a Boeing Tech Rep came to visit our company for an annual road show. It was stated that since the Helios Crash that there were planned changes to the pressurisation system in the pipeline with "Voices and Flashing lights" instead of, and perhaps in conjuction with the Cabin/Config. horn.
This is happening. There will be two new red lights on the P1 and P3 panels one labelled "CABIN ALTITUDE" and the other "TAKEOFF CONFIG". These will illuminate whenever the associated aural warning sounds.
AFAIK there will not be any voice warnings, just the same old intermittent horn.
