Research on Coding Of Conventional Procedures Based Upon ARINC Specification 424

Most of the conventional procedures could be coded effectively into the navigation database based upon the ARINC specification 424. But in some special cases, it's hard to code as the procedure's designer does not comply with the ARINC specification 424 when they design the conventional procedures. This paper will analyze some of these special cases from the practical experience, and will also provide the solutions to these cases after the analysis.
