How does the POH address weight distribution and balance safety?

• A. It prescribes maximum speeds only.
• B. It sets CG limits and requires proper payload distribution to stay within those limits.
• C. It dictates color choices for interiors.
• D. It specifies maintenance schedules.

Answer: (B)

Weight distribution and balance safety in the POH is addressed by setting center-of-gravity limits and requiring payload to be distributed so the airplane stays within those limits at takeoff. The POH provides a weight-and-balance section with forward and aft CG limits and a chart or data table showing how weight and moment (the CG) relate to safe loading. Before flight you must verify that the loaded weight and moment place the CG inside the permitted envelope, and you may need to adjust payload or fuel to stay within those limits. Why this matters is that the center of gravity directly affects longitudinal stability and control effectiveness. If the CG is too far forward, elevator authority is reduced, making rotation and pitch control harder and potentially increasing stall speed. If the CG is too far aft, the airplane becomes more pitch-sensitive and less stable, which can lead to difficult recovery from unusual attitudes or stalls. Keeping the load within the prescribed CG range ensures predictable handling, safe takeoff and landing performance, and stable flight throughout fuel burn and payload changes. The POH guides you to manage fuel and ballast so the CG stays inside the limits as weight changes during flight, using the published loading data and procedures. It’s about knowing where the load sits and ensuring symmetry and balance, not about appearance or maintenance schedules.
