Which of the four forces of flight acts opposite to the direction of motion?
Answer: Drag
Drag is the aerodynamic force that opposes an aircraft's forward motion through the air.
What is the term for the angle between the chord line of a wing and the relative wind?
Answer: Angle of attack
The angle of attack is the angle between the wing's chord line and the relative wind, directly affecting lift production.
At what angle of attack does a wing typically stall?
Answer: 18–22 degrees
Most wings stall at approximately 18–22 degrees angle of attack when airflow over the upper surface separates.
According to Bernoulli's principle, what happens to air pressure as velocity increases?
Answer: Pressure decreases
Bernoulli's principle states that as the velocity of a fluid increases, its pressure decreases, which helps generate lift over a wing.
What type of drag is caused by the production of lift?
Answer: Induced drag
Induced drag is a byproduct of lift generation, caused by wingtip vortices that redirect airflow and produce rearward force.
Which wing design feature reduces induced drag by limiting wingtip vortices?
Answer: Winglets
Winglets are vertical extensions at wingtips that reduce the strength of wingtip vortices, thereby decreasing induced drag.
