# theory of Flight Exam 1

 (t/f) Lift is a force and therefore is measured in pounds true (t/f) AOA us defined as the actue angle formed by relative wind and the chord line true (t/f)increasing AOA increases induced drag true (t/f) increasing AOA decreases the velocity of the airflow over the wing false (t/f)Absolute zero is 32 degrees F false (t/f) to recover from an aerodynamic stall the pilot must immediately attempt to restart the engine false (t/f) the pressure of any fluid increases as depth increases true (t/f) Pressure is the same thing as density false (t/f) Otto Lilienthal was an early experimenter that invented the jet engine false (t/f) In the troposphere, temp and pressure decrease as altitude increase true (t/f) Otto Li. was the 1st person to cross the English Channel by balloon false (t/f) bernoulli's principle states that as velocity of a fluid increases the pressure increases as well false (t/f) A Venturi tube increases the velocity by decreasing cross sectional area true (t/f) a cambered airfoil acts as a venturi true (t/f) a stall is the result of flying at too low an airspeed false (t/f) temp is actually the amount of heat energy contained in any matter true (t/f) a cantilever wing has no external supports true (t/f) nearly 1/2 of the earth's atmosphere exists below 18,000ft false (t/f) water vapor is heavier and more dense than dry air false (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 (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 (t/f) the downwash force off the rear of the wing forces the wing upward true (t/f) thrust is measured in lbs true (t/f) the atmosphere is 78 % Ox, 21% Ni, 1% other FALSE HAPPY DAY :) btw you always get this one right <3 Authorapscott92 ID53312 Card Settheory of Flight Exam 1 Descriptiontheory Updated2010-12-13T01:08:32Z Show Answers
