Visual Approach Separation in the US
It seems that at major airports in the US, traffic runs much more smoothly when the weather is nice. I think this is due to the prevalence of Visual Approaches being flown. I'm confused: since we (the airlines) are all operating under IFR, don't IFR separation standards still apply?
If a controller could explain to me why traffic moves much quicker when Visual Approaches are being conducted, as opposed to when it's low IMC, I'd be very grateful!
Much thanks,
Mike
