How can I view Caribbean, Mexico, or Central America charts?

First, please verify that you have properly downloaded the desired charts prior to your flight. To do this, go to More > Downloads > Caribbean, Mexico, Central America and make sure either IFR Low Charts, IFR High Charts, or World Aeronautical Charts is selected to on.  Go back a page and then tap the blue download button to download them.  For more on downloads, please see the ForeFlight Mobile Pilot's Guide.  

Next, you just need to select the chart that you wish to view from the Maps Selection pulldown in the top left corner of the Maps page.
