Statement I: The stick free case sets the more restrictive aft centre of gravity limit.
Statement II: Its neutral point is the further forward of the two.
In the light of the above statements, choose the correct answer.
Answer: D
Correct answer: Both Statement I and Statement II are correct
Both are true and the second explains the first. Since a floating elevator weakens the tail's contribution, the stick free neutral point lies forward of the stick fixed one.
The aft centre of gravity limit must leave an adequate margin against whichever neutral point comes first, and that is the stick free one. Designing to the stick fixed figure would permit a loading at which the aeroplane was stable with the stick held but not with it released - which is the condition a pilot flying hands-off would actually meet.
