The 21st century has seen aerospace flights become possible, and in 2005 the ICAO adopted the Concept of Suborbital flights1 in order to organize them within the legal framework. The Concept governs the flights, including ones for commercial purposes, for the international suborbital transportation; however, no international legal standards have yet been adopted concerning this question. The paper analyzes the documents of the UN, ICAO, the Russian and foreign doctrines the content of which reflects the problems of organization of aerospace navigation within standards setting. The conclusion is made that in order to solve the organization questions associated with aerospace navigation it is the notion of "aerospace flight" that has to be defined first of all and its qualifying attributes have to be singled out. © 2018 Transilvanian Association for the Literarure and Culture of Romanian People (ASTRA).
