Navigation error after take of from roadbase

[Ramius007]

Using roadbase on Buddyspike server, despite entering runway heading manually (propably not very precise) few minutes after take of "nav sys" error appeared, but to my supprise I was able to switch betwean My 2 entered waypoints, heading and distanes looked correct as well, so question is, is it a bug, that Viggen can show nav sys error, even if nav sys is working correctly, or there was real navigation error, but too small to affect navigation, becouse diffrence betwean entered runway heading and real take of heading was too small?

If you have the log from the mission, you can upload it here and I'll have a look. It should say what happened.

Nope, seems not saving from this server

The log is what I want (and is always created), not a track or tacview. Should be in your DCS folder in saved games (dcs.log is the file name).

The navsystem will work. What most likely causing this is that runway heading is wrong.
