If a runway has more than 1/8 inch of water depth, how would braking action likely be reported?

• A. Good to Excellent
• B. Medium to Poor
• C. Nil to Poor
• D. Good

Answer: (B)

When a runway has more than 1/8 inch of water depth, it significantly impacts the braking action experienced by aircraft. This depth of water creates a risk of hydroplaning, which reduces the friction available between the aircraft's tires and the runway surface. As a result, pilots can expect that the braking effectiveness will be compromised. In this context, the appropriate reporting of braking action for such conditions would be categorized as "Medium to Poor." This classification indicates that while there might still be some braking capability, it may not be sufficient for optimal operational safety. Pilots must be aware of this diminished braking action to adjust their landing and takeoff techniques accordingly. Understanding this grading system helps pilots make informed decisions about the safety of runway conditions and manage their approach and operations in a way that mitigates risks associated with reduced braking efficiency.
