Which statement about dihedral is TRUE?

  • A.It reduces induced drag
  • B.It raises the critical Mach number
  • C.It generates a restoring rolling moment in sideslip
  • D.It increases the wing's lift in level flight

Answer: C

In a sideslip the lower wing meets the flow at a greater effective incidence and lifts more, rolling the aircraft back towards level. Sweep and a high wing position both add to the same effect, so the three are traded together.
