So why is everyone on this thread referring to the localiser?
No clearance for an ILS approach has been issued
Because it’s the most accurate lateral guidance. (Yes including the Mk1 eyeball)
If we didn’t use the Loc, it would leave very little options for automation should you still want to use it. It’s a visual approach, whatever tracking guidance the crew choose is their choice, but they need to make sure it contains the aircraft within the IVA tolerance which I’m certain a LOC would.
16L for example, can be cleared way out. If we didn’t follow the loc we could only do it in HDG (shudder) or switch everything off and do it visually which is fine, but not always appropriate.
