An airspace model aplicable for automatic flight route planning inside free route airspace

The article is strongly related to the Single Europ ean Sky ATM Research (SESAR) project. The project’s objective is the improvement of air transport above Europe 0. Since Air Traffic Management (ATM) is involved to o btain more effective approach to air traffic flow managing activities, the concep t of Flexible Use Airspace (FUA) has arisen in result. ATM is a quite developed avia tion’s subdomain, therefore currently existing airspace state has been described b ri fly in the article, referring to the presented solution concept. The notion of Free Route Airspace (FRA) airspace model defined in this article relies on mathematica l description. The selected approach clarifies airspace as a set of squares or cubes that have volumes with appointed values due to certain conditions in the c onsidered time (i.e. traffic flow or weather). The model has to ensure facilitation o f flight route planning and warrant aircrafts separation towards flight safety assuranc e. The concept assumes that this airspace model will provide assistance for airspace user to select essential flight plan criteria, such as economy, time, etc. The path will be appointed according to personal preferences, based on the model from which fu rt er elaborated algorithm will evaluate situation. The presented solution is a response to air traffic growth. Therefore it supports the SESAR project through research and development activ ities. The description proves that airspace model would create enhancement in fli ght planning for airspace users.
