AP on, Idle, boards out, Vmo or Mmo if no damage. With the masks on and 1 person handflying, it's very easy to stop working effectively together and task saturation for both people would be more likely (IMO).

Obviously, no two emergencies are created equal and I'm sure there are situations where the AP is either unavailable or maybe just not immediate enough for the need. Even in the later case, though, if it was avail and once the descent was established, I would prob turn it back on.

It seems the life and death line is drawn more by getting the mask on fast enough than it is by the time it takes to get to 10k or thereabouts.

Is that in the Dash? isn't your max. service ceiling FL 250 anyway?

Keep 'm comming.

(Are you Den based?? getting junior sp*nked a lot last few days?? ;) )

The Dash it is, Just not in DEN. The e-descent thing is more if I'm on fire and need to hit a runway directly below me. Which the dash can do, in grand style.
 
Easy. Autopilot on. When it's crunch time, you want to do everything you can to reduce the workload. Crew resource management means using every resource at your disposal, and the autopilot is a very powerful tool.

Remember, you're a systems manager, not Chuck Yeager. Save the heroics when for when you take your sweetie-pie up in the 172 for a spin recovery demonstration. You already proved you knew how to fly back in your last PC check.
 
Auto pilot all the way. What happens if you're hand flying and then you both pass out? If the A/P is on and 10,000 is commanded, then at least the aircraft will level out at a breathable altitude and you can wake up before you run out of fuel.

The only problem I see with that scenario is what happens when the AP levels the plane at 10,000, and nobody is awake to advance the thrust levers?

Sadly, I think the recent crash in Greece and the Payne Stewart accident a few years ago would seem to indicate that we are more susceptible to a loss of pressurization and ensuing unconsciousness than we'd care to admit. Has anyone out there experienced a real emergency descent and lived to tell about it? Please share what happened and what you did, it would probably benefit us all.

With the A/P on, set 10,000, select IAS mode, power to idle, boards out. Nothing else to do other than deal with the problem. I'd let the autopilot do the work.

I agree. Let the AP do the job for you.
 
Ok.. About 60/40 so far..

I agree. That would be a problem, but you can only hope to have regained consciousness by the time you level off. I'd rather take my chances doing this rather than pass out without the autopilot on while performing a high speed descent with the boards out! I think at that point you'd have a lot more to worry about than the thrust being at idle when you leveled at 10,000!

Not to mention you'll be putting on your O2 mask and declaring an emergency at some point. Who's flying while you put your masks on?
