Air India Aircraft Maintenance Technician Interview Questions and Answers

Angle of incidence is the angle between the chord line of an airfoil and the relative wind.

• It is an important factor in determining the lift and drag of an aircraft.

• It is usually measured in degrees.

• A higher angle of incidence results in more lift but also more drag.

• The angle of incidence can be adjusted by changing the position of the wing on the fuselage.

• For example, a glider has a high angle of incidence to generate

There are several types of combustion chambers used in aircraft engines.

• Can-annular combustion chamber

• Annular combustion chamber

• Can combustion chamber

• Tubular combustion chamber

• Reverse flow combustion chamber

Lift is created by the wings of an aircraft through the Bernoulli's principle and Newton's third law of motion.

• Air flows faster over the curved upper surface of the wing, creating low pressure, while the air below the wing creates high pressure, resulting in lift.

• The angle of attack of the wing also affects the amount of lift generated.

• The shape and size of the wing, as well as the speed and density of the air, also pl...read more

A toolkit is a set of tools used by aircraft technicians to perform maintenance and repairs on aircraft.

• Includes various types of wrenches, screwdrivers, pliers, and other specialized tools

• May also include diagnostic equipment such as multimeters and pressure gauges

• Organized in a toolbox or tool bag for easy access and transport

A lift is a platform or compartment raised and lowered in a vertical shaft to transport people or goods between floors.

• Lifts are commonly used in buildings with multiple floors to provide easy access for people and goods.

• They are powered by electric motors and controlled by buttons or switches inside the lift.

• Lifts can be hydraulic, traction, or pneumatic depending on the mechanism used to move the platform.

• Safety feat...read more

Bernoulli's theorem states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy.

• States that the total mechanical energy of a fluid remains constant along a streamline

• Used to explain the behavior of fluids in motion, such as in pipes or over wings of an airplane

• Mathematically expressed as P + 1/2ρv^2 + ρgh = constant, where P is pressure
