When fault indications are shown, how should they be prioritized on the Longitude 700?

• A. Ignore faults below a threshold
• B. Reboot the EICAS and continue
• C. Notify passengers of fault
• D. Prioritize safety-critical systems and follow QRH for abnormal indications

Answer: (D)

When fault indications appear, the priority is to protect safe flight by focusing on systems that are critical to flying the airplane. On the Longitude 700, you handle fault indications by addressing safety-critical systems first and using the QRH (Quick Reference Handbook) to determine the exact abnormal-indication procedures. The QRH provides the standardized steps for each fault scenario, helping you assess urgency, manage workload, and decide whether to continue flight, divert, or land.

Rebooting systems or continuing without following the QRH can mask underlying issues or create new problems, and ignoring faults because they seem minor can lead to degraded performance or cascading failures. Notifying passengers has no bearing on flight safety and is not part of the fault-management process.
