Theory of Flight

Question 1

Chord Line

Answer 1

An imaginary line on the wing that connects the leading edge to the trailing edge.

Question 2

Mean Camber Line

Answer 2

Cuts the wing into two equal parts.

Question 3

What is the Lift Equation?

Answer 3

½C (rho) v²A

C = Coefficient of lift (controlled by AoA or flaps)

(rho) = Density of Air

v = Speed of airflow over wing

A = area of wing.

Question 4

Camber

Answer 4

Distance between Mean Camber Line and Chord Line.

Greater camber = greater lift.

Question 5

Angle of Attack

Answer 5

Angle between the airflow and the wing.

Question 6

Angle of Incidence

Answer 6

Angle between the longitudinal axis of the plane and the chord line.

Question 7

What’s the usual “critical angle of attack”

Answer 7

16deg
