Software Management Module 5:13

Software Management - The title consists of  two words, software and management. The software can be defined as the program that are used by a computer. We can  basically divided software into 2 groups, operating software and application software. Operating software focus on making the computer and its accessories work. The application software is the program designed to produce the specific job for the user.
Management control is the process planning and other activities to ensure that the software meets the desired results. There more to the application of management, but I always stress on the management of the process, which relate to the software life-cycle.

  

Software Management is under the subtopic 13 in the Module 5 for the EASA part 66 license. Module 5 is about Digital Technique and electronic instruments. In teaching this module, I expect the students to be able to explain and give examples to show their understanding of the modules title.  It 

Software in a necessary components of an aircraft system. Examples of aircraft systems using software are...primary and secondary flight controls, engines controls, electrical generation and distribution, brakes and navigation systems.

Let us take a look at the life cycle of a software. The like of human life cycle, the software has the different phases of life. The authority is interest to monitor and control the quality of the different phases. 

The RTCA and Eurocae are responsible to come up with guidelines to ensure the the software used on the aircraft meets the required specification. The specification was published in the joint documents, DO -178/ED - 2. The current  version of the documents are given in another slides.
The Malaysian Civil Aviation recognized the document through its airworthiness directive AN57.

The document gives the outline for approval of software. The designed of the software must be done by an approved company. The requirements are described by RTCA  and Eurocae.
