"The objective of FRARS-2 (Future Regional Aircraft Requirements Survey – Part 2) is to conduct a survey of airlines’ high-level requirements for future regional aircraft, with specific focus on North American and African operators. This new survey is the continuation of a study conducted under the first Clean Sky Call for Proposals (Future Green Regional Aircraft requirements).In addition to an extended geographical coverage, the present study will bring innovative multi-criteria decision-making support methodologies and tools in order to translate the opinions expressed by the airlines' executives into concrete technology options for the Clean Sky GRA ITD.The proposed consortium (ENVISA & SustainAvia) has a long-time expertise in the fields of airline surveys and multi-criteria / interdependence models. Both companies have successfully cooperated on a joint survey of worldwide air operators and regulators under Clean Sky SGO ITD's CARING project. Furthermore, the consortium has multiple contacts with high executives of operators in both regions of interest for the present study - North America and Africa."
