Which of the following is NOT a requirement for SWOA airport limitations?

The correct choice identifies a condition that does not align with the typical limitations for SWOA (Standard Weather and Operational Approach) airport operations. Specifically, the allowance for a tailwind greater than 3 knots is not a typical requirement for SWOA procedures, as these usually aim to ensure safe landing conditions.

In aviation, tailwinds can complicate landing operations by reducing the aircraft's control during landing and increasing the landing distance required. Therefore, having a tailwind exceeding a certain limit, like 3 knots, contradicts the safety measures typically associated with operational limitations.

In contrast, full vertical guidance, operable thrust reversers, and the recency of braking action reports are all important safety measures that help ensure optimal landing conditions. Full vertical guidance assists pilots in making precise approaches, operable thrust reversers are crucial for effective deceleration upon landing, and timely braking action reports inform pilots of current runway conditions.
