Aircraft Instrumentation Quiz

The airspeed indicator is showing 0 airspeed even though the plane is in motion. All the other instruments on the aircraft appear to be functioning normally. The pilot suspects a pitot-static malfunction. What might be the problem?

• Ram air port blockage

• Drain hole blockage

• Static port blockage

• Both ram port and drain hole blockage

A pilot’s VSI shows the following. What is the vertical speed of the aircraft?

• 0.6 ft/min climb

• 600 ft/min climb

• 0.6 ft/min descent

• 600 ft/min descent

How does a gyroscope respond to a deflective force when it is powered?

• It moves in the direction of deflection and the deflection occurs 90 degrees in the direction of rotation from the point at which the force is applied.

• It moves in the direction of deflection and the deflection occurs 90 degrees opposite the direction of rotation from the point at which the force is applied.

• It moves opposite the direction of deflection and the deflection occurs 90 degrees in the direction of rotation from the point at which the force is applied.

• It moves opposite the direction of deflection and the deflection occurs 90 degrees opposite the direction of rotation from the point at which the force is applied.

What does the white arc on the airspeed indicator indicate?

• The safe operating range for the flaps

• The maximum speed with flaps extended

• The normal operating range of the aircraft

• The power-off stall speed at maximum takeoff weight

What information is processed by the air data computer (ADC)?

• Information from gyroscopic instruments

• Information about direction and heading

• Information about static and ram pressure

• None; it is used to store information collected during flight.

How is the groundspeed of an aircraft calculated?

• Headwinds are added and tailwinds are subtracted from the true air speed

• Tailwinds are added and headwinds are subtracted from the true air speed

• Headwinds are added and tailwinds are subtracted from the calibrated air speed

• Tailwinds are added and headwinds are subtracted from the calibrated air speed

What information is provided on a compass correction card?

• The amount of adjustment required to correct for northerly turning error

• The amount of adjustment required to correct for magnetic deviation

• The amount of adjustment required to correct for magnetic variation

• The amount of adjustment required to correct for acceleration error

How should a pilot adjust their altimeter before takeoff if operating at an airport where no altimeter setting is provided?

• The altimeter should be adjusted until it displays 0.

• The altimeter should be adjusted until it displays the airport’s elevation.

• The altimeter should be adjusted until it displays the elevation at sea level.

• The altimeter should be adjusted until it displays the lowest possible elevation.

An aircraft’s static port is blocked but the ram air port and the drain hole remain unobstructed. What instruments would become unreliable? Select all that apply.

• Vertical speed indicator

• Airspeed indicator

• Heading indicator

• Altimeter

• Attitude indicator

A pilot is turning the plane north. Which of these guidelines should they follow?

• The pilot should stop the turn after the desired heading because the compass leads the turn

• The pilot should stop the turn before the desired heading because the compass leads the turn

• The pilot should stop the turn after the desired heading because the compass lags the turn

• The pilot should stop the turn before the desired heading because the compass lags the turn
