How often must pilots complete their proficiency checks according to FOM regulations?

Pilots are required to complete their proficiency checks every six months according to FOM regulations. This requirement ensures that pilots maintain a high level of skill and knowledge necessary for safe flight operations. Regular proficiency checks help ensure that pilots are up to date with current procedures, regulations, and any technological advancements in aircraft systems. The six-month interval strikes a balance between allowing adequate time for pilots to practice and sharpen their skills while also ensuring that they are consistently evaluated within a reasonable frequency. This approach helps maintain safety and operational readiness in a dynamic aviation environment.
