If during a flight there is a failure in the two air conditioning packs 10HM (11HM), you can push the RAM AIR pushbutton switch 4HZ.
When you push the RAM AIR pushbutton switch:
-
the altitude of the aircraft must be less than 10000 ft. (3050 m),
-
the cabin differential pressure must be less than 70mbar (1.0 psi).
The emergency ram-air-inlet actuator 7HZ extends and the emergency ram-air inlet moves into the external airflow. Fresh air is pushed into the ram air system and flows through ducts to the mixer unit in the cabin air distribution and recirculation system.
The cabin pressure controllers 11HL (12HL) control the outflow valve 10HL to an approximately 50% open position.
You can connect a ground air cart to the LP ground connection for ventilation of the aircraft. It is not necessary to operate the air conditioning packs

这是考题吗？

飞行程序也写的是下降到10000英尺以后，且△P小于1psi
