USA and canada allow night vfr flight.
Not strictly true, they allow VFR, and do not differentiate whether the sun is up or down. All part of having a PPL and up. Last time I noticed, UK had a night rating and the rather useful IMC rating.
Only in Australia do we insist that such things as night or controlled airspace are somewhere special, and only suitably rated pilots need apply.
Indeed, in the early days of the dreaded NVFR, I was officially advise that my instrument rating did not count for NVFR, apparently I could only fly in IMC, not on a fine and clear night. Only in Australia.
Mind you, in those days, there was no shortage of Examiners of Airmen who rather disapproved of GA IFR as well, just stick to day VFR.
Having originally learned to fly in UK, as I have often said, I didn't know flying was so bloody difficult until I cam home. And little has changed in the subsequent 50+ years.
Tootle pip!!
