These measures also aim to prevent cost escalation as well as deal with the increasing scarcity of radio frequencies. It is in this context that a new technology called Controller Pilot Data Link Communication(CPDLC) emerges, which aims to replace voice communications between pilots and air traffic controllers with a text messaging service for non-critical situations, applicable to aircrafts above a certain altitude. My project aimed at augmenting an existing simulator for air traffic control, called SIMATM, to support this new CPDLC functionality. The execution of this project followed the V-model of software development that has been adopted by NAV Portugal, E.P.E. The main deliverables are, on the one hand, a new Data Link Server simulator, or SIMDLS, whose development was decided during the problem analysis phase, and, on the other hand, the evolution of the internal components of the SIMATM simulator so that it supports CPDLC. Another deliverable of this project is the publication of a scientific paper in the 6th Iberian Conference on Information Systems and Technologies.porCommunicationData LinkSimulatorCPDLCAir Traffic Managementmaster thesis
