What are the four aerodynamic forces acting on an airplane in flight in equilibrium?
- When the airplane is decelerating
- Equilibrium between the four main forces
- During unaccelerated flight (correct)
- When an airplane is accelerating

What happens to the camber of the wing when the flaps are lowered?
What happens to the camber of the wing when the flaps are lowered?
- Increases (correct)
- Remains constant
- Does not change
- Decreases

Four Aerodynamic Forces
Four Aerodynamic Forces
Lift, weight, thrust, and drag. These forces are balanced during unaccelerated flight.
What is Lift?
What is Lift?
Lift is the aerodynamic force that opposes weight, supporting the airplane in flight.
Flaps and Camber
Flaps and Camber
Lowering flaps increases the wing's camber (curvature), increasing lift and drag.

Study Notes
Aerodynamic Forces in Flight
- Four aerodynamic forces act on an airplane in flight in equilibrium: lift, weight, thrust, and drag.
Wing Support in Flight
- Lift, produced by the wings, supports the airplane in flight.
Wing Camber and Flaps
- When flaps are lowered, the camber of the wing increases.
Airplane Motion
- Rolling refers to the rotation of an airplane around its longitudinal axis (left/right movement).
Turning in Flight
- An airplane turns as a result of the forces: lift, weight, thrust, and drag, which create a net force perpendicular to the flight path, causing the plane to turn.
