Markjoy, thanks for your reply -- nearly all seems to make sense.
However, I do have a slight concern about switching off the runway lights to signal a "don't land." I don't know the location of your airport but when coming in at night the runway gives pilots a lot of reference once they have transitioned to visual flight. In some places it's the only reference!
Now if suddenly the lights go off in theory we switch back to instrument flight and go around. However, human factors research, and incidents on black hole approaches have shown this is not actually that straightforward. The brain has at this stage been using the outside reference to place 'itself' in the world. Now these lights are suddenly gone and we go-around, completely confusing the senses (somatographic illusion; the accelleration will give a feeling up pitch-up). The brain subconciously tries to hold on to it's references which are now gone. This coupled with the fact that we feel we are pitching up suddenly makes sense to the brain: we feel a pitch-up and we can no longer see the runway -- so we must be pitching up then! In reality we are heading at full-thrust toward the ground.
Yes -- we should be trusting our instruments and we are trained to do so. However, it has failed in the past and sudden change of outside reference is a major contributing factor to this human failing. All of this is why I don't think the lights going off is a good idea. Maybe just the PAPI's if installed, but other than that.... no thanks.
Other than that -- you make perfect sense
