# What is the minimum separation between two landing A380s?

I have always assumed that landing separation depends on wake turbulence limits depending on weight class.

However I see that no minimum separation needed for the A380 as trailing aircraft (and in a few other cases): http://www.ais.gov.hk/HK_AIP/aic/AIC22-12.pdf

In practice, what distance or time separations used in these cases, where wake turbulence isn't the limiting factor?
