Abstract

Leaks developed in an aircraft cabin, if not detected early, can cause depressurization and can consequently lead to conditions such as decreasing cabin air quality, passenger hypoxia etc. Hence, it is required to identify and continuously monitor slowly developing as well as rapidly developed fuselage leaks. This paper provides a method for detecting cabin air leakages by monitoring the extent of opening or closing of cabin air pressure control system outflow valves.
