Final answer:
During ejection of emergency egress from the aircraft, disconnection from the CRU-60P connector takes place at the quick-disconnect (QD) fitting.
Step-by-step explanation:
During ejection of emergency egress from the aircraft, the disconnection from the aircraft oxygen supply hose connector takes place on the CRU-60P connector at the quick-disconnect (QD) fitting. The CRU-60P connector is a high-pressure connector that allows for the rapid disconnection of the oxygen supply hose in case of an emergency.
When the ejection sequence is initiated, the ejection seat activates the pyrotechnic devices that disconnect the oxygen supply hose from the aircraft's oxygen system. This disconnection occurs at the QD fitting located on the CRU-60P connector.
The CRU-60P connector is specifically designed for use in aircraft ejection systems to ensure a secure and reliable connection to the aircraft's oxygen supply and a quick disconnection during emergency situations.
