Can you legally fly through an MOA (Military Operations Area)?

Flying through a Military Operations Area (MOA) is indeed permissible under certain conditions, making the choice of checking for ongoing military operations the correct approach. An MOA is established to segregate military training activities from non-military air traffic so that military aircraft can conduct their operations safely.

Before entering an MOA, it is essential to check for active military operations to ensure that you are not intruding on training exercises that might involve high-speed maneuvers or other activities that could pose a risk to civilian aircraft. This can typically be accomplished by contacting the appropriate flight service station or checking relevant NOTAMs (Notices to Airmen) for information on the MOA's status.

The other choices do not accurately reflect the regulations regarding MOAs. While it is not prohibited to fly through an MOA, doing so without awareness of ongoing operations could be dangerous. The requirement to be accompanied by a military aircraft is also inaccurate, as civilian aircraft can operate in an MOA without military escort. Hence, the correct procedure is to verify the operational status of the area prior to entry.
