There was a great interest in the transnational AirTN Call 01/2012 from industry, research establishment, and academics. It has been closed for submissions on 24 September. The AirTN Board, including the involved countries Austria, Ireland, Spain, and Sweden, is delighted with the result of the call in terms of the volume of submitted proposals. The proposals will now be evaluated. In parallel, AirTN will evaluate the submission phase of this call to learn for future transnational calls.
