Preview Questions Avionics Technician | Role Specific Skill

Question 1: When repairing a radar system in an aircraft, what component should you check first if the radar is not producing a clear image?

Which action should you take?

Choose only one option

The power supply to the radar system

The radar display for visual defects

The radar transmitter and receiver connections

The antenna alignment and integrity

Question 2: How should an avionics technician approach calibration for an aircraft's speed sensors?

Which action should you take?

Choose only one option

Ignore sensor accuracy and proceed with installation

Verify the sensor output against known velocity references and calibrate based on measured airspeed

Replace the sensors without performing a calibration check

Check only the sensor wiring and assume correct calibration

Question 3: How does the International Civil Aviation Organization (ICAO) affect avionics maintenance procedures?

Which action should you take?

Choose only one option

ICAO regulates avionics hardware installation

ICAO monitors the certification of avionics technicians

ICAO standards must be followed for international compliance

ICAO only provides guidelines for aircraft navigation systems

Question 4: When testing an aircraft's lighting system, which parameter is most critical for ensuring operational safety?

Which action should you take?

Choose only one option

Assume the system is working if the lights turn on

Ignore intensity settings and focus on physical installation only

Check only the visual appearance of the lights

Verify the power supply, check for correct color rendering, and confirm proper intensity settings for all lighting components

Question 5: During the installation of an aircraft's avionics system, what should be verified before turning on the system for the first time?

Which action should you take?

Choose only one option

Confirm that all sensors are calibrated

Ensure all wiring is properly routed and secured

Verify the system's ground connection and power supply

Check the system's software configuration

Question 6: What is the most common cause of calibration failure when testing an aircraft's temperature sensors?

Which action should you take?

Choose only one option

Excessive sensor exposure to heat or cold conditions

Interference from nearby electrical components

Incorrect sensor placement or wiring

Faulty calibration equipment or reference standards
