Few 320 system questions.
Just looking for clarification, what are the differences between the TWO "RAT MAN ON" - on the hyd overhead panel section, and then "MAN ON" on the emerg elec power section.
Also, the ram air inlet is basically closed in flight, and will be opened automatically if needed to?
It has to be closed on ground if there is heavy rain by pushing override on the extract Push Button, is this correct?
Also when enroute and smoke in encountered both blower and extract have to be set to override I believe.
What exactly does this do?
