Which NAV channel preset corresponds to MEI?

The correct choice indicates that Channel 7 is the designated NAV channel preset for MEI (Maritime Emergency Intercom). This means that when operators or personnel need to communicate specifically for MEI purposes, they would use Channel 7 as the predefined frequency.

Understanding the function and purpose of different NAV channels is crucial in maritime operations, especially for emergency communications. This preset helps streamline the process, allowing for quick access to essential communication without needing to manually tune the radio.

While the other channels are associated with different functions or may be designated for other types of communications, Channel 7's specific alignment with MEI showcases its importance in ensuring that safety-related communications can be efficiently executed in emergency situations.
