Preview Questions Avionics Technician | Role Specific Skill

Question 1: What is the first step when repairing an aircraft's environmental control system (ECS) sensors that are giving inaccurate readings?

Which action should you take?

Choose only one option

Replace the sensor and recheck the system functionality

Inspect the sensor wiring and connections for faults

Test the sensor for proper signal output

Recalibrate the sensor according to environmental factors

Question 2: When performing maintenance on an aircraft's communication system, what should be inspected first?

Which action should you take?

Choose only one option

Inspect the system settings without verifying physical components

Only check the headset volume settings

Check the antenna connections, verify the transceiver functionality, and inspect the wiring for continuity

Focus only on the power supply and ignore signal transmission

Question 3: In testing an aircraft's communication system, which parameter is most critical for ensuring accuracy?

Which action should you take?

Choose only one option

Frequency response, signal strength, and proper connection between transceivers and antennas

Visual inspection of the communication equipment

Checking only the volume levels and ignoring signal quality

Signal strength only, without checking the frequency response

Question 4: When calibrating an aircraft's transponder, what should be verified first?

Which action should you take?

Choose only one option

Check the visual display of the transponder only

Ignore the calibration settings and proceed to test the signal

Verify the power supply without checking frequency accuracy

Ensure the transponder's output frequency is correct and check the squawk code for accuracy

Question 5: When diagnosing and repairing a malfunction in an aircraft's primary flight display, what is the most common issue?

Which action should you take?

Choose only one option

Incorrect sensor readings due to calibration issues

Faulty connection or failure in the display unit's wiring

System software failure requiring a firmware update

Mechanical failure of the display screen

Question 6: When an aircraft's navigation system is providing erroneous data, what should be the first thing an avionics technician checks?

Which action should you take?

Choose only one option

Check the aircraft's airspeed sensor readings

Verify the accuracy of the aircraft's inertial navigation system (INS)

Inspect the aircraft's autopilot system for faults

Test the aircraft's electrical wiring for potential shorts
