Airbus flap/slat retraction after engine shutdown
hey all!
I was wondering if there exists a procedure for flap/slat retraction after engine shutdown.
If OAT is greater than 30°Celsius we keep 1+F, but sometimes we have to retract them again for fuelling. I know this is done by putting the Y elec pump on...but is there also an FCOM procedure (I can't find one).
And another question, can this kind of procedure cause a Flaps/Slats SYS fault?
Many thanks in advance!
Grtz

Only using yellow and green (via PTU) causes system fault.

Thanks! And could you tell me why this is? They're - I thought- perfectly retractable via Yelec and Green (via PTU)...
And the slats failure, is it then resettable by recycling the flaps/slats?

there should be a reference in the fcom in the cold weather section where it has the procedure for retracting the flaps if they've been left down for inspection after landing on a contaminated runway.
found the ref.........fcom 3.04.91

Only half a speed-brake
FCOM asks for Slat 1 for pack cooling. Invariably, you will end up with 1+F when on ground which scares the refuellers now and then. I believe the difference lies only with the FCOM choice of words, and is not really important.
But, is there a way to get 1+0 on the ground?

I think you mean config 1 (1+0=0)
If you use only blue hydraulic and set flap lever to 1 you get slats 18° and flaps remain at 0°.

Ommitted the quotes on "1+0" 
but still 1+0=1 
.... couldn't resist, sorry
Didn't think of it as normally I do not select B to OVRD and bear with the Slat Fault indication - which contravenes the FCOM 2 procedure as I learned today. Thanks anyway!!!
Nice rule of thumb I forgot to use before asking is to write the system colours alphabetically and then imagine a wing devices profile: BBG-GYY
front -> slats -> B&G, aft -> flaps > G&Y.
No G or Y, no flaps. Need to think harder next time.

What is the reason behind setting 1+F?
Hi all,
I was going to ask this question as a new post, but this thread seems as good a place as any for it.
On arrival in Phoenix a couple of days ago after landing, as pax, I wondered why the flaps weren't returned to up after landing. I pick up on these kind of things being a bit of a geek. I duly made a point of looking at the other parked "Airbii" and noticed the same config on all.
At least you've cleared it up that it's an Airbus procedure to set Flaps 1 when hotter than 30deg outside, but what's the reason for this?? I have a few ideas but won't bore anyone... It's been bugging me now for the last few days!
Thanks,
Spr K (retd.)

Extending the LE improve the circulation of the air around this area and reduce the erroneously warnings.
