MOAs are established to?

The establishment of Military Operations Areas (MOAs) is primarily intended to separate certain military activities from Instrument Flight Rules (IFR) traffic. This means that within an MOA, military training operations can occur without interference from civil aircraft operating under IFR, ensuring both the safety of the training missions and that of civilian pilots.

When military aircraft are conducting specific training that may include high-speed maneuvers or other potentially hazardous activities, the MOA provides a designated space where these operations can happen securely. This helps to maintain a clear distinction between military training activities and civilian aircraft operations, creating a more organized and safe airspace environment.

In this context, while prohibiting all civil aircraft is a potential outcome of some restricted areas, MOAs specifically allow for civilian aircraft to transit through when they are not active. Similarly, while some areas may restrict civil aircraft during high-density training, that is more related to Temporary Flight Restrictions, not the broader purpose of MOAs. Therefore, the primary function of MOAs is indeed to provide a structured environment for military activities while ensuring the safety of IFR operations.
