With the increase in passenger’s traffic across globe, the global demand of aircrafts manufacturing and distribution should be assured as per regional requirement. Regional predictions in terms of passengers’ movement, aircraft demand, etc., have been made e.g. continent have individual prediction of increase in passengers’ traffic. With these forecasted increase in passengers’ traffic, we illustrate requirement of types of aircrafts as per geographical regions. Different size of aircrafts is taken into account and is compared with increase in passengers’ traffic. With this increasing demand, planning in aircraft manufacturing industries is necessary, considering situations like, limited airside capacity, airline companies’ demands, etc., planning in manufacturing of aircrafts is extremely essential in terms of maintaining the ratio of demand, requirement, replacement and decommission of aircrafts with respect to manufacturing speed and supply. Taking perception of aircraft manufacturers, we will analyse the factors on which the aircraft manufacturing relies on.
