Tigger too

The point is that you need pressure oxy to sustain activity below 80mps. For shortish periods you can easily work efficiently above 10000 cabin alt. I have personally experienced 15000...

Yes there is. Not sure which but you're not sure of.

In an IAS/Mach Idle descent the VS and thus vertical path will vary with wind, temperature/density changes, vertical currents, IAS/Mach...

It would issue an alert and then a hard warning in all probability. The exact mode of warning would depend in circumstances. Doesn't do anything else at all. That's left to the pilots.

I think it is safe to discount the creeping depressurisation. There are several warnings that would alert the crew to this in good time. As posted earlier, at least one of these is effectively...
