Controller pilot data link communications (CPDLC): os benefícios de sua utilização no espaço aéreo brasileiro

Abstract

The Controller Pilot Data Link Communication (CPDLC), as a new aviation communication system and for being in implementation process, is a little known among aviators in Brazil. It is about datalink communication that improves the information transmission between pilots and controllers. In this way, this research aims to verify the viability of using the CPDLC in Brazil as an additional tool for the air traffic service. In order to reach the proposed objective, a qualitative approach methodology, a basic research and a descriptive objective were adopted, through bibliographic and documental procedures about the theme. From the adopted method, it was possible to verify, among other verifications, that Brazilian airspace has a great horizontal extension, starting from the continent, and expanding until the 10°W meridian, in maritime space. This continental and maritime dimension is challenging for radio communications, which can present distinct kinds of problems, such as noise, difficulty in understanding the message, loss of signal. The challenging scenario also extends to delays in operations due to congestion in regions with higher traffic. A solution to such problems may be associated with the use of tools capable of improving message transmissions between aviators and flight control. In this sense, the introduction of CPDLC in this scenario helps aeronautical voice and reduces the inherent risks to communication, the reasons why it has already started to be implemented in Brazil. The research verified that the system activation has already occurred in the Flight Information Regions (FIR) of Recife and the Amazon, and currently the theoretical coverage of the Datalink system already covers almost 100% of the Brazilian territory, totaling 53 sites of implanted stations, to that soon the system will be operational throughout the country. With this, it is concluded that there is a future possibility for communication via Data Link to be used throughout Brazil, which will facilitate the understanding between controllers and pilots, especially for foreign crews, considering that messages are all via text. As a suggestion for future research, it is proposed to verify the use of the CPDLC across the country by commercial and executive aircraft, and to point out the differences before and after activating the system
