Consider the following statements about configuration selection:

1. A high wing suits a freighter needing a low cabin floor.

2. Wing-mounted engines provide bending relief.

3. Configuration choices are easily reversed during detail design.

Which of the statements given above is or are correct?

  • A.2 and 3 only
  • B.1, 2 and 3
  • C.1 and 2 only
  • D.1 and 3 only

Answer: C

The first two are correct. The third is emphatically false: configuration choices propagate into structure, systems and tooling, and reversing one after detail design has begun is among the most expensive changes a programme can make.
