Which of the following is NOT a limitation of pressure-sensitive paint?

  • A.It can only be used on supersonic models
  • B.Its response is temperature sensitive
  • C.It requires careful calibration
  • D.It needs optical access to the surface

Answer: A

The paint works across the speed range and is used routinely at subsonic and transonic conditions. Its genuine limitations are the temperature sensitivity, the calibration effort and the need to see the painted surface, all of which are real constraints on where it can be applied.
