Final answer:
Information about MOAs can be found on sectional charts, Chart Supplements, and in the Aeronautical Information Manual (AIM), with sectional charts showing boundaries and altitudes, and Chart Supplements providing usage details.
Step-by-step explanation:
Information about operating in a Military Operations Area (MOA) along your planned route of flight can be found on a sectional chart, which displays the boundaries and altitudes of MOAs. Additionally, a Chart Supplement (formerly known as the A/FD or Airport/Facility Directory), provides details on the usage times and controlling agency. The Aeronautical Information Manual (AIM) can give you a general understanding of MOAs and how to operate within or around them.
