Which procedure requires the maximum crosswind limit of 10 knots in the T-6A?

The maximum crosswind limit of 10 knots in the T-6A is specifically applicable to the procedure of landing on an icy runway. This limit is crucial because icy surfaces significantly reduce the friction between the aircraft's tires and the runway, thereby increasing the risk of losing control during landing approaches and touch-down. The reduced traction requires pilots to be extremely cautious with crosswind components, as higher crosswinds can lead to difficulties in maintaining runway alignment and control.

When landing on icy surfaces, it’s essential to keep crosswind effects to a minimum to enhance safety margins. This 10-knot limit reflects the aircraft's operational safety standards ensuring that pilots can manage the challenges presented by icy conditions effectively. The other procedures listed have different crosswind limits, reflecting standard operational tolerances for those specific conditions, focusing on maintaining control during more favorable surface conditions.
