To be fair though - how many enthusiast databases are there out in the open , that don't require some sort of subscription to receive regular updates to databases?
I understand the need to frequently update the db initially provided with the purchase of software and hardware, so in that context , it's a fair point.
Given that at present, the updaters are volunteers, and are undertaking a mammoth task, I think it's only fair that the fruits of their work are passed on , on a regular basis.
If AirNav did go down the professional route, in involving some commercial venture to provide the info, from admittedly a more accurate data source, then I also think it's a reasonable expectation to pass the cost on, if regular updates are issued?
For the time being, we've got a welcome platform to now move forward on, so let's get behind the team and help them further improve things?
