Where are the portable halon extinguishers located?

• A. All in the cabin
• B. Only on the flight deck
• C. Three in the cabin and one on the flight deck
• D. Three on the flight deck and one in the cabin

Answer: (C)

Fires on an aircraft can occur in both the passenger area and the cockpit, so the extinguishers must be placed where they can be reached quickly by the people who will use them. The standard setup puts three portable halon extinguishers in the cabin to handle passenger-area fires, with one extinguisher on the flight deck to address cockpit or nearby equipment fires and to give the crew immediate access from the cockpit. This arrangement ensures coverage in both key areas and avoids leaving either space without a readily available extinguisher. Having all extinguishers in the cabin would leave the flight deck without quick access, while concentrating them on the flight deck would leave cabin fires harder to reach.
