Which two factors do pilots control that affect the coefficient of lift?

The correct response identifies angle of attack and camber as the two factors that pilots can control which significantly influence the coefficient of lift.

Angle of attack refers to the angle between the wing’s chord line and the oncoming airflow. By increasing the angle of attack, pilots can enhance lift generation up to a certain point called the critical angle of attack, beyond which lift can stall. This relationship is crucial because as the angle of attack increases, airflow over the wing changes, affecting the pressure distribution and, consequently, the lift produced.

Camber, on the other hand, involves the curvature of the wing. By adjusting the shape of the wing or using flaps, pilots can modify the camber, which alters the lift characteristics of the wing. Increased camber, similar to an increase in angle of attack, can help increase lift at lower speeds.

Together, these two parameters are integral to controlling the lift generated by an aircraft, allowing pilots to optimize performance during different phases of flight, such as takeoff or landing. Understanding how angle of attack and camber interplay in creating lift is essential for effective aircraft operation and maneuverability.
