In this article the problem of designing of indication pictures in avionics with the use of SCADE integrated design environment is considered. The SCADE design environment includes such implemented tools as SCADE Suite, SCADE LifeCycle, SCADE System and SCADE Display with broad functional capabilities, which are to be used by the developers of the indication pictures for an automated code generation of the functional software, which ensures displaying of the navigation information on a liquid crystal panel of the onboard indication equipment. The authors propose a structural scheme of an automated workstation for the developers of the indication pictures. The workstation includes software components, technical and information support tools. The following results are offered: an algorithm for formation of a static indication frame with the use of SCADE Display and an algorithm for formation of a dynamic indication frame using SCADE Suite tool. The static indication frame is a picture with a set of "frozen" graphic primitives (lines, symbols, circles, etc.) placed within the field of a liquid-crystal display. The dynamic indication frame, i.e., the changing numeric values of the navigation parameters corresponding to the movement of the aircraft, displayed on a screen, is implemented by the tools of SCADE System software. In the SCADE System software components a user can have access to the virtual address space, in which it is necessary to specify the addresses of the physical i/o devices of the on-board indication equipment and also to set parameters of the communication protocol, which is supported by the subscribers within the avionic equipment. Specification of the addresses of i/o devices and parameters of protocols in SCADE Display and SCADE Suite components is necessary for establishment of a logical link between each displayed navigation parameter and its corresponding source within the onboard equipment, which generates the code of a physically measured value.
