Passenger evaluation of the optimum balance between fresh air supply and humidity from 7-h exposures in a simulated aircraft cabin

For that study a full-scale model of an aircraft cabin section inside a climate chamber has been investigated. A powerful experimental facility was provided for the exploration of issues associated with the cabin environment and the comfort of passengers and crew. A wide range of parameters and equipment have been explored. The investigations have shown that increasing aircraft cabin humidity by decreasing the ventilation flow rate of fresh outside air would not reduce SBS symptoms typical of the cabin environment.
