Which braking action code represents a "Medium" condition (0.30-0.35)?

The "Medium" braking action code, which represents a coefficient of friction between 0.30 and 0.35, is designated as Code 3. This coding system is used in aviation to communicate the conditions of runway surfaces to pilots and ground crews, essentially providing a scale to understand how well an aircraft can stop.

In this specific case, Code 3 indicates that the braking conditions are fair but could still pose some limitations for aircraft operations, implying that pilots should take extra care when landing or taking off under such conditions. It is important for pilots to interpret these codes accurately to ensure safety during operations, as each code provides a different level of indication regarding runway surface conditions.

Understanding these codes is critical for flight safety and helps in making informed decisions regarding aircraft operations, especially during inclement weather or adverse surface conditions.
