What is the total number of POBs that should be present on the aircraft?

The correct total number of Portable Oxygen Bottles (POBs) that should be present on a Southwest Airlines aircraft is four. This is important because POBs are a critical safety feature used to provide emergency oxygen to passengers and crew in the event of cabin depressurization or other emergencies.

Each aircraft in the Southwest Airlines fleet is equipped with a specific number of POBs to ensure that there is enough oxygen available for both crew members and passengers, complying with regulatory safety requirements. Having four POBs allows for sufficient coverage throughout the cabin, ensuring that all areas can effectively respond to an emergency, and helps comply with operational guidelines related to safety equipment availability.

Understanding the need for portable oxygen systems is essential for flight attendants as they play a key role in ensuring passenger safety and well-being during flights. Being aware of the equipment available onboard, including the number of POBs, is part of preparing for any potential emergencies.
