From a 330/340 perspective! 160kts to 4nm in a light 330 ( as is often the case on the short ME sectors with low pax loads ) is just asking for trouble and I will always decline this instruction. The 343/345 it is generally not a problem as they are no where near as "slippery" as the A330.
The 500 feet should not be a target for being stable on every approach into Dubai which i seem to think some of the previous posts are hinting at!!!
Good thread nice to see something sensible being discussed on pprune
