How long to get down question

Most jets can descend over 10,000fpm. Getting down is not a problem.

An OT query for folks here. While discussing things that can happen
between the jetways, I posited that it's a really bad to be aloft
in Big Iron in a medical emergency, etc. -- based on how long it
takes to get on the ground.



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

So:
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?

Ah, ok. well at 10,000 fpm, wow can that really be? It would be 4 1/2
minutes (rounding a bit), still about 1 1/2 minutes "in the pattern"
(you need some time to level out, slow down and line up) and 1 minute
to taxi, giving 6 minutes. That would be REALLY fast!

Yup, 10,000fpm is 100kts *down*. I think a lot of jets will do *well* over
10,000fpm. My MU-2 will do almost 6,000fpm in a straight, clean, power off
descent (no bank) and 10,000fpm in a slip. Keep in mind that many jets can
*climb* 5,000fpm when lightly loaded.

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