Who can fly a glider?
Just about anybody can learn how to fly a glider. Some will learn faster than others, but if you are of normal fitness, less than say 16 stone, not over 6ft 4ins and old enough to accept tuition then you can fly a glider.
Young people can start at a surprisingly early age, minimum weight is more of an issue so this probably means a lower age limit of around 12/13. In the UK, it’s permissible for pilots as young as 14 to fly solo.
Many people take up gliding relatively late in life, some returning after tasting gliding when younger, perhaps in the Air Cadets or Scouts!
