Lift Production and Primary Flight Controls Quiz

Which principle explains how a wing generates lift due to pressure differences?

• Newton’s First Law

• Bernoulli’s Principle

• Coandă Effect

• Boyle’s Law

Newton’s Third Law states that for every action, there is an equal and opposite reaction. How does this apply to lift?

• The airflow over the wing slows down, increasing pressure.

• The wing pushes air down, and the air pushes the wing up.

• The air separates from the wing, reducing drag.

• The wing creates turbulence to generate lift.

The Coandă Effect helps in lift production because:

• It increases drag to slow the aircraft down.

• Airflow follows the curved shape of the wing, keeping it attached.

• It prevents air from flowing over the wing.

• It only applies to helicopters, not fixed-wing aircraft.

What is the name of the front part of an aerofoil that first meets the airflow?

• Trailing edge

• Leading edge

• Camber

• Chord line

What is the name of the rear part of an aerofoil where the airflow from above and below meets?

• Leading edge

• Trailing edge

• Chord line

• Camber

What is the imaginary straight line connecting the leading edge and trailing edge of an aerofoil?

• Lift line

• Angle of attack

• Chord line

• Camber

What term describes the curved shape of an aerofoil?

• Angle of attack

• Camber

• Chord line

• Trailing edge

What is the angle between the chord line and the relative airflow?

• Angle of incidence

• Angle of attack

• Camber

• Lift angle

Increasing the angle of attack up to a certain point will:

• Decrease lift and increase drag

• Increase lift and decrease drag

• Increase lift, but too much can cause a stall

• Have no effect on flight

Which of the following factors affects lift production?

• Camber, angle of attack, airspeed

• Wing color, air pressure, engine size

• Chord line, leading edge, trailing edge

• Flap position, landing gear position, tail size
