John You do have a point - but, actually, there is a much wider one that IACO could consider: that is, in such cases, could those in the cabin area be provided with a system whereby, in cases where the cockpit gets "taken over", it could allow them to communicate with the "someone" "somewhere" to alert them of the problems - but it would still not prevent the person still remaining in the locked cockpit to do whatever they want, unless a "remote unlocking" facility is incorporated. Again, maybe in the future, and then again subject to all the communications-related issues mentioned in my first post on this subject.

I'm sure that isn't what was meant. The ground control would operate only in exactly the Germanwings emergency case - lockout of an officer due to the other officer being mentally disturbed or having, for example, fainted and fallen on the switch. It does require the locked-out officer to be able to send a suitable Mayday, but that's not so difficult. Even so, I think my proposal for lockout being invoked only by both officers is simpler and possibly more reliable. -- OOO - Own Opinions Only. With best wishes.
