Evaluating airliner performance, Part 4

By Bjorn Fehrm Subscription required. Introduction Oct. 05 2015, ©. Leeham Co: In the final part of our series about comparing and evaluating economic and operational performance of airliners, we will combine the different Cash Operating Costs (COC) with the capital and insurance costs to form the Direct Operating Costs (DOC). We will also look at typical values for the different costs that make up the DOC for a single aisle Boeing 737 or Airbus A320 aircraft and a typical dual aisle Boeing 787 or Airbus A330neo aircraft. Summary:
  • We describe the cost that form an aircraft’s capital costs and how these differ between an ownership or a lease model.
  • When forming the Direct Operating Cost (DOC). The low fuel price of $1.50 per US Gallon has lowered the fuel’s part of DOC to around 20% for single aircraft and 30% for dual aisle aircraft on their typical mission types.
  • This means that other costs types in the DOC gets a more dominant role. We show which are the costs to look out for.
  • Finally we give the typical CASM (Cost per Available Seat Mile) values for single and dual aircraft in the market.
