Which flight instrument is powered by the pitot-static system?
Answer: Airspeed indicator
The airspeed indicator uses the difference between pitot (ram) pressure and static pressure to display indicated airspeed.
What does the VSI (Vertical Speed Indicator) display?
Answer: Rate of change of altitude in feet per minute
The VSI measures the rate of change in static pressure to display climb or descent rate in feet per minute.
Which gyroscopic instrument is MOST susceptible to precession error?
Answer: Heading indicator
The heading indicator (directional gyro) is most susceptible to precession and must be periodically realigned with the magnetic compass.
What is the purpose of the carburetor heat system?
Answer: Prevent or eliminate carburetor ice by routing warm air to the carburetor
Carburetor heat routes warm air from around the exhaust manifold into the carburetor to melt ice or prevent its formation.
What does a 'rich' mixture setting mean in a piston engine?
Answer: More fuel relative to stoichiometric air-fuel ratio
A rich mixture contains more fuel than the chemically ideal ratio, which provides engine cooling but reduces fuel efficiency.
The altimeter is set to the local altimeter setting. What does it then display?
Answer: Indicated altitude, which approximates MSL altitude in standard conditions
With the correct altimeter setting, the altimeter displays indicated altitude, which closely approximates MSL altitude under standard temperature conditions.
