Above what altitude do all occupants in a non-pressurized cabin require supplemental oxygen?

• A. 12,500 feet
• B. 14,000 feet
• C. 15,000 feet
• D. 16,000 feet

Answer: (C)

Supplemental oxygen is required for all occupants of a non-pressurized cabin when flying above 15,000 feet. According to the regulations established by the Federal Aviation Administration (FAA), at altitudes between 12,500 feet and 14,000 feet, supplemental oxygen is required for crew members if the flight is over 30 minutes, but it is not required for passengers. Once the altitude exceeds 15,000 feet, all occupants, including passengers, must have access to supplemental oxygen regardless of flight duration. This regulation is in place to ensure the safety and health of all individuals aboard the aircraft, as the human body begins to experience hypoxia— a deficiency in the amount of oxygen reaching the tissues— at these elevated altitudes. Thus, the correct understanding of when supplemental oxygen is needed is crucial for flight safety.
