Aerodynamics, Assembly, and Rigging
Chapter 2 – Questions and Answers
Already Passed
What is the primary force that opposes gravity in flight?
✔✔ Lift
How does increasing the angle of attack affect lift?
✔✔ It increases lift up to a critical point before causing a stall
What is the purpose of ailerons on an aircraft?
✔✔ To control roll by increasing or decreasing lift on the wings
Why is wing dihedral important in aircraft stability?
✔✔ It helps restore the aircraft to level flight after a disturbance
What happens when an aircraft exceeds its critical angle of attack?
✔✔ A stall occurs due to loss of lift
1
,What is the function of an aircraft's rudder?
✔✔ To control yaw movement
How does increasing airspeed affect lift?
✔✔ It increases lift by increasing airflow over the wings
Why are flaps used during takeoff and landing?
✔✔ To increase lift and allow lower speeds for safer operations
What is the primary function of an aircraft's elevator?
✔✔ To control pitch movement
Why is center of gravity (CG) important in aircraft stability?
✔✔ It affects balance, control, and overall flight performance
What aerodynamic force resists forward motion through the air?
✔✔ Drag
2
, How does wing aspect ratio affect flight performance?
✔✔ A higher aspect ratio improves efficiency and reduces drag
What happens when the center of gravity is too far forward?
✔✔ The aircraft becomes nose-heavy and harder to pitch up
Why is washout used in wing design?
✔✔ To prevent wingtip stalls by reducing the angle of attack at the tips
What is induced drag?
✔✔ Drag that results from wingtip vortices and lift production
Why is wing loading important in aircraft design?
✔✔ It affects takeoff, landing, and maneuverability
What is the purpose of trim tabs on control surfaces?
✔✔ To reduce pilot workload by maintaining a steady flight position
