Hi all,
Thanks for all the detailed replies, very much appreciated!
The thought of a very high MSA didn't even cross my mind!
That would be a most inconvenient place to lose cabin pressure, of course there aren't that many convenient places.
So if you were to descend using the auto-pilot, would you use lvl change and set speed to VMO and adjust as you descend? My guess is this would may be the best option, only a guess though.
Thanks again!
