Top 10 Questions for Avionics Systems Repairer Interview

1. What is the procedure to perform a continuity test on an electrical circuit?

The procedure to perform a continuity test on an electrical circuit is as follows:

• Turn off the power to the circuit.
• Set the multimeter to the continuity setting.
• Touch the probes of the multimeter to the two points in the circuit that you want to test.
• If the multimeter beeps, then the circuit is continuous. If the multimeter does not beep, then the circuit is not continuous.

2. How would you troubleshoot a faulty printed circuit board (PCB)?

Steps to troubleshoot a faulty PCB:

• Visually inspect the PCB for any obvious damage, such as burnt components or broken traces.
• Use a multimeter to test the continuity of the traces and the components on the PCB.
• Use a logic probe to test the logic signals on the PCB.
• Replace any faulty components or traces.

Tips for troubleshooting a faulty PCB:

• Start by testing the most likely causes of the problem.
• Be systematic in your troubleshooting approach.
• Document your troubleshooting steps.
• Don’t be afraid to ask for help from a more experienced technician.

3. What is the difference between analog and digital signals?

• Analog signals are continuous, while digital signals are discrete.
• Analog signals can take on any value within a certain range, while digital signals can only take on certain discrete values.
• Analog signals are typically used to represent continuous data, such as audio or video signals, while digital signals are typically used to represent discrete data, such as computer data.

4. What is the purpose of a capacitor in an electrical circuit?

• Capacitors store electrical energy.
• Capacitors can be used to filter out noise from a signal.
• Capacitors can be used to store energy for a later time.
• Capacitors can be used to create resonant circuits.

5. What is the difference between a diode and a transistor?

• Diodes allow current to flow in only one direction, while transistors can amplify or switch signals.
• Diodes are made of two layers of semiconductor material, while transistors are made of three layers of semiconductor material.
• Diodes are used in a variety of applications, such as rectifiers, voltage regulators, and logic gates, while transistors are used in a variety of applications, such as amplifiers, switches, and logic gates.

6. What is the purpose of a transformer in an electrical circuit?

• Transformers are used to change the voltage or current of an AC signal.
• Transformers can be used to isolate two circuits from each other.
• Transformers can be used to change the impedance of a circuit.
• Transformers are used in a variety of applications, such as power distribution, audio amplification, and electronic isolation.

7. What is the difference between a fuse and a circuit breaker?

• Fuses are one-time-use devices that protect circuits from overcurrent.
• Circuit breakers are reusable devices that protect circuits from overcurrent.
• Fuses are typically used in low-voltage applications, while circuit breakers are typically used in high-voltage applications.
• Fuses are less expensive than circuit breakers, but circuit breakers are more reliable.

8. What is the difference between a single-phase and a three-phase electrical system?

• Single-phase systems have one voltage waveform, while three-phase systems have three voltage waveforms.
• Single-phase systems are typically used in residential and commercial applications, while three-phase systems are typically used in industrial applications.
• Three-phase systems can provide more power than single-phase systems.
• Three-phase systems are more efficient than single-phase systems.

9. What is the purpose of a ground wire in an electrical circuit?

• Ground wires provide a low-resistance path to ground for fault currents.
• Ground wires help to protect people from electrical shock.
• Ground wires help to protect equipment from damage.
• Ground wires are required by electrical codes in most countries.

10. What is the difference between a conductor and an insulator?

• Conductors allow electricity to flow through them easily, while insulators do not.
• Conductors are typically made of metals, while insulators are typically made of plastics or ceramics.
• Conductors are used in a variety of applications, such as wires, cables, and busbars, while insulators are used in a variety of applications, such as electrical tape, circuit boards, and insulators.
