oryxbollocks, that's right we actually didn't specify which conditions we are talking about. There are generally two scenarios:
1. GS interception from above using V/S dependable on the version 332/333 you have the choice whether Flaps 3 or full, like the procedure in Kathmandu. I am not very familiar with that, but from what I have heard that's what the folks on 320 are doing there. In normal circumstances you wouldn't need more than 1500 ft ROD.
2. Just killing the excessive altitude in Open Descend mode. That would be than on 332 Flaps 3 gear down speed 180 KT. Although I wouldn't really like it, since its not a very pax friendly maneuver and exposes you to the danger of exceeding the company ROD limitation.
Cheers.
