A weight penalty function is used in optimisation to

  • A.Put weight on a common measure
  • B.Punish the design team for overruns
  • C.Reduce the aircraft's weight automatically
  • D.Set the certification basis

Answer: A

Correct answer: Put weight on a common measure

An optimiser cannot trade a kilogramme against a drag count or a fuel burn figure until all three are expressed in the same currency. The weight penalty function performs that conversion, so that a design change can be judged on a single number. It is an accounting device within the optimisation, not a management sanction and not a certification matter.
