I read a recent review of the new gulfstream that the autopilot
automagically descends if presure is lost.

A lot of new aircraft have this feature. Cessna has been doing it for
years on Citations. Engine goes to idle and it will decend and level
at 14K. That will work fine unless you're over the Andies.

Is it TWAS coupled?
