"COOPERATEUS is a European Project within the Framework Programme 7 (Research / Aeronautics and Air Transport) aiming at establishing an initial framework, data base and network, in order to facilitate and enhance the cooperation in R&T activities between the two largest world players in aeronautics, i.e. the USA and Europe. It will introduce a more structured dialogue to identify the similarities in the respective research agendas / road maps. It will be used to create a better mutual understanding, thus permitting to Build up ad-hoc EU-US R&T cooperation areas of mutual benefit propose win-win R&T roadmaps / cooperations (ex: volcanic ashes) Have a mutual understanding of administrative mechanisms: clarify the principles governing such EU-US R&T cooperation, respective funding mechanisms, IPRs, …etc…and the main barriers to that cooperation and suggest ways to overcome all the problems.COOPERATEUS project will indicate the areas where the cooperation topics are mutually favored assuring a good reciprocity between the parties.More over, COOPERATEUS is in the logic of the EU-US memorandum of cooperation (MoC) presently under preparation.It will not interfere with the various EU-US R&T cooperative activities already undertaken, but might nonetheless provide rules and reference that could be beneficial to all.Finally the project will provide common R&T road maps for cooperation to be introduced in future calls for proposals within Framework programmes of the European Commission and mechanisms in the US."
