Concorde - Constant Oscillation in INS Mode
-
Hi,
Summary: When using INS mode for lateral navigation, the Concorde constantly oscillates around the enroute leg. This phenomenon is even more exaggerated at high speeds.
How to reproduce:
- Boot up a flight
- Accelerate to supersonic
- This behavior occurs after overshooting turns
Here's an example of the "oscillation" that occurred during my last flight:
Thoughts: An uneducated guess from what I vaguely remember in my college control theory class, it appears the parameter to the LNAV PID controller is badly tuned.
Please look into this, much appreciated!

@ewky Just seen this. Are you using Airways? Concorde is much too fast for any other form of INS navigation. I have not seen oscillations unless the waypoints are just too close together, in which case Concorde cannot track them accurately at Mach 2
