I'm not sure I understand your question. Firstly, there is a substantial difference between the way the center tank fuel behaves on the 319/320 and the A321. Secondly, what do you mean by "wait"? Are you talking about during the fueling process or during flight?

Hi,
What do you mean by gravity feeding?
Check this: Fuel Control Panel | Fuel Mode Select Switch
Could you please explain this? For the A320 or the A330 if possible!

Thanks,
But what is the story with the center tanks which will have to wait for 5 minutes or something like that? I dob't understand why there is no fuel in the center tanks during tge flight...

Your questioning is starting to become annoying over details that were mentioned in the notes that you displayed.
I will answer a question but you should go to an Aviation School and learn some very basic concepts to help yourself here.....
Centre tank pumps will run automatically as mentioned until the pumps low pressure is sensed, fuel card logic will switch these pumps off after 5 minutes to prevent damage to the pumps.
MAN selected you have control manually of the centre fuel pumps
FAULT the centre tank still has fuel when it should be empty as comparing to the level of fuel in the wings at that moment.
Crew action, I think, would probably be to select MAN and manually pump the centre fuel. Cockpit observation would possibly have detected this inbalance before the FAULT appeared.
No fuel in centre tank, engines have used that fuel earlier in the flight, if centre tank fuel was uplifted.

Absolutely, Tinwacker, and it is a site-wide moderation issue.
There are two forums where folk like AF330 and EINULL should be - Spectators Balcony (Spotters Corner) - PPRuNe Forums and/or Professional Pilot Training (includes ground studies) - PPRuNe Forums where the forum headers say it all. Dealing with ??13 yr olds?? (or ??trolls??) who claim to fly Airbus or 'anonymous' users providing no clues here is a waste of time, and on those other fora most of us, myself included, will be more than happy to 'point' genuine posters in the right direction with answers or links. This endless series of 'questions' is a total farce, mostly all solvable with a search engine. If you recall we had that awful 'SSS' or whatever he was called a while back with similar postings (remember his 'reduced power' saga??) until eventually I think JT 'sorted him out'.
These are certainly not 'the best in practical technical discussions on the web'!!
