What fuel amount should be maintained before embarking on aerobatics?

To ensure safety during aerobatic maneuvers in the T-6A, a minimum fuel amount is established to account for varying maneuvers and any potential fuel slosh that may occur during activity. Maintaining 150 pounds of fuel is necessary to provide a safety margin and ensure the aircraft remains within its operational limits, particularly during aerobatic flight where dramatic changes in orientation can impact fuel distribution.

This amount allows for enough reserve fuel in case of unexpected circumstances, such as an extended maneuver or changes in flight direction that may lead to fuel starvation. The other options, while they may provide greater safety margins, are not the minimum required to ensure safe operations during aerobatics. Thus, 150 pounds is the specified minimum that must be adhered to prior to engaging in aerobatic flight in the T-6A.
