Hello everyone, I have a small question on PMDG 777 Navdata Format. PMDG does not publish annotations on its navigation data. In the table “tbl_enroute_airways”， there is a row called “seqno”, its more likely to be a serial number, however, there is no regular pattern for it. How is it based on?
Hi,
It’s a part from the ARINC424 specifications. You can buy the specification from here.
In general, it is not allowed and also not supported nor recommended to change anything in the database. Further, it is also not allowed to use it for any other development and/or re-use it for any other project without our written permission.
Cheers
Richard
Hi again, thanks for your response. I saw the specifications in 5.12 part and I think that’s useless. I’m not a developer or something like that, I’m just curious about how it works, what’s the function of the seqno number.
Cheers,
Justin
