Just about anyone can glide. In terms of medical requirements for solo flying, if you can drive a car you can fly a glider. Even if you can't drive a car you may be able to fly a glider: the minimum age for flying solo is 14. There is no fixed upper age limit. The weight limit is about 102 kg or 16 stone, and unusually tall or short people might not fit safely and/or comfortably in a glider.
For wheelchair users and those with other disabilities there is a flourishing club called Walking on Air which is based on our site and uses specially adapted gliders. Some medical conditions or medication would prevent solo flying but you might still be able to fly with a safety pilot. If you're uncertain whether you'd be able to fly just get in touch with us (see Contact).
