Sorry if there was any misunderstanding. What I mean is that, as far as I know, all aircraft are using the same source of ARINC 424 data which comes from Jeppesen and Navigraph(T data).
This could be reflected in Wrong procedure data in VHHX - #2 by NAVData . orry for my earlier mistake on those pages, For example, E RM can be recognized under the ARINC 424-23 specification, but not in ARINC 424-18. So, if an aircraft is using navigation data based on ARINC 424-18, this might lead to errors. Sorry for my earlier mistake on that point.
In summary, if some data does not comply with the ARINC specification that aircraft used, it might affect other related data as well. That’s why I opened this ticket.
Referring to your reply here, you mentioned that this line is considered as an IAF. However, according to the screenshot of the specification I provided, the last character A can only be used in APCH procedures, not in STARs.
Please let me know if I have misunderstood anything. I look forward to your clarification.
Thanks in advance!
