  1. (t/f) Lift is a force and therefore is measured in pounds
    true
  2. (t/f) AOA us defined as the actue angle formed by relative wind and the chord line
    true
  3. (t/f)increasing AOA increases induced drag
    true
  4. (t/f) increasing AOA decreases the velocity of the airflow over the wing
    false
  5. (t/f)Absolute zero is 32 degrees F
    false
  6. (t/f) to recover from an aerodynamic stall the pilot must immediately attempt to restart the engine
    false
  7. (t/f) the pressure of any fluid increases as depth increases
    true
  8. (t/f) Pressure is the same thing as density
    false
  9. (t/f) Otto Lilienthal was an early experimenter that invented the jet engine
    false
  10. (t/f) In the troposphere, temp and pressure decrease as altitude increase
    true
  11. (t/f) Otto Li. was the 1st person to cross the English Channel by balloon
    false
  12. (t/f) bernoulli's principle states that as velocity of a fluid increases the pressure increases as well
    false
  13. (t/f) A Venturi tube increases the velocity by decreasing cross sectional area
    true
  14. (t/f) a cambered airfoil acts as a venturi
    true
  15. (t/f) a stall is the result of flying at too low an airspeed
    false
  16. (t/f) temp is actually the amount of heat energy contained in any matter
    true
  17. (t/f) a cantilever wing has no external supports
    true
  18. (t/f) nearly 1/2 of the earth's atmosphere exists below 18,000ft
    false
  19. (t/f) water vapor is heavier and more dense than dry air
    false
  20. (t/f) a stall occurs when the airflow over the top of the wing is disrupted, life is reduced, and the force of weight takes over
    true
  21. (t/f) Absolute humidity is the amount of water vapor in the air compared to amount it could hold at that temp as a %
    false
  22. (t/f) the downwash force off the rear of the wing forces the wing upward
    true
  23. (t/f) thrust is measured in lbs
    true
  24. (t/f) the atmosphere is 78 % Ox, 21% Ni, 1% other
    FALSE
  25. HAPPY DAY :)
    btw you always get this one right <3
