Hi,

Could somebody explain why the RAT cannot be placed on an area of the fuselage that is unaffected by the turbulent flow resulting from lowered undercarriage?

Is there a specific reason why this is not possible?

All the best,

Jack

Question

Any suggestions ? The RAT being relatively large and the other place for buses is in the Flap fairing (as on big buses) , but on an A320 it's too small....

Can't remember offhand, but...

I can't remember offhand, but I'm thinking there's a way to run the RAT
with gear down. I'm thinking you have to cycle some CB (maybe LGCIU 1,
not sure) and fly at a minimum of 180 KIAS.

Can somebody refresh my memory? I haven't the FCOM in front of me.


Fly safe,

The RAT can also be used to pressurize the BLUE HYDRAULIC system
On the 330 the rat powers the green hydraulic system!

I hear that the R - A - T (I'm manx and superstitous ) is seriously noisey when it's deployed.

There was an incident, sorry donno specifics, when an airbus A320 with a dodgey engine had to deploy it. The flight crew where so busy trying to sort the problem that they forget to warn the cabin crew! Apparently they all thought they were going down and that the flight crew where incapacitated....

sphincters finally relaxed when the captain came through on the intercom
