How do I change the items (airways, airspace, etc.) that are displayed on the Data-Driven Global Aeronautical Map?

To change aeronautical items, such as airways, airspace, ARTCC boundaries and more, tap the Maps Settings button  at the top of the Maps page.  From the pop-over, scroll down to the AERONAUTICAL section and adjust the settings to match your preferences.
