What is the definition of lift?
✔✔ Lift is the upward force generated by the wings of an aircraft as air flows over them,
allowing the plane to rise.
What is drag in aerodynamics?
✔✔ Drag is the resistance an aircraft experiences as it moves through the air, opposing forward
motion.
What is thrust?
✔✔ Thrust is the forward force produced by an aircraft's engine that propels the airplane through
the air.
Explain what weight means in terms of flight.
✔✔ Weight is the force of gravity pulling the aircraft toward the Earth, counteracting lift.

,What is the angle of attack?
✔✔ The angle of attack is the angle between the wing's chord line and the relative airflow.
What happens when the angle of attack exceeds the critical angle?
✔✔ When the angle of attack exceeds the critical angle, the aircraft stalls, causing a loss of lift.
What is a stall?
✔✔ A stall occurs when the airflow over the wings is disrupted, leading to a rapid decrease in
lift.
What is induced drag?
✔✔ Induced drag is the drag created as a byproduct of lift, typically increasing with the angle of
attack.
What is parasitic drag?
✔✔ Parasitic drag is the resistance caused by the aircraft's shape, surface roughness, and external
components as it moves through the air.
2
, What factors affect lift generation?
✔✔ Lift is affected by airspeed, air density, the shape of the wings, and the angle of attack.
What is the purpose of flaps on an airplane?
✔✔ Flaps are used to increase lift and drag during takeoff and landing, allowing the aircraft to
fly at slower speeds.
What is the effect of ground effect on an aircraft?
✔✔ Ground effect reduces drag and increases lift when an aircraft is close to the ground during
takeoff or landing.
How does altitude affect air density?
✔✔ As altitude increases, air density decreases, reducing lift and engine performance.
What is the difference between true airspeed and indicated airspeed?
✔✔ True airspeed is the aircraft's actual speed through the air, while indicated airspeed is the
speed shown on the airspeed indicator, adjusted for atmospheric conditions.
