Is the latest airac 0513 from Richard Stefan labeled "RC3" all right to use with RC4?Thanks.

Hi,As far as I know there's no need to do this since the fixes info is now read from the flightplans and not the RC database.Others will correct me if I'm wrong!All the best,John

i did a quick search of the code. i do not use the i4.csv file at all.i do use the n4.csv file, to find the frequency of each checkpoint. so i should probably update that.but then, what happens when the navdata is not in synch with fs? then i'm going to be giving you a frequency for a vor from the navdata, and fs is going to have a different frequency. jd

So I should not update RC4 with the 0513 airac data?

we've tested rc v4 and fs2004 with the data that is in there for 3 years. never had a misplace freq. i wouldn'tif there is a need to do it, i'll make the change, and when you "check for updates" then you will get the official file from usjd

Thanks, jd.Why do I get a "debug" file size warning message when I click on "update"?

in case there is a problem with the update, there will be a log that i can help you figure out the problem.the same dialog box comes up when you click the debug button.jd
