Which resource governs the crew's actions during a volcanic ash encounter?

• A. Volcanic Ash Encounter QRH
• B. Emergency in-flight manual
• C. ATC guidelines
• D. ICAO Volcanic Rulebook

Answer: (A)

In a volcanic ash encounter, pilots rely on the Volcanic Ash Encounter QRH because it contains the exact, event-specific procedures the crew must follow. This QRH provides a concise, in-flight checklist tailored to ash scenarios, outlining the required actions for engine behavior, systems management, and decision-making steps in a clear sequence. It’s designed for rapid reference and to standardize responses across crews, ensuring the correct actions are taken promptly and consistently. The emergency in-flight manual is broader and covers emergencies in general, but it doesn’t offer the precise, ash-specific checklist needed in the cockpit. ATC guidelines govern air traffic control actions and routing, not the aircraft’s procedural steps during an ash encounter. The ICAO Volcanic Rulebook sets international policy and standards, but it isn’t the on-board, step-by-step guide used in flight.
