Arrange the steps of a first-pass horizontal tail sizing in the order they are carried out:

1. Compute the required tail area

2. Choose a tail volume coefficient from comparable aircraft

3. Check elevator authority at the forward centre of gravity limit

4. Establish the tail arm from the fuselage layout

Select the correct sequence.

  • A.4, 2, 3, 1
  • B.2, 1, 4, 3
  • C.2, 4, 1, 3
  • D.1, 2, 4, 3

Answer: C

The coefficient comes first from precedent, then the arm from the layout already fixed, then the area falls out of the definition, and only then is the resulting tail checked for control authority. Computing an area before knowing the arm is meaningless.
