We here propose an open science alliance for ATM, advocating for open data in such a framework. The benefits of adopting an open science approach are to be found, inter alia, through the independent verification and validation of reported impacts/results and achieved performance levels, i.e., through reproducibility. We consider that this can only be achieved through: (1) open access to scientific methods and data utilised; (2) open access to (analytical) code and methods; (3) open review of reported analyses/research. The proper application of such practices will reduce the innovation cycles in ATM, which is much needed by industry and society. Steps for forming an open science alliance for ATM are described. We propose further initial, specific recommendations for supporting open data and improved access for research
