I don't understand the concern.
I would think that looking at what's in the aircraft logs should reflect what the hours on the aircraft are unless your concerned that they also might be corrupted.
Here's my concern. I bought my plane flying. I was told it had "x" amount of hours which I confirmed on the page with the tach. From the comments, it seems you can adjust this? I was unaware of the "flight hour meter" and I stumbled across this a few weeks later after buying the plane. My concern is that the flight hour meter reads significantly more time than the tach...
I was about to call Dynon when this thread popped up to see why I have two different readings.
The tach should be reading less than other meters.. the tach only reads actual hours at full (max rated) rpm. So at reduced RPMs, it’ll real slower than a “Hobbs” meter.
Amazing, I've flown with the D180 now for 14 years and have never seen that FLTHRS!!!! There's prob other stuff on there I've also never seen, but I have seen the Total and Hobbs Hrs and yes both are resetable.
