What should you do if an annunciator indicates an out-of-limit condition in flight?

• A. Continue the flight and monitor conditions
• B. Follow the published abnormal procedures per QRH/AFM.
• C. Acknowledge and reset the annunciator, then continue
• D. Divert immediately

Answer: (B)

When an annunciator shows an out-of-limit condition, the proper course is to follow the abnormal procedures published in the QRH and AFM. Those checklists are written to guide you through verifying the fault, isolating the affected system, and taking actions to bring parameters back within safe limits or to determine the safest next step. This structured response helps ensure a consistent, safe handling of the fault and supports clear crew coordination. Continuing the flight and just monitoring won’t address the abnormal condition, and resetting an annunciator can mask the fault and remove important safety indicators. Diverting immediately isn’t inherently required unless the QRH/AFM directs diversion for that specific condition. The correct approach is to execute the prescribed abnormal procedures, assess the outcome, and decide on the appropriate next action, which could include a diversion if warranted by the procedure.
