When I was in ATC at HK,a visual approach was a real no-no.All approaches had to be ILS,or VOR/DME.
I could never understand why,as CLK is so easy to find.What was the problem with a visual to 07L/07R?
Where I am in the UK we use visual approaches all the time.You provide the a/c with IFR separation,or they become visual with the a/c ahead and you advise vortex spacing.
Mind you there were a lot of things about HK ATC that were puzzling.Must have been a Kai Tak hangover,but they did visuals there.
