Test on Aircraft Instruments and Systems

Question 1: Is the electrical bonding of an aircraft instrument panel to the primary aircraft structure primarily intended to protect instruments from lightning strikes?

A. Ano

B. Ne

Explanation: The bonding straps carry the return current from the instruments into the aircraft structure, which is the reason for electrically bonding the instrument panel to the primary aircraft structure.

Question 2: What component serves as the sensor within the fuel tank for an electronic-type fuel quantity indicating system?

A. A float-type rheostat

B. Tubular capacitors which extend across the fuel tank from top to bottom

C. A series of thermocouples

D. A current-measuring device

Explanation: The study materials state that tubular capacitors which extend across the fuel tank from top to bottom are used as the sensor in the fuel tank for an electronic-type fuel quantity indicating system.

Question 3: The Bourdon tube, the diaphragm, and bellows are fundamental pressure-sensing mechanisms used in aircraft instrument systems.

A. Ano

B. Ne

Explanation: The Bourdon tube, the diaphragm or bellows, and the solid-state sensing device are the three fundamental pressure-sensing mechanisms used in aircraft instrument systems.

Question 4: The takeoff warning system gives an aural warning when the power lever is advanced for takeoff if the flight controls for the stabilizer, the flaps, and the speed brakes are in an unsafe condition for takeoff.

A. Ano

B. Ne

Explanation: The takeoff warning system actuates when the power lever is advanced for takeoff if the stabilizer, the flaps, and the speed brakes are in an unsafe condition, issuing an aural warning.

Question 5: Based on the provided study materials, what is the function of an annunciator panel in an aircraft?

A. It serves as a single location for all the aircraft's warning and condition lights.

B. It displays the resistance of the bulb circuit for the pilot.

C. It makes it easy for the pilot to briefly monitor all aircraft systems.

D. It measures the pressure drop across the injector nozzles.

Explanation: The study materials state that an annunciator panel is 'A single location that contains all the warning and condition lights for the aircraft. This makes it easy for the pilot to monitor all the systems briefly.'
