Synthetic vision systems (SVS) are studied for some time to improve pilot's situational awareness and lower their workload. Early systems just displayed a virtual outside view of terrain, obstacles or airport elements as it could also be perceived through the cockpit windows in absence of haze, fog or any other factors impairing visibility. Required digital terrain, obstacle and airport databases have been developed and standardized by Jeppesen as part of the NASA Aviation Safety Program. Newer SVS displays also introduced different kinds of flight guidance symbology to help pilots to improve the overall flight precision. The method studied in this paper is to display navigation procedures in the form of guidance channels. First releases of the described system used static channels, generated once at the startup at the system or even offline. While this approach is very resource friendly for the avionics hardware, it does not consider the users, which want the system to respond to the current flight conditions dynamically. Therefore, a new application has been developed which generates both the general channel trajectory as well as the channel depiction in a fully dynamic way while the pilot flies a navigation procedure.
