Is it possible? (US Airways flight)

[Deli Guy]

Maybe that's what the "idiot" comment on the ATC tapes was about.

"Idiot...you shut down the wrong engine."

Or not....

Where was the "idiot" comment?

I dunnno. I'm hearing "88" something... not "idiot." Maybe a call sign with 88 was being addressed by another controller in the background.

After 10 years around jet engines, you may be correct. Besides, I used to listen to Ozzy Osbourne albums in reverse as a kid. Who knows what the heck I am hearing these days.

what would the N1 rotate at while just windmilling with no power in a glide?

 

[b707guy]

Depends on airspeed and altitude. Mid teens to low 20s N1 down near sea level and below 250 indicated.

Oxlong - you mentioned you observed 38% N1 as ground idle? Was this on a CFM-56? I haven't flown the newer series CFMs, but my experience with the older ones is that they should ground idle at around 21%, and flight idle on the ground (before "shifting" down to ground mode through whatever means the airplane decides it's on the ground) is closer to 38 or 40%.

That's what I see on our CFM 56's. Around 21% Ground idle, around 38% Flight Idle, Approach Idle is a little more.

I'm no expert...but, if I have two ( out of two ) engines flamed out, the " engine shutdown" checklist might not be my first choice.

I might go with some crazy sort of attempt to "restart" and see if I could find a checklist that said something along those lines.

Oh, I would probably also be swearing a lot, and my head would be swiveling around quicker than Linda Blair's while I was looking for the crash site I was going to be visiting in the next few minutes.

No Sirs, I don't think Sully and Skiles were busy shutting down any engines that day.

Let alone..."The wrong one".

DOH.

Yes they did try relighting the engines.

Food for thought:
1. Where were the thrust levers?
2. What vertical mode were they as far as auto flight?
3. Could the AT have commanded IDLE while they were descending?
4. Could they have mis-diagnosed the IDLE reading as being a failed engine?

Bottom line I hope they continue to be heros.

"Yes they did try relighting the engines."

Ya. I know. Of course they did. And rather rapidly I would surmise.

However, I was responding to the original point of this ( as usual ) inane thread:

" Did they shut down the wrong engine? " (NO.)

My point being:

Shutting down an engine wasn't even part of the thought process in that cockpit.

( Unless, perhaps, they had a fire going, then securing it might have been a thought. Even then, why would you bother? You'd have to your advantage a very nice fire suppression system ( The Hudson ) in just a few moments anyway. )
