In the meantime, a public education program for pilots about the hazards of night visual approaches from circling procedures seems like the only viable option.
Consider me as enrolled in the program. Thank you all for your postings here. It really has got me off the couch and into the books for more info on this topic.
I've taken
night visual approach from circling procedure out of my bag of tricks for the time being. At the aerodrome I mentioned above, the circling procedure is fine during the day...at night, I'll use the other resources and options available.
