A human-powered aircraft has a gross weight of 240 lbf including the pilot. Its wing has a lift coefficient of 1.5 and a lift- to-drag ratio of 70. Estimate the wing area needed and the pilot power that must be provided for this craft to cruise at 15 mph. Assume that the wing profile drag is about 40 percent of the total drag and the propeller efficiency is 80 percent.
