A canard foreplane stalls at 14 degrees while the main wing stalls at 18. The margin protecting the wing is

  • A.14 degrees
  • B.4 degrees
  • C.32 degrees
  • D.0.78 degrees

Answer: B

The difference of 4 degrees is what guarantees the foreplane reaches its limit first. Its stall then drops the nose automatically, giving the configuration an inherent protection against reaching the main wing's stall at all.
