What precaution should be taken regarding flotation equipment deployment system hatches before the aircraft comes to rest?

The correct answer focuses on the importance of ensuring that life rafts are not lost during the deployment of the flotation equipment. Before the aircraft comes to rest on water, it is essential to verify that flotation equipment deployment system hatches are functional and properly secured. If these hatches are not managed correctly, there is a significant risk that the life rafts could be prematurely released or damaged, rendering them unusable.

This precaution is critical because, in an emergency water landing, survival heavily depends on having accessible and operational flotation devices. Ensuring the hatches function appropriately and remain intact allows for the successful deployment of life rafts when required, significantly enhancing the chances of survival for the crew and passengers.
