People have been wondering, yes, both of the Apple approved external gps units work well with SkyCharts. Read more here.

If you in the ‘i’ screen have (null), or a very blank looking page, please don’t try to download, it will not work. Something went wrong in the migration process.

In that case you must delete and re-install the app. Please see Q9&Q10 in the FAQ.

Fix when updating from old version of SkyCharts.

v2.6 adds AirPrint.

This hasn’t made it into the documentation yet, but you can tell the difference by the different SUA’s by looking at the color.

RGB: Red/Green/Blue. 1.0 is as bright as it gets.

In summary: the more RED the dot is the less you want to go there.

#define RGB_WARNING 0.6, 0.0, 0.0
#define RGB_PROHIBITED 1.0, 0.0, 0.0
#define RGB_RESTRICTED 0.8, 0.0, 0.0
#define RGB_ALERT 0.6, 0.0, 0.0
#define RGB_MOA 0.4, 0.0, 0.0

v2.5 adds SUA (Special Use Airspace) information, High Enroute IFR charts and some additional WAC charts to extend sectional coverage charts.

Reviews for the new region select has been less than satisfying.
Remember: Its trying to download a LOT so make sure you use your fastest connection possible. In most cases that should be wifi, but if you know your wifi broadband connection is slow, please try 3G as well and check which is faster.

It should take about 7 minutes to download 450Mb, and about 14 minutes for the 900Mb.

The first download bar is download, the second bar is unzip. If your wifi is faster to download than the unzip process the first bar should move faster than the second bar.

Don’t take the app offline until both bars are at 100%, but you can safely take the app into no connectivity areas after the first bar has completed.
