When is aircrew flight equipment training typically required to be refreshed for compliance?

Aircrew flight equipment training is typically required to be refreshed annually to ensure that all personnel are up to date with the latest procedures, safety protocols, and equipment usage relevant to their roles. This annual requirement helps maintain a high level of proficiency and familiarity with the equipment they may need to use in emergency situations. Regular training refreshes knowledge and skills that might diminish over time, ensuring that aircrew members can effectively respond in critical circumstances. Timely training ensures compliance with safety regulations and helps mitigate risks associated with flight operations.
