thanks 407, i didn't know how to do that.
nigel,
the aip and the training manual used to say that night vfr was flight at night under the visual flight rules with navigational reference to the ground or water at all times.
flights on a moonless night with any degree of "celestial" illumination is inherently dangerous. not having a sas or proper instruments for inadvertant flight into imc seems to be asking for trouble.
there are a few couple of companies in australia that do marine pilot transfers under the night vfr up to a hundred nautical out over the ocean.
more guts than an old bloke like me.
