Questions and Answers

What is the primary function of flaps on an aircraft's wings?

  • To decrease drag during cruising
  • To increase the aircraft's speed during landing
  • To reduce lift during flight
  • To enhance lift, control, and maneuverability during different phases of flight (correct)

Who made the first flight in Kitty Hawk in 1903?

  • The Wright Brothers (correct)

What is the main advantage of plain flaps on small aircraft?

  • They offer a straightforward and effective means of increasing lift during takeoff and reducing landing speeds (correct)
  • They are commonly used on large commercial aircraft
  • They are a type of flap that is separate from the main wing surface
