I'm glad it's clear to AA, 'cos I'm still a little puzzled.
Every non-precision approach terminates in a visual approach once the necessary visual references have been acquired. Are you saying , Niknak, that if the runway is classified as "visual only" then the RTR for the SRA must be 2nm minimum? Can you point me towards a reference? Because, of course, some SRAs terminate at 0.5 nm. These would presumably only be to an instrument runway.
