Which statement about the design point is FALSE?

  • A.It must lie where two constraint lines cross
  • B.It lies inside the feasible region
  • C.It is usually near a corner of that region
  • D.It is dimensionalised using the design weight

Answer: A

Correct answer: It must lie where two constraint lines cross

This is the false statement. The design point is usually placed at such an intersection, because that corner gives the lowest thrust and highest wing loading, but nothing requires it. A designer may retreat inside the region to keep margin for weight growth, or move along a boundary to match an available engine rating.

The other three are true: it must lie inside the feasible region, it is usually near a corner of it, and it is dimensionalised using the design weight to give the wing area and installed thrust.
