On June 28, TCab Technology and AVIC Institute of Computing Technology jointly held a delivery ceremony for the E20 eVTOL avionics system display. The E20 eVTOL avionics display system uses domestically produced core hardware and operating systems, achieving comprehensive breakthroughs in performance, safety, and human-computer interaction, and has become a benchmark product in the domestic eVTOL avionics field. The system is equipped with domestically produced core processors and graphics accelerators, with computing power increased by 30% over similar products on the market; it uses the Tianmai operating system (ACoreOS), which provides strong real-time scheduling and memory protection mechanisms, and improves system reliability by more than 50%.
