In this paper, aircraft air distribution system has been analyzed. To achieve that, ducting pressure loss and air flow throw gaspers calculations has been done for cabin ducts in according to exact location of individual air distribution system in the cabin. Then the length of gasper air flow was compared with the distance between gasper outlet and passengers seats. Finally the results show good agreement between air flow throw gaspers and gasper to passenger distance that make comfortable air feeling conditions. Therefore adding of gasper system to available distribution system must be designed in according to least modifications, suitable location and good air flow throw gaspers.
