and Answers
"The internal pressure of a fluid decreases at point where the speed of the fluid
increases" is part of what principle
A. Bernoulli's Principle
B. Newton's law of motion
C. Hindenberg's Theory - Correct answer-A. Bernoulli's Principle
What is the primary source of lift? - Correct answer-Bernoulli's Principle
What is the secondary source of lift? - Correct answer-Newton's third law
Describe Newton's third law. - Correct answer-Upward force generated by air
striking the underside of an airfoil and being deflected downward.
What is relative wind? - Correct answer-Direction of airflow produced by object
moving through the air
What direction does relative wind flow? - Correct answer-Parallel with and
opposite to direction of flight

,Three main airfoils. - Correct answer-Wing, horizontal stabilizer, prop
What is the chord line? - Correct answer-imaginary line from the leading edge to
trailing edge of the wing.
What are the parts of an airfoil? - Correct answer-Leading edge, Trailing edge, and
Chord line
What is angle of attack? - Correct answer-angle between the chord line and relative
wind.
Describe camber - Correct answer-Curvature of an airfoil, from leading edge to the
trailing edge.

, What air is denser. Warm or cold? - Correct answer-Cold
Lower pressure is associated with what kind of air? - Correct answer-Thin, or less
dense air
Does High or Low density altitude indicate thinner air? - Correct answer-High
List some ways that performance is reduce by Higher density altitude, High temp,
and High elevation - Correct answer-Longer takeoff roll, Longer landing roll,
Slower climb rate, Landing speed increased.
