How many total night hours are required per currency maintenance cycle?

The requirement for a total of 10 hours of night hours per currency maintenance cycle is grounded in ensuring that officers maintain the necessary proficiency and familiarity with operating under low visibility conditions. This is crucial for safety and operational readiness, as night operations present different challenges compared to daytime activities.

The 10-hour threshold is established as sufficient time for personnel to practice essential skills such as navigation, communication, and decision-making in darkness. This experience helps in reinforcing situational awareness, response to emergencies, and the ability to apply navigation techniques without the benefit of ambient light.

Maintaining this currency is vital for operational effectiveness and safety, especially for missions that may occur at night or in low-light conditions, where the risks and complexities of navigation and vessel handling are amplified.
