Where must a record be kept of the current empty weight and the current center of gravity of an aircraft?

• A. In the aircraft flight manual.
• B. In the aircraft flight manual or weight and balance records required by 14 CFR § 23.1583.
• C. In the maintenance logbook only.
• D. In the ground handling manual.

Answer: (B)

Maintaining the current empty weight and center of gravity where it’s readily available for flight planning and regulatory review is essential. The official source can be the aircraft’s flight manual or the weight and balance records required by 14 CFR 23.1583. This arrangement ensures the data is up to date after any modifications or loading changes and is accessible to the crew when planning a flight or during inspections. Keeping this information only in the maintenance logbook doesn’t meet the requirement, since that log is for maintenance history, not loading data. A ground handling manual is not related to weight and balance documentation. If the flight manual already contains the weight and balance data, that satisfies the rule as well.
