What is a key requirement for passengers on extended overwater operations?

The key requirement for passengers on extended overwater operations is that each must have a life preserver with a locator light. This regulation is essential for safety in the event of an emergency over water, where swift recovery and visibility are critical. Personal flotation devices equipped with locator lights enhance the chances of survival and rescue by improving visibility in dark or challenging conditions.

In extended overwater flights, having a life preserver with a locator light addresses both the need for flotation and the ability to signal for help if a passenger ends up in the water. The locator light increases the likelihood that search and rescue teams can locate individuals quickly, thus significantly reducing the risks associated with ditching into the ocean.

While other options touch upon important safety measures for passengers, they do not align with the specific regulatory requirements that prioritize survival and recovery in emergencies over water.
