How to use this worksheet

  1. Print it, or save it as a PDF. Each problem gets a dotted work space. It fits on six Letter or A4 pages.
  2. Work on paper. Part A covers airfoils and the design lift coefficient, Part B thickness, aspect ratio, sweep and the planform, and Part C span loading, the wing's details, the tails and a whole wing. Each problem names the lesson to review if you get stuck.
  3. Check your final answers with Show answer under each problem, or show them all at once. Only final answers are given here.
