am working with Airbus 320/321. I see a problem relates to residual press on ECAM shows 100PSI even when Blue sys is depresurized. Does anybody know why?
I'd tried to replaced transmitter 02 times and did measure wiring as well but problem sounds existed. FCOM just says limitation when presurization is 3000+/- 200PSI. Capt always complains this althought i see this sounds ok for dispatch a/c.
thanks for your support.
