In the UK, a major difference between ATC and AFIS is that with AFIS you're only allowed one aircraft on the runway at a time whereas with ATC, It's possible to have more than one. All the PFA Rallys I did were ATC and we had procedures to safely manage multiple landings whilst keeping 2-way RTF to a minimum.
