Does this mean controllers still have a responsibility of separating aircraft under a visual approach? (A comment in a sibling thread mentioned that Lufthansa pilots are allowed visual approaches, but are not allowed to be responsible for visual separation at night.) Edit: sounds like visual approach means ATC do not have responsibility for separation. I thought the entire point of IFR (which – according to you – visual approach falls under) was that ATC is responsible for separation!
