Chapter 3 A Four forces Lift Ground effect

Front

What effect do changes in the center of pressure of a wing have on an aircraft?

Back

Changes in the center of pressure affect the aircraft’s aerodynamic balance and controllability.

Front

How is the angle of attack defined?

Back

The angle of attack is defined as the angle between the chord line of the wing and the relative wind.

Front

What is one purpose of wing flaps?

Back

One purpose of wing flaps is to enable the pilot to make steeper approaches to a landing without increasing the airspeed.

Front

What is ground effect in aviation?

Back

Ground effect is the result of the interference of the surface of the Earth with the airflow patterns about an airplane.

Front

Does the angle of attack at which an airplane wing stalls change with gross weight?

Back

No, the angle of attack at which an airplane wing stalls remains the same regardless of gross weight.

Front

What is the significance of the center of pressure in aircraft design?

Back

The center of pressure is significant because it influences the stability and control of the aircraft during flight.

Front

What happens to lift as the angle of attack increases?

Back

As the angle of attack increases, lift generally increases up to a certain point before stalling occurs.

Front

What is the relationship between lift and airspeed?

Back

Lift is directly related to airspeed; as airspeed increases, lift increases, assuming all other factors remain constant.

Front

How do wing flaps affect lift and drag?

Back

Wing flaps increase lift and drag, allowing for lower speeds during takeoff and landing.

Front

What is the stall angle of attack?

Back

The stall angle of attack is the angle at which the wing can no longer produce sufficient lift, leading to a stall.
