Analysis of Aircraft Ground Power Cost Based on Different Power Supply Methods

Too aircraft hold on the ground not only brings inconvenience to passenger travel, but also increases the operation cost of airlines. Power supply equipment mainly includes APU (Auxiliary Power Unit) and 400Hz electrical power. According to aircraft ground operational situation, a mathematic model was established based on those different power supply methods. Taking Airbus319 for example, this paper utilize computer simulation quantify the proportion of energy consumption, the flight crew cost and other airlines concerned cost. The result shows, the aircraft ground staying cost may reduce by using ground electrical power supply compared with aircraft carry on APU. This model can be used to refine aircraft ground staying cost structure and quantify delay cost differences in different power supply models. The detail results of the analysis of the proportion of energy consumption accounting in the total cost provide proper cost suggestions for airlines, airports and passengers.
