aerodynamicsFAA-published sample question (AGI, Aug 2021)
What is the effect of center of gravity on the spin characteristics of a fixed-wing aircraft? If the CG is too far
A
aft, a flat spin may develop.✓ Correct Answer
B
forward, spin entry will be difficult.
C
aft, spins can become high-speed spirals.
Explanation
The Airplane Flying Handbook warns that with the CG too far aft the airplane may enter a flat spin, in which the nose stays high and recovery may be difficult or impossible because the elevator lacks authority. A forward CG makes spins more likely to become spirals and easier to recover from.
