pss airbus fuel

[abd zibdeh]

i fly pss a320 a330 a340 for a long time and in most of my flights one of the fuel tanks becomes lower than other(s) and there's no fuel leaks , i
tried to turn on the fuel xfeed but nothing happens .
is it that the pss didnt configure the fuel x feed button?

How much difference is there? Just a few kg?

turning on the x-feed valve alone does not do the job. you also have to disable the pumps of the tank which has the lower amount of fuel
so the heavier tank supplies engines with fuel. once balanced kick in the regular pumps and turn off x-feed and you should be set..i do
use the pss 320/330/340 too but never noticed any fuel imbalance so far...you may be right with your assumption that the x-feed is not
simulated but i doubt that...

some flights its about 100 kg and sometimes about 1000 kg

That's really a lot, didn't notice that much difference before. Is it the original air file en aircraft.cfg you're using?

[abd zibdeh]

i remember that i changed the air file ,i downloaded it from the pss user edits website

[Dutch64]

Maybe you've use an airfile for a different pss plane? Try restoring the original and see how it goes

[abd zibdeh]

its not for a different one ,its to fix the auto landing elevation problem

[Dutch64]

Fuelflow is done in the airfile and/or aircraft.cfg. So, if something in fuel flow is wrong you should look in that area. Just try swapping those
files with the original ones just to see if it makes a difference.

Why don't you ask PSS? oh, hang on... PSS are no longer.
