1: Ask ATC for "the crowbar"
2: Get cleared direct to the initial approach fix to intercept the ILS
3: Deploy the speedbrakes
4: Slow to maximum gear speed and deploy it
5: Descend with 4500 ft/min
6: Hard right onto the ILS while slowing down
7: Land and remember your C17 days when you could use reverse in flight and really drop it.
Or do you get these descent rates with just spoilers on an A321?
