We've updated our system to add the new NOOK Simple Touch Reader as an ePub option. The available height is the same as the older NOOK but we can now use full screen width. So we get a bit more space to put the Approach Plates, AFD and converted books on.
Much like the NOOK Color, you'll need to tap the center of the screen, choose Text and make sure "Publisher Defaults" is checked.
And of course, our FAR and AIM from the B&N Bookstore work fine as well.
