DL 767-300 decompression (DL 2353 9/18)

Looks like it took them about 6 minutes to get down to 10,000 ft.

Ignore the silly drama in this article:

Seems like it was handled pretty well... though 6 minutes seems a bit casual...

Am I reading this correctly? They still made it to their final destination 12 minutes early?

EDIT: disregard this, for some reason FA doesn’t show it as diverted.

It was originally planned for FLL.

I can assure you, it wasn't casual. That's the average ft/min descent rate during each time frame.

If the article is to be believed, they went from FL390 to 10000 in 6 minutes. That's nearly 5000 fpm. What kind of rate of descent were you hoping for?

As long as the aircraft gets down before the oxygen in those face masks runs out, not a whole lot else matters. Doing the descent faster than necessary risks injury, for example someone whose seatbelt isn't fastened could hit the overhead panel with one's head.

Also risks damage to the plane and engines if rate of descent is too high.

from what I remember of 767 flight test work (~1981, so not really guaranteeing accurate recall), 5-6000 ft/min is the emergency descent rate

All these posts lately saying I should hop onto DL for a better experience than AA, should have mentioned you get a free Halloween Terror Ride with your base airfare - I'd sign right up

Interesting though. Curious to see what all comes of it.

Big issue with rapid descent is avoiding overspend which factors into the max VS. I believe they set the auto speed to the max, open descent and close throttle, basically allowing the auto pilot to descend as fast as possible while maintaining max speed

Are you saying the 767 isn't rated for a tactical decent like a C-17?

(Speed brakes deployed and thrust reversers engaged allowing 20K ft/min)

Was this a domestic 767? Haven't these birds been retired?

Once they get down to 8,000 ft or so there isn't as much of a rush.
