Hi takata,
Quote from takata (Today, 0545z):
“This alert may be related to purely sensor/ADIRUs errors; it may be related to a real aircraft descent rate above 1,800 ft/mn from whatever altitude (in case external pressure is still feeded to the controler by another circuit - but whilch one?); it may be related to crew actions during troubleshooting...”
Can you explain what “external pressure” has to do with cabin pressure (cabin altitude) and cabin VS? What am I overlooking?
Alternatively, why would an ECAM warning of excessive cabin VS be spurious? The creation of the warning implies that cabin pressure data were still available. That being so, what would cause them to be corrupted?
