What is the minimum altitude requirement for oxygen for all crew members?

• A. 12,500 feet
• B. 14,000 feet
• C. 15,000 feet
• D. 10,000 feet

Answer: (B)

The minimum altitude requirement for supplemental oxygen for all crew members is specifically set at 14,000 feet. At this altitude, hypoxia can become a serious concern as the partial pressure of oxygen in the air decreases, leading to reduced oxygen availability for pilots and crew. Federal Aviation Administration (FAA) regulations dictate that when flying above this altitude, all crew members must have supplemental oxygen available to maintain optimal cognitive and physical performance. While supplemental oxygen is recommended at lower altitudes, such as 12,500 feet for flights longer than 30 minutes, and 10,000 feet for passengers, it is the 14,000 feet threshold that mandates its use for all crew members without exception to ensure safety and prevent the onset of hypoxia. This standard helps ensure that the crew remains fully capable of operating the aircraft safely in compliance with aviation regulations.
