Default How long to get down question

I was a passenger on a flight from Atlanta to Orlando in a 757.
About half way, at probably FL 310, passengers and crew detected
smoke in the cabin. Spoilers came out full, gear stayed in. We
pitched down and headed for Jacksonville. JAX was probably 40 - 50
miles to the east of our course, but we landed in less than 10 minutes
and were met by the equipment.
The smoke turned out to be coming from a short in the 'crew computer';
the system that kept track of crew duty time.
I'm not sure if we hit 10000 fpm descent, since we also had to cover
about 40- 50 miles laterally, but we were getting down fast!

That brings up the question of how long that time really is....

If you are at cruise in Boeing's finest at FL430 & declare an
emergency; how fast CAN you be down and stopped? (Or Airbus, for
that matter....)

Assuming ATC can clear a lane, I assume it's a function of how
steep a decent you can use without exceeding the max IAS. What are
the limits on speed brakes, dropping gear, etc. to dirty things ups?

Do you slow to gear-down speed, drop them, then nose over? Or is
the higher speed possible w/ gearup better?

Getting down is not a problem.


You're right, hence aviation's perfect record of never leaving one up there.

If I need to get on the ground that fast.. screw the "pattern" and taxi
time.. The descent will be planned to have me on final and "configured" for
landing.. I'll stop on the runway or turn off and shut down.. the trucks can
meet me there... screw "taxi"...

If you are directly over the airport you can land at, then follow the
emergency decent procedures for that plane (and they differ from plane
to plane) and come down about 2000 fpm (I really don't know, and it
would depend on the plane), but lets use that figure. Then it would
take 21 1/2 minutes to get down and maybe 1 1/2 minutes in the pattern
and 1 minute of taxi, so that is 23 minutes, assuming the airport is at
sealevel. That would be fast.
