I disagree. At some point an approach has a visual segment unless you are going to autoland in low visibility. Airbus has recently changed the minimum height for autopilot disconnection after a non-precision approach but on a cavok night the temptation would be to disconnect the autopilot, select the Bird ,align with the runway centreline and fly the papis by looking out the window. The problem is that if the visual picture is confusing with lots of lights on the airfield environment and the lights of the city beyond, there will be nothing inside the aircraft to tell you as the ILS will not have been tuned by the aircraft.
With a non-gps aircraft the map on the ND would could also have a small error.
Perhaps as part of the approach briefing the threats of the runway closure and what the correct visual picture will be for landing could have been discussed.
Gatwick has two strobes on the runway threshold when the standby runway is in use, and nobody is allowed to occupy the parallel taxiway.
