Which of these is NOT a purpose of a digital mock-up?

  • A.Finding clashes between systems and structure
  • B.Rehearsing maintenance access
  • C.Checking assembly sequence
  • D.Replacing all physical testing

Answer: D

Correct answer: Replacing all physical testing

A digital mock-up finds clashes between systems, structure and equipment, rehearses maintenance access with a human model and a tool envelope, and checks that the assembly sequence is physically possible - all things that were once discovered on the first article at enormous cost. What it cannot do is replace testing: material behaviour, fatigue, fastener joints, and the many effects that emerge only in real hardware still have to be measured.
