Which statement best captures the ballast planning approach for maintaining CG within limits on a cross-country flight?

• A. Plan ballast usage to keep CG within the envelope; lighten for landing; plan to jettison before final approach if needed.
• B. Always maximize ballast for best glide.
• C. Ignore CG considerations during planning.
• D. Jettison ballast after landing.

Answer: (A)

Ballast planning centers on keeping the aircraft’s center of gravity inside the approved range throughout the flight, even as weight and balance shift with fuel burn and payload changes. On a cross-country leg, you anticipate how the CG will move as fuel is burned and as passengers, baggage, or ballast are distributed, and you plan ballast to offset those changes so the airplane stays controllable and within limits at every phase of flight. Lightening for landing is specifically about ensuring the airplane remains within safe weight and balance during the approach and touchdown, improving handling and stall characteristics when you’re closest to the ground. Having a plan to jettison ballast before final approach, if needed, helps guarantee that the CG and weight are appropriate for the approach and landing, reducing the risk of overshooting or controllability problems. The alternative of maximizing ballast for best glide ignores balance and can push the CG outside its allowed envelope, degrading stability and control. Ignoring CG considerations during planning is unsafe because it’s the key factor that governs predictable handling. Jettisoning ballast after landing doesn’t address the balance issues encountered during the approach and landing phase of flight.
