“Proposal/Rationale for Flight Crew Alerting of Cyber Events That Affect Avionics Functions” was presented by Air Line Pilots Association, International (ALPA) in December 2019 in RTCA Special Committee 216, outlining concerns around aircraft cybersecurity2 from the pilot’s perspective. Since then, there have been updates in industry standards and regulations as well as more collaboration with other aviation ecosystem stakeholders. This paper outlines discussions starting in 2021 between pilots, represented by ALPA, and airplane and avionics system manufacturers, represented by the Aerospace Industries Association (AIA) Civil Aviation Cybersecurity Subcommittee. This paper summarizes topics which were covered in those discussions and the conclusions which were drawn. Many of the topics resulted in considerations for future research activities, design, and process updates contained within the document.
