  Blockchain technology, within its fast widespread and superiority
demonstrated by recent studies, can be also used as an informatic tool for
solving various aviation problems. Aviation electronics (avionics) systems
stand out as the application area of informatics methods in solving aviation
problems or providing different capabilities to aircrafts. Avionics systems are
electronic systems used in air and space vehicles for many purposes such as
surveillance, navigation and communication. In this study, the applicability of
blockchain technology as a new approach in the development of avionics systems
is discussed, and in this regard, a method inspired by the previously
implemented applications in electronic flight systems is proposed to help
evaluate the applicability of this technology in new avionics system designs.
The potential of blockchain for solving the problems especially in basic
services, communication, navigation and flight management systems; the problem
structures for which application of this technology would be a reliable
solution; and the superiority and inferiority of its use in avionic systems are
explained. A guiding paper is proposed for aviation engineers/experts to make a
decision on applying blockchain into avionics systems.
