SACAA AME Instruments Practice Questions - SACAA Aircraft Maintenance Engineer Instrument General (CAT X & W) Theoretical Knowledge Examination Exam - SACAA AME Instruments Practice Questions - SACAA Aircraft Maintenance Engineer Instrument General (CAT X & W) Theoretical Knowledge Examination Exam

Question 1

In a basic aircraft pitot-static system, what pressure component is measured exclusively by the pitot tube opening during unaccelerated level flight?

Static pressure only Total pressure (static pressure plus dynamic pressure) Dynamic pressure only Differential cabin pressure

Correct Answer:

Total pressure (static pressure plus dynamic pressure)

Question 2

Where are static pressure ports typically mounted on an aircraft fuselage to minimize aerodynamic position error?

In the engine intake plenum where airflow velocity is highest Flush with the skin on both sides of the fuselage in an area of undisturbed airflow Directly behind the propeller arc on the upper nose cowling Inside the unpressurized wheel well bay

Correct Answer:

Flush with the skin on both sides of the fuselage in an area of undisturbed airflow

Question 3

If the pitot tube ram air inlet becomes completely blocked by ice while its drain hole remains OPEN, how will the Airspeed Indicator (ASI) react during a climb?

The ASI reading will drop to zero speed. The ASI will over-read, behaving like an altimeter. The ASI reading will freeze at the speed held prior to blockage. The ASI reading will fluctuate wildly around Vne.

Correct Answer:

The ASI reading will drop to zero speed.

Question 4

What happens to the Airspeed Indicator (ASI) indication if BOTH the pitot tube ram inlet and drain hole are completely frozen shut during an aircraft descent?

The ASI will under-read (indicate lower than true airspeed). The ASI will over-read (indicate higher than true airspeed). The ASI pointer will immediately fall to zero. The ASI pointer will lock firmly at the maximum scale reading.

Correct Answer:

The ASI will under-read (indicate lower than true airspeed).

Question 5

If the primary static line becomes completely blocked during flight, how will the Altimeter, Vertical Speed Indicator (VSI), and Airspeed Indicator (ASI) behave during a climb?

Altimeter freezes; VSI reads zero; ASI under-reads. Altimeter over-reads; VSI indicates maximum climb rate; ASI over-reads. Altimeter freezes; VSI indicates maximum descent rate; ASI reads zero. Altimeter under-reads; VSI freezes at last rate; ASI functions normally.

Correct Answer:

Altimeter freezes; VSI reads zero; ASI under-reads.
