What is a FENCE check when entering and exiting the MOA?

A FENCE check is specifically conducted when entering and exiting a Military Operations Area (MOA) to ensure that all necessary protocols and procedures are followed for safe operations. The term "FENCE" is an acronym that stands for several critical safety and operational checks that include confirming communication frequencies, verifying aircraft status, and ensuring that weapons systems are configured appropriately. By performing this check, pilots can ensure they are prepared for any potential scenarios that could occur in the MOA, thus enhancing safety and operational readiness.

This practice is vital, particularly in areas where military training or operations are taking place, as it ensures pilots are not only aware of their own aircraft's status but also the communications and procedural aspects necessary to operate safely in a potentially high-risk environment. The other options involve important safety considerations but do not specifically define the FENCE check related to MOAs.
