The instrument panels of modern aircraft are created according to the concept of a "glass cockpit". This new interface concept enhances the perception of critical flight information by integrating it into one multi-functional display that provides a cohesive, easy-to-read view of flight information. The paper deals with the problems that arise in the development of a certified visualization system for the pilot's display, designed to work on civil aircraft under the Russian real-time operating system JetOS. It is shown that we have successfully solved the problems of multi-window visualization of many aviation applications with an acceptable speed on a promising aviation computing platform. The article lists several algorithmic solutions that allow achieving the required rendering speed, as well as outlines ways for further work.
