Nav data out of date after installing latest airac cycle

I’ve installed the latest airac cycle with the FMC Data manager to my custom data folder in X-plane 11 (Airac 2101). It doesn’t look like the airac 2102 is available. And on the FMC is says that 2101 airac is active. And the date-time in the plane is set to track real-world date and time and it still says nav data out of date. What can I do to get the message to go away?


Hi Theo,


AIRAC 2101 is current. AIRAC 2102 becomes effective 25 FEB 21.

Please see AIRAC Cycles .


Hi Ian,

Although my FSLABS FMGC is showing NAV2101001 is active, the period indicated is 31 December to 27 January. How is this possible?

An issue with the FSL itself fixed for the next update.
