A320 Primary&Secondary pack controller fault- question
Dear All
In some Airbus 320 aircrafts, the FCOM states "Primary and Secondary Channel Failure
As a backup corresponding pack outlet temp is controlled by the anti-ice valve and is stabilized to a temp between 5C and 30C in a maximum of 6 minutes."
What do they mean by -- Pack outlet temperature is controlled by the anti ice valve, what does anti ice have to do with controlling pack outlet temperature.. Confused, pls help
Regards
