How many oxygen bottles are in the nose cone area?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (B)

Two oxygen bottles are installed in the nose cone area to provide a reliable, ready-to-use source for the cockpit crew during depressurization while keeping the system compact and well-protected. This setup offers the necessary volume and redundancy—if one bottle or its regulator is out of service, the other still supplies oxygen so pilots can descend safely and continue to breathe until a safe altitude is reached. Placing the bottles in the nose cone minimizes weight and routing complexity and keeps the regulators and masks immediately accessible to both pilots. A single bottle would risk running out too quickly and would lack redundancy, while adding more bottles would add unnecessary weight and space without proportional safety benefits.
