Flight Instruments QZ1

Question 1

Which instrument(s) will become inoperative if the static vents become clogged?
1. Airspeed indicator only.
2. Altimeter only.
3. Airspeed indicator, altimeter, and vertical speed indicator.

Answer 1

3. Airspeed indicator, altimeter, and vertical speed indicator.

Explanation: If the pitot tube and static port both become plugged, then all three pitot static instruments will be affected.

Question 2

If the pitot tube and outside static vents become clogged, which instruments would be affected?
1. The altimeter, airspeed indicator, and vertical speed indicator.
2. The altimeter, attitude indicator, and turn-and-slip indicator.
3. The altimeter, airspeed indicator, and turn-and-slip indicator.

Answer 2

1. The altimeter, airspeed indicator, and vertical speed indicator.

Explanation: If the pitot tube and static port both become plugged, then all three pitot static instruments will be affected.

Question 3

(PAR-FI1-21) (Refer to Figure 4.) What is the caution range of the airplane (yellow arc)?
1. 100 to 165 kts.
2. 165 to 208 kts.
3. 0 to 60 kts.

Answer 3

2. 165 to 208 kts.

Question 4

Which instrument will become inoperative if the pitot tube becomes clogged?
1. Airspeed indicator.
2. Altimeter.
3. Vertical speed indicator.

Answer 4

1. Airspeed indicator.

Explanation: The only instrument that uses pressure from the pitot tube is the airspeed indicator, so the only instrument affected if the pitot tube becomes clogged is the airspeed indicator.

Question 5

The pitot system provides impact pressure for which instrument?
1. Altimeter.
2. Vertical-speed indicator.
3. Airspeed indicator.

Answer 5

3. Airspeed Indicator

Explanation: The only instrument that uses impact pressure is the airspeed indicator.

Question 6

As altitude increases, the indicated airspeed at which a given airplane stalls in a particular configuration will
1. Decrease as the true airspeed increases.
2. Remain the same regardless of altitude.
3. Decrease as the true airspeed decreases.

Answer 6

2. Remain the same regardless of altitude.

Explanation: While true airspeed may increase, the indicated airspeed will remain the same. The airfoil will always stall at the same angle of attack, regardless of airspeed.

Question 7

(PAR-FI1-22) (Refer to Figure 4.) The maximum speed at which the airplane can be operated in smooth air is
1. 165 kts.
2. 100 kts.
3. 208 kts.

Answer 7

3. 208 kts.
