Which type of maneuvers are included in the prohibited spin category?

Aerobatic spins are included in the prohibited spin category because they pose significant risks to the aircraft and pilots, as they can lead to uncontrolled flight conditions. These spins typically occur during aerobatic maneuvers which involve high angles of attack and aggressive control inputs, increasing the potential for entering an unrecoverable spin situation. The T-6 aircraft has specific operational limits designed to ensure safety and prevent scenarios where recovery becomes difficult or impossible. Such limitations are particularly relevant in training environments to emphasize safe piloting practices and adherence to established operating guidelines.

The other options may involve various forms of aircraft maneuvering, but aerobatic spins directly relate to the category of spins that are typically restricted due to their inherent danger and complexity, highlighting the importance of maintaining control during flight operations.
