When a radar outage is detected, which action should be taken to inform the appropriate parties?

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

Answer: (B)

When radar outage is detected, getting the right people involved immediately is essential for a safe, coordinated response. Informing ATC and operations puts the decision-makers in the loop so they can assess the impact on airspace, activate the appropriate contingency plans, and coordinate with adjacent facilities, airlines, and other stakeholders. This step creates the situational awareness needed to guide the rest of the response, such as issuing advisories, managing traffic flow, and invoking alternate surveillance or routing as the situation evolves. While switching to backup sensors or implementing approved alternate routing may be necessary, those actions depend on having the alert and coordination established first, so information reaches the right parties without delay.
