If RCCs are reported as 3, what is the maximum crosswind component for landing?

When Runway Condition Codes (RCCs) are reported as 3, it indicates that the runway is considered to have snow or ice, which results in a reduced friction level. Under these conditions, knowing the maximum crosswind component for landing is critical for ensuring safety and control during touchdown.

For RCC 3, the maximum crosswind component is typically well defined in the aircraft's operating manual. The operational limits take into account the decreased performance of the aircraft on slippery surfaces. Therefore, the value of 15 knots reflects these operational parameters, providing a conservative limit that maintains safety margins while allowing for some crosswind operations under compromised runway conditions.

This limit is determined through extensive testing and reflects the aircraft's capabilities while considering the potential reduction in braking effectiveness and directional control on a less-than-ideal runway surface. Adhering to this maximum crosswind component ensures pilots can land the aircraft safely even in adverse weather conditions, minimizing the risk of skidding or loss of control on landing.
