"Project CARING (Contribution of Airlines for the Reduction of Industry Nuisances and Gases) aims at better understanding how airlines deal with the environmental constraints, currently and in the future. CARING pursues three main objectives in line with Clean Sky’s Systems for Green Operations ITD: - Gather trajectory data from actual flights. These trajectory data will be used in Clean Sky’s simulator to evaluate their environmental impact and will be compared with future optimal trajectories permitted by the progress of the Clean Sky programme. - Understand the current and future environmental constraints and the basis for taxations, emission permits, etc. - Model how airlines deal with the environmental constraints, and how it affects their economics, their operations and their strategy. To be comprehensive, the CARING study covers several models of airlines: regional, low-cost, charter and long-haul. For trajectory data, environmental specialists will work with airlines to record FDR data on a variety of routes (congested airports, secondary airports, medium haul, long haul), aircrafts (turboprops, single aisles, long range) and approaches (regular, CDA) that are relevant for an environmental study. Trajectory data will then be analyzed and synthesized for use within the Clean Sky simulator. For environmental constraints, the consortium will conduct a survey of existing and potential future international rules. At last, an economic modelling will be developed based on the previous surveys and an analysis of the other costs within an airline (crew, delays, missed connections, etc.). This economic business model will help understand how the environmental constraints might affect future airline strategies, fleet and network decisions. The consortium involves 9 airlines as well as airline environmental specialists, airline operations & costs specialists and air transport economists."
