CESSNA 172C — Pilot's Operating Handbook

This document is an Advisory Circular (AC 120-27F) issued by the FAA, providing guidance on developing and approving a Weight and Balance (W&B) control program for various aircraft operations. It is particularly relevant for operators under Title 14 of the Code of Federal Regulations (CFR) parts 91, 121, 125, and 135. The AC outlines methods for establishing aircraft weight, maintaining loading schedules, and ensuring compliance with weight and balance limitations. It is intended for operators who need to manage W&B effectively, ensuring safety and regulatory compliance. The document emphasizes the importance of accurate weight calculations and provides recommendations for using average weights and maintaining records for aircraft weight and center of gravity (CG).

• Operators must establish and maintain accurate records of Basic Empty Weight (BEW) and Center of Gravity (CG).
• Aircraft should be weighed at least every 36 months, or sooner if significant modifications occur.
• Weight changes of 1 lb or greater for small cabin aircraft must be recorded in the W&B change record.
• Operators can use standard average weights for passenger calculations only if they meet specific criteria.
• Loading envelopes must account for all relevant W&B limitations and in-flight movements.
