During a radar outage at a facility equipped with weather sensors, which action directly addresses rerouting air traffic?

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

Answer: (A)

When radar is out, the priority is to keep air traffic flowing safely by directing flights along routes that are pre-approved for use during outages. Implementing approved alt routing means ATC issues clearances that guide each aircraft along alternative paths designed to maintain separation and orderly flow while the primary surveillance or guidance is unavailable. This directly changes the aircrafts’ trajectories to avoid the affected area and preserves safety and efficiency.

Other options, while important, don’t accomplish the routing change by themselves. Activating contingency procedures sets the overall response and triggers necessary steps, but it doesn’t automatically redirect traffic. Informing ATC and operations ensures everyone is on the same page, but communication alone doesn’t physically reroute aircraft. Switching to backup sensors helps restore surveillance capabilities, which is valuable, but it doesn’t directly address how aircraft are routed around the outage.
