Kuklev E.A., Professor, Doctor of Technical Sciences, was born in 1934; and graduated from the Kazan Aviation Institute (majoring in "aircraft construction"). He is an Honored Worker of the Higher School of Russia, Laureate of the commemorative medal of the Vietnamese People's Republic (2018) for his services in the preparation of scientific aviation personnel (candidates of Technical Sciences) and for the implementation of scientific and technical projects for civil aviation in Vietnam, Head of the Mechanics department of St. Petersburg State University, and Director of the Center for Expertise and Scientific Support of Projects in St. Petersburg State University. Earlier, he was the vice-rector for research in St. Petersburg State University of Civil Aviation. He is the author of more than 300 scientific papers and inventions in the aviation field, including those for development of air transport standards, with activity management standards for transportation of goods on the external load suspension of helicopters in the interaction of helicopter groups based on ICAO requirements.

Shapkin V.S., Professor, Doctor of Technical Sciences, graduated from Moscow Institute of Civil Aviation Engineers (1984). He is a Laureate of the Russian Federation Government Prize in Science and Technology, an Honored Transport Worker of the Russian Federation, and Director General of FSUE State Research Institute of Civil Aviation (FSUE GosNII GA). He is also an Expert of the Federal Air Transport Agency, Federal Service on supervision in the sphere of transport of the Russian Ministry of Transport, and the Interstate Aviation Committee. His area of specialisation includes air transport and aircraft strength. He is also the author of more than 200 scientific works.

Filippov V.L., Acting General Director of FSUE State Research Institute of Civil Aviation, Actual State Councillor of Russian Federation, graduated from Syzran Air Force Aviation School, Gagarin Air Force Academy. He is a specialist in aeronautical activity and a Class 1 military pilot.

Shatrakov Y.G., Professor, Doctor of Technical Sciences, Honored Science Worker of Russia, RATS full member, graduated from Leningrad Institute of Aviation Instrumentation and Leningrad University (Physics and Mathematics Faculty). He defended his thesis in 1966. He published more 400 monographs and textbooks on radio navigation, radiolocation, production organization. He prepared more than 100 candidates and doctors of science as a scientific adviser and scientific consultant. Scientific directions founded under the guidance of Y.G. Shatrakov are as follows: relative radio navigation; increased noise immunity of angle measuring systems due to suppression of correlation errors and interference; secondary radiolocation by individual numbers; reduction of labor intensity in the production of radio electronic products due to the introduction of flexible automated productions. He is the author including 30 patents for inventions in the field of radio technical systems; scientific supervisor of international projects for the creation of the MLS with Thomson-CSF (1980-1988), with US enterprises for the creation of joint LRNSs (long-range radio technical navigation systems) (Tropic-Loran) (1984), chief designer of on-board antenna-feed systems; founder of the correlation interference theory in aviation radio technical complexes and systems.
