soaring aircraft capable of maintaining level flight for long periods of time after release from tow and of gaining altitude using wind currents, as opposed to a GLIDER.
Sailplane: A high performance glider capable of soaring flight.
Sandstorm: A wind laden with sand or dust which may cover a large area and reduce visibility. Sandstorms frequently held up air operations in the Second World War in North Africa.

The gull wing was first seen on a glider when the Weltensegler flew in 1921. Its wings were externally braced and featured swept-back wingtips.
SAILPLANE - An unpowered heavier-than-air craft designed primarily for soaring flight.
SEAPLANE - A heavier-than-air craft which operates from water, and is supported on the surface of the water by floats.

A high performance sailplane wing, designed for minimum induced drag over the CL range, might have a wingspan of 22 m and an aspect ratio of 30 thus a mean chord of 0.7 m. Most ultralights would have an aspect ratio between 5.
It was on October 3, 2006, that I took my first lesson in a sailplane (glider).
In the fifties this was dramatically shown in a photograph of the top of a sailplane wing (in-flight) that had dew on it. A few tiny seeds had landed on forward area the wing while on the ground.
The SGS 2-33 is a conventional two-place tandem, intermediate-training sailplane, manufactured by Schweizer Aircraft Corp., Elmira, New York. Its construction is all-metal with fabric cover on the fuselage and tall surfaces.
In addition, Cole has participated in a variety of sailplane and other experimental aircraft projects.
Typically, more dihedral causes more aerodynamic stability in an airplane, and causes the rudder to control both the roll and yaw axis. This is why some trainers and sailplanes require only 3 channels of radio control-i.e., having no ailerons.
