320 flap limitation
 

Can we fly above 20,000 ft with flaps extended?

I mean thet are extended Below, but then we climb to, say, FL 260.

Is that possible according to limitations?

Non monsieur.

Agreed,

The FCOM clearly states the limitation:

:)

Certification compliance consideration. Nothing specific to Airbus. Several threads on the subject in times past as, for example, here

It was done recently J_T, in an airline near you. That's probably why the question came up.:uhoh:

You will get an ECAM at FL210

Thanks, guys

Now re-reading I see that it is crystal clear: you cannot operate the airplane above 20,000 ft with slats or flaps extended.

and now the next question:

what about landing gear?
Can you extend it below 25,000 and 250 kt and then climb to FL280 with the gear down?

Here the english is not so clear to me:

I'll take a look at that thread, J.T, thanks

I suspect that the non-investigated Mach considerations will apply to gear in a manner similar to flap. The basic rule of thumb is that the OEM isn't going to invest money in certification for altruism - the aim is to make dollars.

OS, what was the story there .. in a de-identified sort of way ?

Would very much like to hear the story behind that as well. De-indentified if necessary.

Oops.

Gear is usually a Mach thing. A mate of mine, when he was young and foolish had to ferry a Lightning with the gear down. Faced with a slow flight, he decided to climb high to get the TAS up, forgetting about the Mach lmit. Apparently, a Lightning doesn't do Mach 1 well with the gear down!
