Which term refers to the weight added to an aircraft to keep it in proper weight and balance?

• A. Block Time
• B. CABIN
• C. APU
• D. Ballast

Answer: (D)

In weight and balance, ballast is the term for adding weight to adjust the aircraft’s center of gravity so it sits within safe limits. This extra weight is used to fine-tune balance when passenger and cargo placement or fuel burn would otherwise push the CG outside the allowable range. Ballast can be weights or fluid added in designated locations to shift the balance as needed. The other terms describe different concepts: block time is the duration of a flight, cabin refers to the interior area, and APU is the auxiliary power unit used for electrical and pneumatic power.
