Hello, I flew today from LFBO to FAOR. Started my trip at FL310, then 330, 350 and finally 370. I noticed that whatever the cruise altitude was, the cabin altitude remained constant at 5320ft. So consequently the Delta-P raised at each step climb. When reaching FL370, the Delta-P value appeared amber. Shouldn't the cabin "climb" at every step climb to maintain the Delt-P within limits ?

Also noticed that the CAB V/S always shows +/-50ft/min even if the CAB ALT remains steady. Below is a screenshot taken at FL370. I also send you the latest autosave file.

Hello,

Apologies for the delay. Forwarded this to the team.

Thank you 🙂 

I wonder if the bug could be related with the AUTO STEP CLIMB option on the EFB. A  friend has the option activated and never had pressurization issues. Mine is deactivated, cause I always set the STEP ALTS in the FMGS after reaching the TOC, and I always have my cabin altitude remaining steady during the whole flight, even after 2-3 step climbs.
