Which action is most consistent with activating contingency procedures during a radar outage?

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

Answer: (A)

Activating contingency procedures is the initiating action in a radar outage response. It starts the preplanned, standardized sequence that keeps air traffic safe when radar data isn’t available. By turning on the contingency plan, everyone shifts to non-radar control methods, establishes the required communication channels, and sets the framework for the rest of the response. Once the plan is activated, actions like informing ATC and operations, implementing approved alternate routing, and switching to backup sensors are carried out as part of executing the contingency procedures. But the essential first step is to activate the plan itself, because it coordinates and unlocks the subsequent safety-focused actions.
