Which reference document is followed for fire-related abnormal procedures on a narrowbody?

• A. QRH (Quick Reference Handbook)
• B. MEL (Minimum Equipment List)
• C. FCOM (Flight Crew Operating Manual)
• D. POH (Pilot's Operating Handbook)

Answer: (A)

This question tests knowing which document provides the step-by-step actions for abnormal situations like a fire in flight. The Quick Reference Handbook is the concise source used in the cockpit for in-flight abnormal procedures, including fires. It presents prioritized, system-specific checklists that guide crews through the exact actions to take, helping to manage workload and ensure a safe, coordinated response.

The MEL deals with equipment status and legality of flight with certain items inoperative, not with the procedural steps for emergencies. The FCOM contains broader operating procedures and guidance but the immediate, action-oriented checklists for emergencies come from the QRH. The POH covers normal operating procedures and limits for a specific aircraft, not the targeted abnormal procedures used in flight.

So, for fire-related abnormal procedures on a narrowbody, the QRH is the referenced document.
