I've never flown an airbus, but I cant see why it would have any more problems with a go-round than another "old" aircraft such as a 747 classic. All aircraft need time to spool-up, and all aircraft have huge amounts of inertia.
From the peformance manual of a 767 with CF6 engines are the following altitude losses expected during an automatic go-round. I would expect that the loss would be greater during a manual go-round due to us dumb pilots.
Altitude ft/Loss ft
50/39
40/29
30/23
20/15
10/9
5/5
So even if you initiated a go-round at 10ft you would not touch the ground.
Does anyone who flies the A300 have their figures?
As far as I'm concerned if the tower tells you to go-round you do it, a quick touch of the ground during a go-round is better than a quick touch of another aircraft on your runway!
