What is the primary source of oxygen for the crew system?

• A. One 25-liter liquid oxygen converter.
• B. One 75-liter liquid oxygen converter.
• C. Two 25-liter liquid oxygen converters.
• D. Two 75-liter liquid oxygen converters.

Answer: (A)

The primary source of oxygen for the crew system in the C-17 is one 25-liter liquid oxygen converter. This system is designed to store and convert liquid oxygen into a breathable gas for the crew during flight, especially at higher altitudes where ambient oxygen levels are insufficient for safe breathing. The design and capacity of the 25-liter converter are optimized for the needs of the crew, providing a reliable and lightweight source of oxygen that is appropriate for the aircraft's mission profile and operational requirements. The aircraft's oxygen system ensures that crew members have access to safe and adequate oxygen levels throughout the flight, particularly during extended operations or high-altitude missions where supplemental oxygen is essential for maintaining pilot and crew performance and safety.
