How many portable halon fire extinguishers are aboard, and where are they located?

• A. 2 total; both in cabin
• B. 3 total; 2 in cabin and 1 on flight deck
• C. 4 total; 3 in cabin and 1 on flight deck
• D. 5 total; 4 in cabin and 1 on flight deck

Answer: (C)

Portable halon extinguishers are positioned to cover both the cabin and the cockpit, ensuring quick access in case of a fire anywhere on board. The standard setup is three extinguishers in the cabin—placed for reach from different cabin areas—and one additional extinguisher on the flight deck for the cockpit, giving a total of four. This distribution ensures crew can respond rapidly to cabin fires as well as fires that may occur in the cockpit or around avionics, without having to move through the cabin to reach an extinguisher. More or fewer extinguishers would either leave gaps in coverage or add unnecessary weight and clutter, while five would exceed typical airline practices.
