An aircraft's wing span comes out at 37.4 m against a 36 m gate limit. Which response gives up the least performance?

  • A.A folding wingtip
  • B.Reducing the aspect ratio
  • C.Reducing the wing area
  • D.Increasing the sweep angle

Answer: A

Folding retains the aerodynamic span in flight while meeting the parked limit. Reducing aspect ratio or area gives up induced drag or lift capability permanently, and more sweep would cost low-speed performance for no span benefit.
