1. If you were going to design an airspeed system with no errors, what would it look like? How would you eliminate the errors?
2. Compare and contrast the methods of measuring aerodynamic forces in a wind tunnel to that of an airplane in flight.
3. Compare and contrast an aircraft having a high aspect ratio wing to an aircraft that has a low aspect wing. What are the operational requirements that drive these designs? All things being equal, which aircraft will--in principle--have longer endurance and why? Which aircraft will lose more energy in flight under elevated G and why?
