Why is an excessively aft center of gravity considered especially hazardous?
Choices
It makes the airplane too stable to maneuver
An aft CG reduces stability rather than increasing it.
✓ It reduces stability and can make stall or spin recovery difficultcorrect
An aft CG lowers stability so the airplane may not recover from a stall or spin.
It sharply increases the stall speed
An aft CG lowers stall speed; a forward CG raises it.
It always exceeds the maximum gross weight
CG position is independent of gross weight.
Why
An aft CG reduces longitudinal stability. Beyond the aft limit the airplane may be unable to recover from a stall or spin, which is why the aft limit is safety-critical.
