What is a key characteristic of Military Operations Areas (MOA)?

A key characteristic of Military Operations Areas (MOAs) is that they are not restricted for entry, meaning that civilian aircraft can transit through these areas without needing prior permission, although it is advisable for pilots to exercise caution and maintain situational awareness when flying in or near them. MOAs are established to allow the military to conduct training and operations often involving high-speed maneuvers or other activities that may not be compatible with the presence of civilian traffic.

While it is beneficial for pilots to listen to any relevant air traffic control advisories or NOTAMs regarding MOAs, the operations within these areas will not inherently restrict civilian access. This differs from restricted areas that are explicitly designed to prohibit entry without authorization.
