- What happens to lift when the surface area of an airplane's
wings is increased?
_______________________________
- Open the Web page AirPage
Index (http://www.pilotportal.com/airpage/) and look up the
Boeing 747-100B. What is its wing
area?_________________________
- Refer to the above question. What is the Boeing 747's takeoff
weight?__________________
- How many passengers can the Boeing 747 carry?
______________________
- What is the ratio of the Boeing 747's takeoff weight to its
wing area? __________________

area? _______________
- If both the Boeing 777 and the DC-10 weighed 130,000 kg, which
airplane's wings would generate the most lift?

takeoff weight to wing area ratios? ________________________
- Explain the relationships among lift, takeoff weight, and wing
area. You may want to read the slide called Forces
on an Airplane.
