Abstract

The software of the onboard equipment complex of a civil airliner operates under the control of a real-time operating system (RTOS), part of which is a graphic component that generates the image of the pilot's display. This display indicates integrated information about the surrounding environment and the state of the aircraft's systems, transmitted from various applications. This paper provides the efficient and secure algorithm for generation of images from multiple applications running in different RTOS partitions onto a single screen. An approach using multi-layer visualization, which improves efficiency with hardware support for Video Object Plane (VOP) technology, is considered. This approach required the development of algorithms that comply with the ARINC 661 aviation standard and enable application execution in independent partitions. Meeting these requirements will allow the developed programs and libraries to be certified for use onboard civil airliners. An acceptable rendering speed of 25 frames per second was achieved, creating image layers in five partitions.
