A320 Ram Air / valve /switch / function / reason
 

Can any A320 current answer this, please . .

What does the Ram Air do when switch is selected to open Ram Air Valve

What is the Ram Air for?

[I thought it was for air inlet in the event of a pack failure, total pack failure.]

I also thought it was for fast smoke removal (in case somebody had burnt the dinner in the galley . . .etc)

Does/will having the Ram Air . . . open / letting in air, affect or do anything to the Cabin pressure significantly/critically . . ?

Thank you for your time - am not trying to put you on the spot I just cannot figure out ram air. or find it anywhere, yet.

Hi Natstrackalpha,
Allows ram air to flow through the pack inter cooler ducting into the cabin (without going through the pack).
Conditioning the cabin when de-pressurised and no pack operation.

Correct or deliberate turn off of packs.

Faster smoke removal using pack on high flow - but if smoke is coming from both packs then it is an alternative method.

Oh Yes! (Thanks Churchill) Zero delta pressure.

Rudderrat,

Thank you for your response, much appreciated?

I don`t see the significance of Churchill? If this a ***s take because I`m thick? Not all Brits are thick, am the only one in the country.

In which case (ref: paranoia above . . ) - one does assume then that the massive input of pressure from the bleeds - in order to pressurise the aicraft under normal conditions, cannot/will not be met by the Ram Air . . System.

Just taking my fluffy thick brain a walk through potential knowledge: . .

One can assume then that with all pressurisation normal - opening the ram air for absolutely no reason would cause a depressurisation ,despite the fact that air is entering the ram air sys at 420kts . . ?

ok, thanks. Have a great day!

Hi Natstrackalpha,
Since you live not far from the edge of the Milky Way Galaxy in the Orion Arm, we must be neighbours!
Here on planet earth there is a television advert for Churchill Insurance which has a large dog which says "Oh yes!" frequently. Sorry if my miserable attempt at some humour failed.
Oh yes!

LOL, oh gottit!!

(see, I told you I wuz fik!)

By de vay, I looked up . . .etc and inadvertantly re-found the old A320 AOM.

Thanks once again . . .!! (on a Sunday too! . .shocking . . )
