NTSB Wet Runway Safety Spotlight Addresses Excursion Risks

Aviation safety officials are reviewing a new NTSB wet runway safety spotlight issued by the National Transportation Safety Board. The document highlights recurrent risks of runway excursions and emphasizes the importance of accurate braking action reports during wet conditions. Pilots and dispatchers are encouraged to scrutinize performance calculations ahead of the summer storm season.

Performance Calculations Under Scrutiny

The NTSB recommendations focus on wet runway landing safety, noting that wheel-braking friction calculations can be substantially less than FAA runway-condition figures used for planning. According to industry reports, current assumptions may be overly optimistic, leaving crews with less stopping margin than expected. This discrepancy drives the need for updated braking action reports protocols to better reflect real-world friction values during heavy rainfall.

Operational Guidance for Pilots

Safety managers are utilizing this alert to update standard operating procedures regarding runway excursion prevention. The spotlight aligns with broader industry guidance from Airbus and NBAA, which emphasize that wet runways differ significantly from contaminated surfaces in terms of depth and friction. The NTSB continues to monitor these conditions to ensure the FAA updates how runway conditions are evaluated. As summer convective weather approaches, operators are advised to re-examine alternate planning and landing-distance calculations to maintain safe margins.
