Aero 315 Final Pre-Flight Questions
with Detailed Verified Answers
Question: An aircraft pitches up or down by deflecting the _________which
generates a lifting force. Since this force is behind the center of gravity, it
causes the nose to pitch up or down. (32.2)
Answer: elevator
Question:
An aircraft rolls by deflecting the _________in opposite directions. Since one
wing now is generating more lift it creates a rolling moment. (32.2)
Answer: ailerons
Question:
An aircraft yaws by deflecting the _________which generates a force in the
side direction. Since this force is behind the center of gravity, it causes the
nose to yaw left or right. (32.2)
Answer: rudder
Question:
True or False. As an aircraft's static stability increases, its maneuverability
usually decreases. (32.4)
Answer: True

Question:
Which of the following is the correct definition of positive static stability?
(32.3)
Answer: Positive static stability is the initial tendency of a system to return to
equilibrium when disturbed.
Question:
Which of the following is the correct definition of positive dynamic stability?
(32.3)
Answer: Positive dynamic stability is the tendency over time of a system to
return to equilibrium when disturbed.
Question:
What does trimmed mean in the context of aircraft stability? (33.1)
Answer: The sum of the moments about the aircraft s center of gravity is zero
Question:
What is the neutral point? (33.9)
Answer: Location where if the center of gravity was co-located, it would yield
neutral stability AND The whole aircraft's aerodynamic center
Question:
If Static Margin (SM) is positive... (33.10)
