After having a preliminary study including job and population analysis, the development process starts with determining the training objectives. In accordance with the provisions of Regulation No 805/2011 laying down rules for ATCO licences the initial training shall ensure that student air traffic controllers satisfy at least the objectives for basic and rating training, as described in Eurocontrol’s ‘Specification for the ATCO Common Core Content (CCC) Initial Training’, edition 1 of 21 October 2008. The CCC objectives were originally developed after the major ATCO job disciplines had been task-analysed and, therefore, this aspect is not included in this article. Nonetheless, any local or future ATCO training development may need to consider repeating the whole process in order to include new, modified or updated tasks (objectives).
