-
(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
