The program creates a visual preview of the route overlaid over a VFR sectional or IFR
enroute chart, which also has weather overlay.
But then the bubble bursts if you happen to get around to tapping for the
enroute chart to peek at where it takes you.
The same three letters--MTA--had me feeling a nickel short when I first saw them on a low
enroute chart. We learn in our IFR infancy that the minimum enroute altitude (MEA) along an airway might get trumped at a fix where there's a minimum crossing altitude (MCA) or a minimum reception altitude (MRA).
The
enroute chart shows what looks like the same hold and intersection with the Eagle localizer on V361.
During the comparison exercise, the gotcha only became apparent after seeing examples of look-alike missed approaches and then asking the right questions and checking the
enroute chart.
If you're concerned about the size of the files and overall storage capacity, you have the option of downloading all of the required data (tapping the Pack button) or by separate line item (approach chart,
enroute chart, etc.) by tapping each line item on the page.
MON VORs and airports will likely be marked on your

Bonus: What are those the brown lines that pass through the area shown on the
enroute chart?
