just cause they do
If you mean fly on thermals like some gliders, NO.
Gliders can gain altitude when flying over a town due to thermals, which are pockets of warmer air that rise from the ground. When a glider encounters a thermal, it can circle within it to gain altitude, similar to how birds use thermals to soar without flapping their wings.
Thermals in the air are caused by the uneven heating of the Earth's surface, resulting in pockets of warm air rising and creating upward air currents. These thermals play a key role in the formation of clouds, precipitation, and can also influence the behavior of aircraft and gliders.
Yes, gliders have an airfoil very similar to that of a powered airplane. Gliders do generally have a wider wingspan in order to handle better at low-airspeed & therefore take better advantage of thermals or ridge-lift.
Soaring is basically the act of flying through the air without the aid of any propulsion(engine) and riding thermals(rising warm air) to get higher and higher into the air. Birds do it all the time. Also, there are aircraft that can achieve this type of flying. Gliders/Sailplanes as they're called are taken up to a certain altitude by a powered plane or winch, release and fly freely like a bird. Finding thermals will allow you to gain altitude and prolong the flight. Thermals are not always there though. This makes soaring very challenging.
The pixies(a little)
The Thermals was created in 2002.
Gliders achieve flight primarily through two methods: first, by being towed into the air by a powered aircraft, which provides the initial lift needed to reach altitude. Second, gliders can launch from a high point or hill using gravity, allowing them to glide down and gain altitude by utilizing rising air currents, such as thermals or ridge lift, to stay aloft.
They are called THERMALS. Check out http://www.gliding.co.uk/whatisgliding/soaring.htm for detailed information about these and other sources of lift used in soaring sailplanes (gliders).
thermals are used when cold
sugar gliders tend to have the same poch as a kangaroo
Gliders use thermals ( warm updrafts) to gain altitude, lift and Momentum- Flying over the stacks of a power house- assuming all stacks were (Up) one could gain about 500 feet of lift from each stack- or 2500 feet if you hit all five from the right angle! seagulls do the same thing, conserving their wing muscles. wait till the Public service has all Five stacks fired up and you can try the idea , not too close!
