Which step is used to guide traffic along approved alternate routes during the outage?

• A. Activate contingency procedures
• B. Inform ATC and operations
• C. Switch to backup sensors
• D. Implement approved alt routing

Answer: (A)

When a system outage occurs, you rely on predefined responses that cover incident handling, safety, and traffic flow. Activating contingency procedures triggers the entire outage response, including using published alternate routes and coordinating with ATC and operations. This step sets the plan in motion so traffic is guided along approved alt routing and managed safely and efficiently.

Informing ATC and operations is essential, but it’s part of executing the contingency plan rather than the initiating action. Switching to backup sensors handles data inputs, not traffic routing. Implementing approved alternate routing happens as part of the contingency actions, but it is activated only after the contingency procedures are in motion.
