Preview Questions Avionics Technician | Role Specific Skill

Question 1: When diagnosing an issue with an aircraft's landing gear indicator system, what is the first check to perform?

Which action should you take?

Choose only one option

Check only the sensor alignment without verifying power supply

Focus on the wiring and ignore the sensor calibration

Inspect the wiring connections, check the sensors, and verify the power supply

Only check the display panel without verifying the sensors

Question 2: When installing avionics equipment in an aircraft, which standard must be adhered to for ensuring electrical safety?

Which action should you take?

Choose only one option

Follow internal company procedures without considering external standards

Only adhere to basic safety protocols without reference to industry standards

Skip electrical safety checks to speed up installation

Ensure compliance with FAA regulations, specifically RTCA DO-160 for environmental conditions

Question 3: In avionics troubleshooting, how do "Circuit Breakers" protect avionics systems from electrical failures?

Which action should you take?

Choose only one option

Circuit breakers only affect lighting systems, not avionics

Circuit breakers are used to regulate air pressure in avionics units

Circuit breakers automatically disconnect power when electrical faults are detected, preventing damage to sensitive avionics components

Circuit breakers monitor engine speed and throttle functions

Question 4: In avionics maintenance, what does "FAA Certification" ensure when it comes to safety compliance and operational standards?

Which action should you take?

Choose only one option

It certifies the aesthetic aspects of avionics systems

It focuses solely on weight distribution in avionics components

It only applies to military aircraft, not commercial ones

It ensures that avionics systems meet stringent safety, reliability, and performance standards for commercial aviation

Question 5: In troubleshooting an avionics system, what is the first step if you detect intermittent electrical failure in the power supply?

Which action should you take?

Choose only one option

Replace all power supply components immediately

Check for loose connections or damaged wiring that could be causing the electrical interruptions

Inspect only the external power source without verifying internal wiring

Reboot the system and monitor for issues

Question 6: When installing a new radar system, why is it critical to perform "System Alignment" and "Calibration" after installation?

Which action should you take?

Choose only one option

It helps in reducing the size of the radar system

It is only needed for high-end military radar systems, not civilian ones

It ensures that the radar system is accurately detecting targets and displaying correct data to the operator

It is only necessary for aesthetic purposes to match system displays
