You can keep using the outdated database in the X-Plane 11, the FMS will be fully operational as is. It just gradually becomes out of sync with the real world data. For example, you’ll find the available SIDs and STARs in your FMS to be different from the current publications.
Yes, it can be a nuisance if you fly online using an out-of-date database. It’s much less of an issue if you just fly by yourself. You can always buy a one-time, one month, “subscription” (e.g. Navigraph) to get X-Plane’s database current, for under US$10.
There is an instruction file in the X-Plane\ Instructions folder: “X-Plane FMS Manual.pdf”. Follow its example and it walks you through the basics for programming the FMS from airport A to airport B.
Thank's for all help.
Hitting the “CLR” button should clear the message for you and allow further inputs, as I recall.
My AIRAC is currently up-to-date, so I really can’t verify that for you.
