Is this normal behavior for Navio+/ArduCopter/Mission Planner?

I’ve nearly finished upgrading my hex with a Navio+ FC. I’m not having any particular issues and all motor tests pass as I go through in MP. However, I notice every action causes “APM initialsing…” to show up in the HUD. It does it before arming and (I think) when disarming. I don’t notice any obvious issue with it but wanted to see if this is normal behavior before a test flight. I’ve never noticed that behavior with an APM 2.6 FC.

I am going to maiden this Navio build tonight. I don’t see any reason that makes me think this behavior is fatal but I’ll report back to the thread either way.
