Why might a pilot with a history of spontaneous pneumothorax be disqualified from flying?

• A. Recurrence risk and potential in-flight deterioration requiring emergency decompress.
• B. It does not affect flight status
• C. It improves flight performance
• D. It is always a temporary limitation.

Answer: (A)

This item tests how a history of a spontaneous pneumothorax creates a real safety risk in flight. Spontaneous pneumothorax means air has collected in the pleural space and can cause the lung to collapse. When a pilot is flying, cabin pressure is lower than at sea level, and as altitude increases, any free air in the chest can expand. That expansion raises the danger of the lung collapsing further or progressing to a tension pneumothorax, a life‑threatening emergency that would be extremely difficult to manage mid‑flight. If a recurrence occurs or if there are any unresolved air leaks, deterioration can happen quickly and may require emergency decompression. In the constrained environment of flight, with limited medical resources and the inability to perform definitive treatment, this constitutes a significant safety concern. Because of the strong risk of sudden in‑flight deterioration and the potential need for urgent intervention, pilots with this history are not cleared to fly without meeting strict medical evaluation and waiting periods, making the recurrence risk and potential in‑flight emergency the decisive factors. Other choices imply no impact or an improvement, or that the limitation is always temporary, but those don’t fit the real danger: the combination of recurrence risk and possible rapid deterioration in the flight environment.
