Someone said a visual approach is just that, and ground avoidance is pilot's responsibility until over the black stuff. A lot would depend on the a/c type and wheel depth below eyeball. It would also depend on the dispalcement. RWY 33 at Madid where the displacement is 3500', it works well to fly the G/S to low level then adjust to touch at the threshold. The slide below the G/S takes place over the runway, so no obstacle can be interferring. It can also be done without de-stabilising the approach.
If the runway surface was suspected of not being excellent braking action, why leave 1000' or more behind you?? Same applies for tailwind.
For legality, is 1 dot low not within IR limits? If so then it should be safe and legal, or else the IR rules need adjusting.
There are airfields where there is no G/S guidance system. What then? or if it is u/s for arrival. Mark 1 eyeball and consumate skill! You'll NEVER get approval in writing.
