Which runway condition code triggers FO restrictions?

• A. 3 or less
• B. 2 or less
• C. 4 or less
• D. 1 or less

Answer: (B)

Runway Condition Code is a measure of braking action on a runway, with lower numbers meaning poorer braking. Airlines set operational limits tied to that code to keep operations safe when conditions are degraded. In this policy, the First Officer restrictions are activated when the Runway Condition Code is 2 or less. That threshold reflects a level of braking action where the risk during takeoff and landing increases enough that it’s prudent to limit the FO’s responsibilities and rely more on the Captain for critical tasks and decision-making.

So, when the runway is assessed as having RCC 2 or lower, the procedure calls for those FO restrictions to kick in. The other options describe thresholds that don’t align with this policy: 3 or less would be a looser limit, 4 or less even more permissive, and 1 or less would be stricter than the standard trigger.
