Aeronautical Charts

for iPhone & iPad


Even if aeronautical charts are 60 by 20 cm wide, we’ve noticed the fine print is really really fine, that or the chart is a scanned TIF image and it is 64 mega-pixels in size.  As you’ve seen most Apps in the store grind, and you count to five waiting for a tile to redraw, scrolling, forget it.  We avoid all that giving you the best user experience.

If you chose to email or access the charts via Safari, or have them stored in another PDF reader, then just check for the "Open In..." command in your Apps, via tap and hold on a PDF document icon and choose Aeronautical Charts.

For TIFF files, those require a bit more effort as Apple makes it hard to move them, see

Or move them into our app via iTunes file sharing
