incredible thread
it never ceases to amaze me the so called experts we have working on aircraft these days.
you are looking on a forum for information on a fault that the OEM does not have any knowledge about.
the a320 is flying 20 years. airtac know their stuff.
i think as maybe the answer from airtac was negative you failed to use the TSM properly as this would be the first reply from airtac.
there is more than enough information available through SILs TFUs and the TSM to easy solve this issue. i suggest you explore them.
and flame bringer for a person of 22years old you are an accident waiting to happen. learn how to use the manual and also try to understand how the aircraft works. it is clear neither you or the people that are working with you have no idea how to use the manuals.
learn how to fix problems not how to reset them.
and lastly never dispatch an aircraft with a no dispatch message unless you have fixed the problem. otherwise you might kill people!
