Aircraft Oxygen Systems

Oxygen Systems in Aircraft

• Oxygen is essential for life, especially above 10,000 feet where the air becomes thinner, and breathing unassisted becomes difficult.
• The aircraft's oxygen system becomes a critical safety component in high-altitude environments.

Types of Oxygen Systems

• Chemical oxygen generators for passengers
• Gaseous oxygen systems for the crew
• Each system is designed with specific roles in mind to ensure everyone onboard has access to sufficient oxygen levels.

Components of Oxygen Systems

• Oxygen masks and regulators
• Storage cylinders
• Intricate network of tubing
• Every piece plays a pivotal role in ensuring the system's functionality.

Servicing Requirements

• Regular inspections are paramount to prevent malfunctions.
• Maintenance checks include verifying leakages, assessing pressure levels, and ensuring the correct operation of flow regulators.
• Servicing is a regulatory requirement, and authorities like the FAA mandate rigorous servicing schedules.

Importance of Servicing

• Skipping routine maintenance can lead to system failures, which might result in inadequate oxygen supply during emergency situations.
• Proper and timely servicing is crucial for ensuring the safety and well-being of passengers and crew.

Safety Implications

• Inadequate oxygen supply during emergency situations can be catastrophic.
• Oxygen systems are a lifeline in the sky, providing necessary breathing air when cabin pressure drops or at high altitudes.

Proper Use of Oxygen Systems

• Pilots must use supplemental oxygen after 30 minutes of flying above 12,500 feet, and continuously when flying above 14,000 feet.
• Passengers require supplemental oxygen above 15,000 feet.
• The proper use of oxygen systems ensures that everyone onboard maintains an adequate level of oxygen saturation in their bloodstream to prevent hypoxia.

Steps for Servicing Oxygen Systems

• Inspection of oxygen cylinders for damage, corrosion, and current hydrostatic test date.
• Verification that pressure gauges are reading accurately and that regulators are functioning correctly.
• Replacement of oxygen as needed, using high-grade aviation oxygen to prevent contamination.
• Checking the oxygen masks, hoses, and connectors for cleanliness and signs of wear or damage.
• Ensuring that the system is correctly stowed and secure, with masks easily accessible in the event of an emergency.
