The Boeing 737 NG’s Nitrogen Generation System (NGS) is an intricate mechanism designed to enhance flight safety by reducing the risk of fuel tank fires. This system works by using hot bleed air from the aircraft’s left pneumatic manifold, processed to create nitrogen-enriched air for the center fuel tank, thereby lowering the risk of combustion.
The Boeing 777’s air conditioning and pneumatics system is designed for efficiency and ease of operation, with automated controls minimizing crew actions. The system automatically adapts to various flight conditions, including automatically removing pneumatic loads in case of an airplane stall. Advanced Built-In Test Equipment (BITE) monitors system components to the Line Replaceable Unit (LRU) …
The hydraulic system pressure in the A380 is increased to 5000 psi, allowing for a weight reduction of over 1000 kg due to smaller equipment and components. A key design feature is the placement of main hydraulic components in the pylons, optimizing Engine Driven Pumps (EDPs) function and eliminating high points between the reservoir and …
