Yes, apparently. There is an advisory linked to a "cabin vertical speed", related to the ECAM presentation... It indicates a cabin vertical speed in excess of 1800 ft/min up or down, translated on the ECAM screen as a very small green-pulsing bar.
A depressurisation would have been indicated by an "EXCESS CABIN ALT" warning, telling of a cabin above 9500 ft....That warning is not part of the received ACARS messages.
- picking up on just this one part of your reply - if only we could be sure we have ALL the ACARS messages in sight, then there is a very good chance we can rule out a high-level break-up in view of the lack of an "EXCESS CABIN ALT" warning as you say. Without such a signalled disruption to the cabin pressure, the only subsequent ACARS message must surely refer to a descent? Dare we surmise? PJ? Bsieker?
