If the runway is expected to be wet what is the minimum effective runway length required? (C054)

Explanation:
On a wet runway, braking effectiveness is reduced, so you must plan for a longer distance to land or take off. In FAA practice for Part 135, a wet-runway correction of 1.15 is applied to the dry required distance. That means the minimum effective runway length is 15% longer than the dry requirement. If the dry requirement is 5000 feet, the wet minimum becomes 5000 × 1.15 = 5750 feet. The other options either reflect no correction or larger-than-necessary increases, which don’t align with the standard 15% wet correction.
