Ultralight Airplanes An ultralight air is very different from a conventional airplane.It looks like a lawn chair with wings,weighs no more than 254 pounds,flies up to 60 miles an hour,and carries about 5 gallons of fuel.Most ultralights are sold as kits and take about 40 hours to assemble. Flying an ultralight it so easy that a pilot with no experience can fly one. Accidents are rarely fatal or even serious because the ultralight lands so slowly and gently and carries so little fuel. Some models now have parachutes attached,while others have parachute packs which pilots can wear
