[0023] The safety-critical software referred to in this plan includes hazardous software (referring to software that directly causes harm or is used to control harm) and software that has an impact on hazardous software. The proposed health management method is applicable to the following types of safety-critical software :
[0024] a. Software used to control or monitor hazardous hardware and software. Such software generally resides in real-time embedded systems, such as cabin door control software, operating system or switch monitoring software.
[0025] b. Software that provides information for safety-related decisions. If the pilot must shut down the engine when the engine is on fire, the software that reads the discrete amount of engine fire and displays it to the pilot must be safety-critical software. Further, related software in all information processing processes, including sensor acquisition software, digital-to-analog conversion software, Display software, etc. ...
