ANV FILE EXTENSION

How Do i open a .ANV file?

I don't think you can. The only way I have found to view them is to subscribe to and use the parent program "AirNav VFR".I have tried to find something to convert .ANV files (which are AirNav VFR's Map Files of the Australian AirServices Aviation maps) to some other format so I can add data (like airspace boundaries) to the WAC Maps (topographical maps) so I only need to use one map in flight not switch from one to another etc.Doesn't seem to be possible (but I will keep trying.I emailed the program author once about it and he said it was a requirement of Air Services that to let him use (and AirNav VFR customers pay royalties for) their maps, the files had to be un-decryptable.Purely money grubbing by CASA and/or AirServices - they want you to pay for the maps you are required to have (even if you don't really need them for your flight)but not to be able to modify them to make them more useful. Makes you buy more than 1 map for each area you fly.Even though I have paid for the maps with my subscription and I feel I have a legitimate use and idea to make them easier to use it is still not possible - it seems.I will be happy to be proved wrong though :-)
