What happens to the emergency oxygen system during ejection?

The emergency oxygen system is designed to support the pilot in case of ejection, ensuring that they have breathable oxygen during the critical moments immediately following ejection. When the ejection occurs, the system provides a continuous flow of oxygen for a duration of approximately 10 minutes or until the seat and pilot separate. This capability is crucial as it helps prevent hypoxia in the potentially hazardous environment at altitude where ejection may occur.

The system's design accommodates the immediate physiological needs of the pilot, ensuring they have sufficient oxygen to safely descend to a lower altitude where the atmosphere is breathable, or until they can activate their personal oxygen supply upon separation from the ejection seat. The duration of oxygen supply and the timing of activation are meticulously structured to prioritize pilot safety during these high-risk scenarios.
