In a passenger brief over water, what specific information must be provided?

In a passenger brief over water, it is essential to provide information about the use and location of life jackets due to the critical safety considerations in such environments. Overwater flights pose unique risks, and should an emergency situation arise, passengers need to know how to access their life jackets quickly and understand how to use them correctly.

Life jackets are vital for survival in the event of an emergency landing on water, where other resources might not be available. Providing clear instructions on both where the life jackets are located and how to use them reinforces passenger preparedness and safety, allowing individuals to act promptly during a crisis.

While other types of information—such as the location of restrooms, the duration of the flight, and the possibility of turbulence—are useful for passenger comfort, they do not directly impact survival during an emergency over water. Therefore, emphasizing the use and location of life jackets is of utmost importance in this specific scenario.
