The Direct Operating Costs (DOC) are directly influenced by the parameters and the aircraft's performance and are commonly used for aircraft evaluation. Therefore, a simplified method for DOC estimation, based on „From Aircraft Performance to Aircraft Assessment“ by J. Thorbeck <sup>[1]</sup>, is provided. The DOC are determined for one year and the entire depreciation period.
In many ways, this method reflects a European cost scenario, for example in terms of assumptions on annual utilization, night curfews, but also with regard to personnel costs and fees incurred. The price factors used are therefore stated in EUR. However, as the aviation market is a dollar market, the cost shares are converted into US dollars using an exchange rate of EUR $e$ (user input).
