When is it acceptable to perform aerobatic maneuvers in the T-6?

Aerobatic maneuvers in the T-6 are permissible only with a fuel imbalance of less than 50 pounds. This limitation is crucial for maintaining the aircraft's stability and performance during such maneuvers, as a greater imbalance could adversely affect handling characteristics, particularly during dynamic maneuvers where precise control is essential.

It's important to understand that maintaining an appropriate fuel load and distribution is vital for safe operations in aerobatic situations. This ensures that the aircraft behaves predictably and within established performance parameters. The other options, such as having full fuel, engaging in aerobatics only at high altitude, or performing these maneuvers under any conditions, do not account for the critical need to manage fuel imbalance, which can lead to handling issues if not monitored closely. Therefore, adhering to the guideline of a maximum fuel imbalance of less than 50 pounds is key to ensuring safe aerobatic operations in the T-6.
