# Cloud Computing in Free Route Airspace Research
###### Abstract  
We use technical documentation, data structures, data, and algorithms in our research. These objects support our work, but we cannot offer a unique citation for each object. This paper proposes a method (for citation and reference management) to cite such supportive resources using Cloud Computing. According to the method, the publication cites only one source in the Cloud, and this source contains the Cloud schema, which describes the Cloud infrastructure. When we make a citation using the Cloud schema, we can pinpoint a cited object exactly. The proposed method supports open research; all research--Cloud items--is freely available. To illustrate the method, we applied it in the case of free route airspace (FRA) modelling. FRA is a new concept of Air Traffic Management and it is also the subject of our research.

a monitoring system to protect isolated and at-risk populations from the spread of viral diseases. The sensors are used to write data to the Cloud via the internet. Data evaluation will be the next part of the project. The common point between the free route airspace (FRA) and the monitoring system are the significant points. These points describe the areas of investigation or the location of the sensors. All Cloud applications are difficult to list; some applications can be found in publications [1; 2; 3]. These works deal with Cloud applications for software solutions [3], for scientometry and scientific literature [1], and for the application of technology in companies of various sizes [2]. The reason that we chose to use Cloud Computing and apply it in our research citations is because of the many benefits. It allowed us to create a virtual data repository to give us the flexibility of connecting to our documentation anywhere and at any time. This virtual data repository also reduces the effort required for citations (instead of citing multiple sources, we can use one Cloud reference). With the increasing number of web-enabled devices used in today's business environment (e.g., smartphones, tablets), accessing our data is much easier. Our Cloud Computing method can be used as a scientific publication reference management and resource management for any research area that does not rely on sensitive data. We use the Free Route Airspace (FRA), FRA mathematical modelling objects, and data structures together with the algorithms and the related documentation to demonstrate our method. A simple application of our research is shown in Figure 1.  
Research-related publications can cite only one object--the FRA Research Cloud [4]. At the same time, this Cloud can be used to manage research resources. The diagram was created based on the publication [5] as an insight into Cloud applications from a research perspective. _Brief Introduction to Free Route Airspace (FRA)_  
FRA is one of the key Air Traffic Management (ATM) functionalities to be implemented as part of the European Air Traffic Management Master Plan. The other ATM functionalities are described and available in the work [6]. FRA is a new concept of operations created to modernize the airspace and contribute to the reduction of ATM costs, of air transport's impact on the environment, fuel consumption, production of emissions, and, last but not least, it improves the efficiency of flights. FRA is defined as a specified volume of airspace in which the airspace users can freely plan a route by using the FRA Significant Points [4], Documentation Section). FRA Significant Points are specific points described (using the
