How many oxygen masks are located at the Cabin Observer Jumpseat?

The correct number of oxygen masks located at the Cabin Observer Jumpseat is two. This detail is important because the Cabin Observer Jumpseat is designed to provide both the observer and a passenger or crewmember assistance in an emergency scenario. Having two oxygen masks ensures that both individuals can receive necessary supplemental oxygen simultaneously in case of cabin depressurization or other situations that require the use of oxygen masks. This setup promotes safety and preparedness onboard the aircraft, allowing for a prompt response to emergencies. Understanding the specific safety equipment available at different jumpseats is essential for crew members, as it impacts their ability to assist passengers and manage in-flight emergencies effectively.
