What determines the direction of roll if an accelerated stall occurs during a steep turn?

The direction of roll during an accelerated stall in a steep turn is primarily determined by whether the airplane is slipping, skidding, or coordinated. In a coordinated turn, the lift vector is properly aligned with the drag vector, allowing for smooth and balanced flight. However, if the airplane becomes uncoordinated—such as when it is either skidding (the tail moves out away from the turn) or slipping (the nose moves towards the turn)—it can lead to an increase in the risk of a stall.

When a stall occurs under these conditions, the imbalance created by the differential drag will influence the roll. For instance, if the plane is skidding, the roll might tend to go in the direction opposite to the turn, while a slip could cause the aircraft to roll in the direction of the turn. Therefore, understanding the state of coordination within the turn is critical for predicting the direction of roll during an accelerated stall. This also highlights the importance of maintaining proper coordination and controlling the aircraft's flight path effectively during steep turns to avert uncoordinated conditions that could lead to stalls.
