WEIGHT AND BALANCE
Reims-Cessna F172 · Weight And Balance
Overview
This document provides essential information for calculating the weight and balance of a Cessna aircraft, specifically focusing on the Cessna 172 model. It outlines the procedures for determining the aircraft's weight and center of gravity (CG) limitations, ensuring safe operation within prescribed parameters. The document includes a sample loading problem to illustrate the process, along with a loading graph and center of gravity moment envelope to assist pilots in verifying acceptable loading conditions. This information is crucial for pilots and operators to maintain safety and performance standards during flight operations.
- Use the licensed Empty Weight and Moment/1000 from the Weight and Balance Data sheet.
- Calculate the moment for each item to be carried using the Loading Graph.
- Ensure the total weight and moment fall within the Center of Gravity Moment Envelope.

Weight and Balance Calculation
The document explains how to calculate the weight and balance for a Cessna 172. It emphasizes the importance of using the licensed empty weight and moment from the Weight and Balance Data sheet, along with any changes noted on FAA forms. The process involves determining the moment for each item to be carried and ensuring the total weight and moment fall within the center of gravity moment envelope.
Sample Loading Problem
A sample loading problem is provided to demonstrate the calculation process. It lists various weights and moments for items such as oil, pilot, passengers, and fuel. The total aircraft weight is calculated, and the resulting point is checked against the center of gravity envelope to confirm that the loading is acceptable.
Center of Gravity Envelope
The document describes the center of gravity envelope, which is a graphical representation used to determine if the calculated weight and balance are within safe limits. Pilots must ensure that their loading point falls within this envelope for safe flight operations.
Safety notes
- Loading must be within prescribed weight and center of gravity limitations.

WEIGHT AND BALANCE. The following information will enable you to operate your Cessna within the prescribed weight and center of gravity limitations. To figure the weight and balance for your particular airplane, use the Sample Problem, Loading Graph, and Center of Gravity Moment Envelope as follows: Take the licensed Empty Weight and Moment/1000 from the Weight and Balance Data sheet, plus any changes noted on forms FAA-337, carried in your airplane, and write them down in the proper columns. Using the Loading Graph, determine the moment/1000 of each item to be carried. Total the weights and moments/1000 and use the Center of Gravity Moment Envelope to determine whether the point falls within the envelope, and if the loading is acceptable. 172 So,nple Airplane SAMPLE LOADING PROBLEM Weight Moment {lbs) (lb - ins. /1000) 1.
