Flaps during transit A320

[Stone_cold]

TP.

Seems that I assumed that as this is in the after landing procedure , all hydraulic systems are functioning . If one wants to select "slat only " at the gate , yes, I agree that it is possible , not usually a recommended crew procedure , but possible .

I don't think there are any updated sensors as the 30C recommendation is applicable to all aircraft. Perhaps the company may be preferring occasional wing bleed warning by retracting flaps to the possibility of damage to the RTLU by leaving them at 1+F.

Yes there are and the limit is not applicable to all aircraft. Our aircraft had the 30 degree limit. But about 7 years ago, they were fitted with new sensors - and now we don't! I do notice that other operators have new A320s and leave the flaps at 1+F during transits, so they are obviously an option.

Even 2014 FCOM states the same 30 degrees for all aircrafts. Can you check your own FCOM and confirm? What you see may be airline practice. It is not a mandatory action just an advice so obviously it can be ignored.

No they don't. FCOMs are sometimes adapted to airlines and of course only apply to the airframes specified in the applicability list. Our FCOMs are particular to our operation and had the requirement for 1+F in OATs >30 degrees removed once the entire fleet had been modified.

It also depends if you have a large number of pilots in your airline who came from other airlines where the slats were left out.

Some people have difficulty in adapting to a new employers SOPs

Dan,

Could you provide a reference to that modification?

[Dan Winterland]

I had a look in our FCOM for the reference, but got bored after about a dozen pages. It's in there somewhere, it will turn up sometime. I gather the new sensors have better sheilding.

I checked FCOM of an airline which has aircraft with sharklets and BUSS which have new FWC H2F6 even that has the same advisory.

Operating in Australia we don't do it.

Only ever had an ecam when it was over 40 degrees.

From engineering, having the slats in config one allows better dissipation of hot air.

I'd rather an ECAM than a fuel truck smacking into the trailing edge of the flaps......

Yes that is the reason most air lines don't do it. The refuellers are used to the usual clearance under the wing and may not realise the changed situation. Besides it is only a possibility of warning and a suggestion. But sensors are same there is no modification. Dedicated airline FCOMs may have had it removed altogether.

If the wing air leak sensor is not triggered until 124 degrees centigrade, then does anyone know why the caution triggers at 30 or 40 degrees?
