Oxygen systemsin unpressurized aircraft are generally of the "continuous flow" type.Oxygen systems in unpressurized aircraft are designed to provide supplemental oxygen to pilots and passengers at high altitudes where the air is thin and oxygen levels are lower. The two main types of oxygen systems used in aviation are "continuous flow" and "demand flow" systems.Continuous flow:In a continuous flow oxygen system, oxygen is continuously supplied to the user at a fixed flow rate, regardless of breathing patterns oraltitudechanges. The flow rate is typically adjustable and can be set based on the altitude and the user's oxygen requirements. Continuous flow systems are commonly used in unpressurized aircraft as they provide a constant and reliable supply of oxygen.Demand flow:In a demand flow oxygen system, oxygen is delivered to the user only when they inhale or take a breath. The system senses the user's breathing and releases oxygen in response to the demand. Demand flow systems are often used in pressurized aircraft where the cabin altitude is regulated and oxygen is only needed during specific conditions, such as high altitude or emergencies.Since unpressurized aircraft operate at altitudes where continuous oxygen supply is necessary, continuous flow oxygen systems are typically used to ensure a constant andsufficient supplyof oxygen to the occupants throughout the flight.learn more aboutOxygen systemsherebrainly.com/question/8831529#SPJ11...
