What is the capacity of the largest oxygen bottle in the nose compartment?

• A. 115 ft³
• B. 77 ft³
• C. 100 ft³
• D. 90 ft³

Answer: (A)

The idea is that emergency oxygen systems are sized to provide crew with a sufficient supply during a depressurization. The nose compartment houses the largest bottle, chosen to maximize available oxygen without changing other system layouts. Oxygen bottle capacity is given in cubic feet, and for this configuration the largest bottle in the nose is 115 cubic feet. The other values (77, 100, 90 cubic feet) represent smaller bottles used elsewhere or in different setups, but they aren’t the biggest in the nose compartment. So 115 ft³ is the correct capacity for the largest nose-compartment bottle.
