Preview Questions Avionics Technician | Role Specific Skill

Question 1: During the installation of a GPS system in an aircraft, what must be done to ensure proper functionality?

Which action should you take?

Choose only one option

Install the GPS system without checking the antenna placement

Verify the antenna location, check the wiring for proper continuity, and calibrate the system with a known reference

Assume the system will work once the wires are connected

Only check the wiring and ignore the antenna alignment

Question 2: How does the "Calibrating of VOR and ILS Systems" (VHF Omnidirectional Range and Instrument Landing System) improve avionics system accuracy?

Which action should you take?

Choose only one option

It increases the system's transmission range

It improves the antenna reception for communication signals

It adjusts the aircraft's autopilot function during flight

It ensures accurate navigation and approach guidance by aligning the system's signal to predefined standards

Question 3: When troubleshooting a malfunctioning aircraft radar system, what component should you inspect if there is no radar return signal?

Which action should you take?

Choose only one option

The radar's software and settings

The aircraft's electrical power supply

The radar receiver and antenna connections

The radar's frequency settings

Question 4: In avionics troubleshooting, what does the failure of a "Flight Data Acquisition Unit" (FDAU) indicate about the aircraft's system?

Which action should you take?

Choose only one option

It is usually due to insufficient airflow in the cabin, unrelated to avionics

It points to a fuel system malfunction unrelated to avionics

It indicates a problem with the collection and transmission of critical flight data, requiring immediate inspection

It suggests a minor issue with power distribution in the aircraft

Question 5: How do you handle troubleshooting the aircraft's emergency locator transmitter (ELT) system?

Which action should you take?

Choose only one option

Skip the testing phase and proceed to replacement

Inspect the ELT battery, verify its activation mechanism, and test the signal transmission

Test the transmitter signal without inspecting the wiring

Ignore the battery and only check the signal

Question 6: What is the role of "Software Updates" in the troubleshooting and maintenance of avionics systems post-installation?

Which action should you take?

Choose only one option

Software updates ensure that avionics systems run the latest versions, improving performance and fixing bugs that affect functionality

Software updates are required only for non-critical avionics systems

Software updates are irrelevant for avionics systems once installed

Software updates only improve the physical display quality
