AIRAC Cycle Discrepancy

Navdata Center shows the latest AIRAC as “Cycle 2106 rev.4” while FMS Data Mgr shows that the latest is “2106 rev 2”. Why are they not in sync? How can I get Little Navmap to rev 4?


the revisions are per dataset and not as a general number. In this case, we have updated the MSFS database because we have improved the ILS courses. In Little NavMap we haven’t change anything therefore no revision change.

So, all is good and correct so far
