How do you gain altitude in a glider?
If the pilot can locate a pocket of air that is rising faster than the glider is descending, the glider can actually gain altitude, increasing its potential energy. Pockets of rising air are called updrafts. Updrafts are found when a wind blowing at a hill or mountain has to rise to climb over it.
What is the glider’s weight affected by?
The weight acts through the center of gravity and is always directed towards the center of the earth. The magnitude of the weight is given by the weight equation and depends on the mass of the vehicle plus its payload. The lift and drag are aerodynamic forces and act through the center of pressure.
What are gliders made out of?
Gliders were mainly built of wood and metal but the majority now have composite materials using glass, carbon fibre and aramid fibers. To minimise drag, these types have a fuselage and long narrow wings, i.e. a high aspect ratio.
What do air brakes on a glider do?
The airbrake’s primary effect is to create variable amounts of extra drag, which comprises profile drag and induced drag in proportions dependent on the glider’s speed. The extra drag increases the vertical rate of descent and worsens the glide ratio.
Is the G109B a self-launching motor glider?
Under the current CAA LASORS document, the G109B can be classed as either a touring motor glider (TMG), or a self-launching motor glider (SLMG). Royal Air Force Vigilant T.1 lands at RIAT 2008, England.
Who are the staff of a Volunteer Gliding Squadron?
Staff of a Volunteer Gliding Squadron are part-time personnel (usually specifically appointed Reserve Officers and civilians), supernumerary personnel (who are either regular or reservist members of the Armed Forces or Cadet Force Volunteers), and Flight Staff Cadets.
What happened to the Air Cadet gliding and flying program?
In March 2016, a major restructuring of Air Cadet Gliding and Flying was announced, resulting in the disbanding of 14 VGSs, significant reduction of the Vigilant, a regional focus of remaining Viking squadrons, and an increase in Tutor AEF flying.
