So....the Avionics Bay door sensor, which is in no way is associated with the control of the Packs, knocks the Packs "offline"...? The Pack is an almost purely mechanical device that is controlled by 2 Pack controllers, which have 2 channels for redundancy and no input from a door sensor. I'd hazard a guess that they got an ECAM stating the Avionics door not closed, so decided to then make a precautionary Emergency Descent, or maybe a better term of rapid descent, I really don't know, but there is no way that that warning would affect either the Packs or the CPC's and so on.
And Hedo, some of the CAD fly as pilots with HKA as no other outfit would have these halfwits anywhere near an operating seat, so don't hold your breath for HKA to be shut down anytime soon.
