Runway Condition Codes (RCC) are issued when more than 25% of the runway is contaminated.

• A. False
• B. Only during night operations
• C. Only when pilots request
• D. True

Answer: (D)

RCCs describe how much of the runway surface is contaminated and what braking action to expect. When more than a quarter of the runway is covered in snow, ice, slush, or standing water, an RCC is issued so pilots have a clear, standardized indication of braking performance for planning takeoff and landing. This threshold is chosen because contamination at or above that level typically has a noticeable impact on braking, enough to warrant formal communication and potential adjustments to performance data. It isn’t limited to night operations or to situations where pilots request it; RCCs are a standard part of surface-condition reporting and are issued based on the actual condition of the runway.
