The ByPass Valve is to modulate the pack discharge temperature by adding hot air.

The pack Flow Control Valve is electrically controlled to close for:
- Same side engine start,
- Opposite side engine start provided the crossbleed valve is open,
- Engine fire pushbutton released out,
- Ditching pushbutton set to ON.
and pneumatically controlled to close for:
- pack overheat,
- lack of air pressure.

混合活门一般状态下是关闭的，只有在Pack 1 OFF 时来确保驾驶舱有足够的空气量。
