What mechanism may be used to reconcile sensor sources when misalignment is detected?

• A. Ignore mismatches and proceed
• B. Shut down the system immediately
• C. Record and wait for operator instruction
• D. Trigger an SOE to reconcile or switch sources

Answer: (D)

When sensor data from multiple sources don’t align, you need a controlled, auditable action that preserves data integrity and system safety. The mechanism used is triggering a System Operation Event (SOE) to orchestrate reconciliation or a switch of sources. An SOE provides a formal, repeatable path: it flags the discrepancy, directs the system to re-sync or select the most reliable source, and updates the relevant data paths and displays accordingly. This keeps critical calculations and functions fed by consistent data and creates a traceable record for maintenance and review.

Ignoring the mismatch risks basing decisions on inconsistent information. Shutting down right away is too disruptive if a safe reconciliation is possible. Waiting for operator instruction can introduce unnecessary delay. The SOE approach gives you timely, controlled handling of the misalignment within established procedures.
