Design freeze is significant because

  • A.It ends the certification process
  • B.It gives detail design a stable basis
  • C.It means no further work is required
  • D.It marks the first flight

Answer: B

Thousands of people cannot detail-design against a moving configuration, so at some point the shape is fixed and changes become formal and expensive. Freezing too early risks locking in a poor choice; too late wastes the design workforce.
