Aerobatic maneuvers are prohibited with a fuel imbalance exceeding how many pounds?

Aerobatic maneuvers are restricted when there is a fuel imbalance exceeding 50 pounds to ensure the safety and performance integrity of the aircraft. A fuel imbalance can significantly affect the center of gravity and, consequently, the aircraft's handling characteristics during dynamic maneuvers. If the imbalance exceeds this threshold, it can lead to unexpected aircraft behavior during aerobatics, which may result in difficulties in controlling the aircraft.

Maintaining a fuel imbalance within this limit allows for more stable flight dynamics and reduces the risk of adverse effects on the aircraft's aerodynamic performance. This precaution is critical because aerobatic maneuvers involve high angles of attack and lateral loads that can exacerbate any existing imbalances. Thus, adhering to this limit is essential for conducting aerobatic maneuvers safely and effectively.
