Brunei DCA CPL(A) Instrumentation Practice Questions - Brunei DCA CPL(A) Theoretical Knowledge - Aircraft General Knowledge Instrumentation Exam - Brunei DCA CPL(A) Instrumentation Practice Questions - Brunei DCA CPL(A) Theoretical Knowledge - Aircraft General Knowledge Instrumentation Exam

Question 1

What is the primary operating principle of an aneroid altimeter in an aircraft pitot-static system?

It measures dynamic pressure changes relative to total pressure It measures ambient static atmospheric pressure using an evacuated sealed capsule It calculates altitude by comparing pitot impact pressure against cabin pressure It senses temperature lapse rates to determine geometric altitude

Correct Answer:

It measures ambient static atmospheric pressure using an evacuated sealed capsule

Question 2

How is Calibrated Airspeed (CAS) defined in relation to Indicated Airspeed (IAS)?

IAS corrected for instrument error and position (pressure location) error IAS corrected for air density variations at non-standard temperatures CAS is the speed of the aircraft relative to the speed of sound at sea level IAS corrected for adiabatic compressibility at high Mach numbers

Correct Answer:

IAS corrected for instrument error and position (pressure location) error

Question 3

What internal mechanism enables a Vertical Speed Indicator (VSI) to measure rate of climb or descent?

A pitot-static dual diaphragm connected to a gyroscopic rate sensor A flexible diaphragm inside a case, equipped with a calibrated metering leak An electronic pressure transducer measuring total temperature variations A sealed aneroid capsule expanding against an internal vacuum

Correct Answer:

A flexible diaphragm inside a case, equipped with a calibrated metering leak

Question 4

When an altimeter subscale is set to QNH, what altitude indication will the instrument display on the ground at an airfield?

Zero feet above the airfield runway threshold The official airfield elevation above mean sea level (MSL) The pressure altitude referenced to the 1013.25 hPa standard datum The height of the aircraft above terrain directly below

Correct Answer:

The official airfield elevation above mean sea level (MSL)

Question 5

How is Mach Number defined in high-speed flight aerodynamics?

The ratio of Calibrated Airspeed (CAS) to the local speed of sound The ratio of True Airspeed (TAS) to the local speed of sound The ratio of Equivalent Airspeed (EAS) to the sea-level speed of sound The ratio of Indicated Airspeed (IAS) to the speed of sound at standard temperature

Correct Answer:

The ratio of True Airspeed (TAS) to the local speed of sound
