That should be no problem as the autopilot in FG should be running at a fixed framrate (/sim/model-hz) these days. That is, fixed in simulated time, which is all that should matter. (As an aside our time management is still pretty messy and lots of things that ought to use simulated time seems to be using real time instead - try increasing the simulation rate and see how many virtual things that do not speed up...)

Why? It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense.
