Almost everyone with a disability can glide with Walking on Air, from teenagers onwards.
In terms of medical requirements, as a guide, if you can drive a car you can fly a glider. Even if you can't drive a car you may still 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 100 kg or 16 stone, and unusually tall or short people might not fit safely and/or comfortably in a glider.
Some medical conditions or medication prevent solo flying but you might still be able to fly with an instructor. If you're uncertain whether you'd be able to fly just get in touch with us.
