At what angle of attack does the stick shaker activate in the T-6?

The stick shaker in the T-6 is designed to provide an early warning to the pilot that the aircraft is approaching a stall condition. The correct angle of attack at which the stick shaker activates is in the range of 15-16 units. This activation point is critical for safety, allowing pilots to recognize that they're nearing a stall before it occurs, thus giving them the opportunity to take corrective action.

While other options might reference angles or conditions related to stall, they do not accurately reflect the specific parameters set for the T-6 regarding the stick shaker's operation. For instance, stating that the activation occurs at a specific angle beyond a general range is misleading as the stick shaker is purposefully calibrated for a specific range that communicates effective pre-stall warning. Understanding these nuances helps pilots maintain control and awareness during critical flight phases.
