Study of the possibility of im-proving the efficiency of updating aeronautical data of AIRBUS A310 flight control system

Due to the constant tightening of flight safety requirements in the country and abroad, with the constant growth of air traffic, more and more requirements are imposed on the reliability, non-failure operation of air navigation systems and methods for updating their air navigation databases. Besides, there arises the problem of the relevance of the databases used in accordance with the AIRAC cycle, since the risk of emer-gency situations or disasters increases in the case of using non-updated aeronautical information in the flight management system (FMS), flight management computer system (FMCS), satellite navigation system (SNS), ground proximity warning system (GPWS). The paper proposes to consider the issues of improving aircraft navigation systems and updating databases using FMS-type computing systems. Russian aircraft use FMCS-95-1V, onboard ground proximity early warning systems (GPWS) and onboard satellite naviga-tion systems operating with an orbital satellite constellation (GPS, Glonass). All of them are equipped with aeronautical databases, which, in accordance with the AIRAC cycle, are updated on the ground by engi-neering and technical personnel every 28 days. The frequency of updating depends on the receipt of chang-es in navigation data for the operation of these systems. The paper considers the issues of operational characteristics analysis, methods of data transmission to onboard aircraft systems, development of an aer-onautical data transmission system, development of a remote transmission control system, as well as the development of data transmission algorithms, theoretical and experimental justification of the choice of a transmission system model. The use of the considered complex leads to a qualitatively new level of efficien-cy, reliability of updating air navigation databases in the FMS, SNS, GPWS, FMCS, which will affect the increase in flight safety, as well as the regularity of flights in the absence of aircraft downtime according to the criterion of operational updating databases under the AIRAC cycle.
