Are CG limits intended to maintain safe handling across the entire flight envelope?

• A. CG limits apply only during takeoff.
• B. CG limits apply to in-flight fuel management only.
• C. CG limits are intended to maintain safe handling, stall margins, and structural integrity across the entire envelope.
• D. CG limits apply only to landing.

Answer: (C)

Center of gravity limits are set to keep the airplane controllable, stable, and within structural limits across the whole flight envelope. They define forward and aft CG positions so that in every phase—from takeoff through climb, cruise, descent, and landing—the aircraft retains adequate elevator authority, predictable stall characteristics, and loads within design limits. If the CG shifts outside these bounds, you can lose sufficient control to recover from a stall, see reduced stability and more abrupt handling, or stress the structure during maneuvers or gusts. Fuel burn and payload changes continually move CG, so the limits must cover all plausible configurations to maintain safe handling throughout the flight. That’s why the correct choice points to safe handling, stall margins, and structural integrity across the entire envelope.
