With flying being one of the most popular travel methods, the considerations and regulations regarding safety have become increasingly important. Before passengers step foot on an aircraft, manufacturers pay significant attention to the intricacies of air travel. To survive high altitudes and low atmospheric pressure, a pressurization system is put on all aircraft to assist passenger breathing. These pressurization systems constantly pump fresh, outside air into the airplane body allowing for safe and convenient air travel. Having a reliable pressurization system is crucial to the safety of the pilots and passengers on board, but what happens when pressure is compromised? Having reliable backup air is critical to the performance of the pilots, and safety of the passengers.
