Aircraft oxygen systems are designed to provide supplemental oxygen to pilots, crew, and passengers when flying at high altitudes where the air pressure and oxygen levels are too low for normal breathing. These systems are crucial for maintaining safety and preventing hypoxia (oxygen deprivation).

Types of Aircraft Oxygen Systems

1. Gaseous Oxygen Systems

   • Uses compressed oxygen stored in high-pressure cylinders.
   • Distributed through a network of regulators and masks.
   • Common in military and commercial aircraft.

2. Liquid Oxygen (LOX) Systems

   • Stores oxygen in liquid form at extremely low temperatures.
   • Converts liquid oxygen to gas before distribution.
   • More efficient for military and high-performance aircraft.

3. Chemical Oxygen Generators

   • Found in commercial airliners for emergency use (passenger oxygen masks).
   • Activated by pulling a mask, triggering a chemical reaction that produces oxygen.

4. On-Board Oxygen Generation Systems (OBOGS)

   • Used in modern fighter jets and military aircraft.
   • Extracts oxygen from engine bleed air, eliminating the need for stored oxygen tanks.

Key Components of Aircraft Oxygen Systems

• Oxygen Cylinders/Tanks – Store oxygen in gaseous or liquid form.
• Regulators – Control oxygen flow based on altitude and demand.
• Masks & Cannulas – Deliver oxygen to the user (full-face masks, nasal cannulas, etc.).
• Emergency Oxygen Systems – Backup supply for decompression events.
• Valves & Piping – Transport oxygen throughout the aircraft.

Maintenance & Safety Considerations

• Regular inspection and leak checks to prevent system failures.
• Ensuring oxygen purity and avoiding contamination (oil/grease can cause fires).
• Proper handling and storage of oxygen tanks under high pressure.
• Routine functional tests of regulators and distribution lines.
