What does a red arc on an airspeed indicator represent?
Answer: Never-exceed speed (VNE)
The red line marks VNE, the never-exceed speed.
The white arc on the airspeed indicator represents the:
Answer: Flap operating range
The white arc is the flap operating range, from VS0 to VFE.
Which instrument operates on the pitot-static system alone?
Answer: Airspeed indicator
The airspeed indicator uses both pitot (ram) and static pressure.
If the pitot tube becomes blocked but the static port remains clear, the airspeed indicator will:
Answer: Act like an altimeter during climbs and descents
A blocked pitot tube with a clear static port makes the airspeed indicator behave like an altimeter.
The attitude indicator, heading indicator, and turn coordinator most commonly rely on:
Answer: Gyroscopic principles
These are gyroscopic instruments driven by rigidity in space and precession.
During which condition does the magnetic compass read most accurately?
Answer: In straight-and-level, unaccelerated flight
The magnetic compass is accurate only in straight-and-level, unaccelerated flight.
What error occurs when accelerating on an east or west heading (in the Northern Hemisphere)?
Answer: The compass shows a turn to the north
Acceleration on east/west headings causes the compass to indicate a turn toward north (remember ANDS).
