Airbus is both willing and able to support airlines by providing direct assistance in costing and operational matters. As it runs dedicated departments for maintenance cost (AI/SE-M2) and for operational performance (AI/ST F), coordinated projects can be launched with the objective of consulting with customers and establishing cost index policies adapted to specific airline settings (fleet composition, type of network, economics, route and ATC constraints).
To accomplish this, information should be exchanged to enable proper and precise evaluations to be made based on the best possible assumptions. As said earlier in this brochure, much progress could be achieved by having airline accountants involved.
In practice, however, it has been hard for flight operation departments and airline financial analysts to come to synergistic teamwork in this matter. Some airline managements convinced of the potential of airline econometrics - have nonetheless succeeded in coming to grips with the cost index much to the success of their operating economics, let alone their balance sheets.
