How many ECS crews are required to maintain certification?

The requirement for two crews to maintain certification is based on the need for operational readiness and continuity in training. Having two crews allows for a balanced distribution of training duties, where one crew can conduct operations while the other crew is either training or resting. This not only ensures that at least one crew is always prepared to engage in tasks but also allows for ongoing skill enhancement and assessment of performance.

Furthermore, maintaining two crews fosters a collaborative environment where members can exchange insights and strategies, thus enhancing overall team competency. This structure also helps in meeting the needs for certification assessments and evaluations, as there will consistently be personnel available who are up-to-date with the proficiency standards required for certification.
