Which braking action code corresponds to a braking action rating of "Good" (≥0.40)?

The braking action code that corresponds to a braking action rating of "Good," which is noted as being greater than or equal to 0.40, is Code 5. In the context of air law and aviation operations, different braking action codes are established to communicate the braking performance of runways to pilots.

A rating of "Good" typically indicates that the runway surface provides a satisfactory level of friction for aircraft during landing and takeoff, allowing for safe deceleration and control. This rating is essential for flight safety, as it informs pilots about the conditions they can expect upon landing, influencing their approach and landing techniques.

Braking action codes provide a universally understood language to communicate runway conditions, helping to prevent accidents associated with poor braking performance. Codes are generally scaled, with lower numbers indicating poorer braking conditions and higher numbers indicating better conditions. Code 5, representing "Good," signifies that pilots can expect reliable braking performance.
