I still don't understand how the night=IFR bit is reconciled with all those non IFR certified planes/helis flying around at night.
Presumably the same way when they're flying around UK-style IFR during the day?
It seems the rest of the world interprets the term Instrument Flight Rules to mean plunging about in cloud using Instruments to find your way. We interpret it to mean keeping our distance from fixed objects and each other, but quite possibly being able to see out perfectly well.
It's a funny old game.
