Which action should be executed to communicate outage status to ATC and operations?

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

Answer: (C)

When a sensor outage happens, the priority is to keep weather information flowing and to clearly demonstrate that the primary source is down by switching to a redundant path. Switching to backup sensors provides an immediate, controlled failover that maintains data continuity for ATC and operations, so they still have current information and know the primary system is unavailable. Once the backup is active, you can communicate the outage status as part of the ongoing system update, but the essential first step is the seamless transition to the backup data path.

Informing ATC and operations is important, but it’s most effective after the backup sensors are in use to avoid a gap in data and to show that a proper failover is in place. Activating contingency procedures is broader and may involve multiple steps; the immediate action focused on preserving data is the switch to backup sensors. Implementing approved alt routing addresses routing changes, not sensor outages, so it doesn’t directly handle the outage status.
