Twenty bucks a year is the best value you'll ever buy! The updates are free and you're prompted to update when the charts expire. That includes Low altitude enroute IFR charts AAND all the approach plates for the entire country. This alone would cost more than twice what you paid for the iPad.
Best,
........ but who's watching the little plane on their plate while flying an approach...yikes! And by the way, Pierre is the one that hooked me on SkyCharts...now I believe everything he says...lol
Pete
I watch my little airplane on the 430W during IFR approaches.
Best,
I guess i'll try the free Foreflight app.
