PPL PPL Flight Instruments and Weather 2

Question 1

Which instrument relies on the pitot tube's ram air pressure to operate?

Accepted Answer

Airspeed indicator

Answer

The airspeed indicator measures the difference between ram (pitot) pressure and static pressure.

Question 2

If the static port becomes blocked in level flight, which instruments will be affected?

Accepted Answer

Airspeed, altimeter, and vertical speed indicator

Answer

The airspeed indicator, altimeter, and VSI all use the static system, so a static blockage affects all three.

Question 3

The attitude indicator, heading indicator, and turn coordinator are typically driven by what system in many training aircraft?

Accepted Answer

Vacuum (gyroscopic) system

Answer

These gyroscopic instruments are commonly powered by an engine-driven vacuum pump.

Question 4

During a coordinated turn, where should the ball in the turn coordinator be positioned?

Accepted Answer

Centered

Answer

A centered ball indicates coordinated flight with the correct balance of bank and rudder.

Question 5

What altitude does the altimeter display when set to the local altimeter setting on the ground?

Accepted Answer

Field elevation

Answer

With the current local setting, the altimeter should read the airport's field elevation.
