335 KIAS, 13 nm. It won't be pretty but it can be done.
3000' AGL? Huh? "It's hard to go down and slow down".
How about 1500' AGL, until the 'drag required' point. At that point start climbing (ramping uphill) to slow faster. Full speedbrakes, gear at limit speed, flaps at limit speeds, idle descent for glide slope. You'll be at idle through 500'..
Like I said, it won't be pretty but it can be done. I'd plan max speed to 15 nm and 2000' AGL max. Not as ugly, still a max performance event.
Now lets say it happened at max cruise altitude. Oh, things just got a lot tougher. Max certified altitude with emergency descent to a max performance arrival (see first paragraphs) to stopping on a runway is approx. 9 minutes and 60 nm. So the 10-12 minute window does not have time to spare.
No, this is not something to practice in the airplane.
