Which code indicates a "Medium to Poor" braking action?

The designation of "Medium to Poor" braking action corresponds to Code 2. In aviation safety, particularly in the context of runway conditions and pilot assessments, various codes are used to communicate the state of braking action to ensure safe takeoff and landing operations.

Code 1 indicates "Good" braking action, suggesting that the runway conditions are optimal for safe aircraft operation. Code 3 typically signifies "Poor" braking action, where caution is warranted. Code 4 indicates "Nil" braking action, meaning that the runway is extremely slippery and could pose significant hazards to aircraft operation.

Code 2 serves as an intermediary designation, providing critical information that the braking action is not at the level of good but still stronger than very poor conditions. This level of clarity helps pilots make informed decisions regarding their landing approaches and runway choices, ensuring safety in varied weather and runway conditions. Thus, Code 2 effectively communicates that caution should be taken due to medium to poor braking action, aligning with best practices in air law and safety protocols.
