As described in the title, the HSI and INS never agree on Distance and Time. HSI is set in INS mode and, as it can be seen, I don't have any active VOR tuned in. Is this a quirk of the real aircraft or a bug? In that case, which reading is the correct one? Also, the AP has never managed to track the INS properly in all the flights I've done, always a bit off-set, especially when the TO and FROM waypoints are close to each-other or in tight turns.
