Which system is activated during ejection to provide oxygen?

The Emergency Oxygen System is specifically designed to provide immediate supplemental oxygen to the crew during an ejection from the aircraft. During an ejection, the rapid decompression associated with such an event can lead to a loss of cabin pressure, which poses a risk of hypoxia due to the sudden drop in oxygen availability. To counteract this hazard, the Emergency Oxygen System automatically activates, ensuring that the pilot has access to oxygen as they exit the aircraft and descend under the parachute.

The primary function of this system is to deliver a reliable source of oxygen in critical situations. While other oxygen systems may be present in the aircraft for normal operation or as backups, they are not activated automatically in the same manner as the Emergency Oxygen System when an ejection occurs. Therefore, this system is specifically tailored for emergencies, highlighting its vital role in maintaining pilot safety during such critical scenarios.
