At what altitude does short-term memory impairment due to hypoxia typically begin?

• A. 8,000 ft
• B. 12,000 ft
• C. 16,000 ft
• D. 22,000 ft

Answer: (B)

Short-term memory impairment due to hypoxia typically begins at around 12,000 feet. At this altitude, the partial pressure of oxygen decreases, which can lead to a deficiency of oxygen in the brain and result in cognitive impairments, including short-term memory issues. This is a critical threshold that is frequently discussed in aviation safety and human factors training because it highlights the impact of altitude on cognitive functions, which are essential for pilots to perform their duties effectively. Understanding this altitude is crucial for maintaining awareness of the risks associated with flying at higher elevations without supplemental oxygen. As altitude increases, the risk of hypoxia-related impairments progresses, making it vital for pilots to recognize these effects early.
