Generation of Symbols on Primary Flight Display and Its Validation under Host Environment


The aim ofthis paper is to develop the symbols (graphical viewof flightindicators) of Primary FlightDisplay page atthe host environment and to validate the symbols using GUI (Graphical User Interface) at run time. The symbols of these indicators can be developed using OpenGL libraries which gives no compatibility problems at the target system (Helicopter). With the support of these libraries, the symbols for the indicators can be developed. In the host environment, the data required for the symbols of flight indicators can be given manually by the developer at the compile time or at the run time using GUI. Based on the given data, symbols can be displayed and the developer can check the correctness of the symbols. The process of giving data (periodic data) to the program at the compile time and at the run time can be compared with each other. The method of initialising the structures at the compile time increases the number of times the program being executed. So the GUI is developed with all the required controls which can receive all the valid and invalid constant values at run time. It reduces the number of executions of the program. Thus improves the validation efficiency. With the support of developed GUI, the program can be executed for one time the symbols on OpenGL window can be validated against all the valid and invalid values. Thus improves the efficiency of validating the correctness of symbols by the developer. This process can be applied in the development and validation of other pages of IADS (Integrated Architecture and Display System).
