An unmanned aircraft with the center of gravity too far aft is most likely to exhibit which characteristic?
Why →
When CG moves aft of approved limits, longitudinal stability decreases. The aircraft pitches up, and the elevator or flight controller may lack authority to push the nose down. Extreme aft CG can result in a pitch-up that cannot be recovered. Aft out-of-limits is more dangerous than forward out-of-limits.The trap →
Aft CG does NOT increase stability. It decreases it. Forward CG creates stability with control issues. Aft CG removes stability and pitch-recovery authority, making stall recovery potentially impossible.SOURCE → PHAK Chapter 5 / Chapter 10, Weight and BalanceCHECKED APR 21ACS IV.A.K2MED
