A320: Can RAT deploy on Take Off?

[aviatoraj320]

Can anyone help, can RAT deploy on Take Off on A320?

Yes if your performance is marginal and you could use an additional 1% takeoff thrust you can deploy the RAT by giving a double click on the side stick red button.

Oh..

I thought it would deploy to find out some friend on the runway (may be another RAT)..

Let me just tell you; this question was asked in a interview. Every time it is not a joke.


P.S. No hard feelings.

A320 has a RAT??

[OMGisThatJohn]

My FCOM doesn't say it can't.

If AC Busses 1 and 2 are lost over 100kts it will extend.

And fuselage flexing on rough runway can cause "Rat unlocked" message,on some types..

I also can't find anything that would suggest it can't.

Automatically - No, Manually - Yes.

For automatic operation you need an 'in flight' signal from LGCIU 1.

Jet II,

First of all thank you for providing some right direction to the post.

Manually, I understand 'Yes'. But automatically it takes signals from LGCIU 1, is it written somewhere in the FCOM? Can you provide some reference?

Its in the Airbus Training Notes

Very nice information.

Thank you once again...
