What does the term 'angle of attack' refer to in aviation?
Answer: The angle between the wing chord line and the relative wind
Angle of attack is the angle between the chord line of the wing and the direction of the oncoming relative wind.
Which instrument measures an aircraft's altitude by sensing atmospheric pressure?
Answer: Altimeter
The altimeter measures altitude by detecting changes in static atmospheric pressure, which decreases as altitude increases.
What is the primary purpose of an aircraft's rudder?
Answer: Control yaw
The rudder is a vertical control surface on the tail that controls yaw, rotating the aircraft around its vertical axis.
In nautical terminology, what does 'port' refer to?
Answer: The left side of a vessel
Port refers to the left side of a vessel when facing forward; starboard is the right side.
What causes an aircraft to stall?
Answer: Exceeding the critical angle of attack
A stall occurs when the wing exceeds the critical angle of attack, causing airflow to separate and lift to decrease dramatically.
What is the standard atmospheric pressure at sea level in the US?
Answer: 29.92 inches of mercury
Standard sea-level atmospheric pressure is 29.92 inches of mercury (1013.25 millibars), used as the baseline for altimeter settings.
