Junior Technician Interview Questions and Answers for Freshers

Resistance can be calculated using Ohm's Law, which states that resistance is equal to voltage divided by current.

• Use Ohm's Law: R = V / I

• Resistance is measured in ohms (Ω)

• Voltage is measured in volts (V)

• Current is measured in amperes (A)

• Example: If the voltage is 12V and the current is 2A, the resistance would be 6Ω

Aircraft fuelling involves a series of procedures and precautions to ensure safety and efficiency.

• Before fuelling, the aircraft must be properly grounded to prevent static electricity buildup.

• The fuel truck must be positioned correctly and securely connected to the aircraft's fuel system.

• The fuel type and quantity must be verified before starting the fuelling process.

• During fuelling, the fuel flow rate must be monitored to prevent overfilling or spillage.

• After fuelling, the f...read more

Color coding is used to identify the resistance value of a resistor.

• The first band represents the first digit of the resistance value.

• The second band represents the second digit of the resistance value.

• The third band represents the multiplier.

• The fourth band represents the tolerance.

• For example, a resistor with brown, black, red, and gold bands has a resistance value of 1.0 ohm with a tolerance of +/- 5%.

Aircraft transit procedure involves the movement of an aircraft from one location to another.

• The aircraft is inspected for any damages or issues before transit.

• The fuel and oil levels are checked and topped up if necessary.

• The cargo and baggage are loaded onto the aircraft.

• The passengers are boarded onto the aircraft.

• The pilot performs pre-flight checks and obtains clearance for takeoff.

• The aircraft is guided to the runway and takes off.

• During transit, the pilot communicates ...read more
