Hi, i am looking at an Acclaim that has a large gap in time between the tach time displayed on the G1000 and Hobbs meter at the back. The Hobbs shows around 930 hours while the tach time is at 1400. How can this happen? Is this a serious concern? Also, the airbag seatbelt expired. Would this affect the airworthiness? thank you, yariv

I see TT as a higher number than Tach but lower than Hobbs. Reading up about this, it seems this is less definitive than I thought. What should the TSMOH hours be based on? Thx.
I thought the Hobbs meter in my M20J was running slow. If I were to start my engine and then shut it down an hour and a half later, I thought the Hobbs should read 1.5 hours more at engine shut down than it did at start up. But this doesn't seem to be the case, it seems to indicate more like 1.2 hours or so. All the planes in which I trained (152's, 172's, Archers) had Hobbs meters which seemed to indicate clock time from the time the master was turned on (or maybe oil pressure not at zero) until shut down. My mechanic said in Mooneys, it's a little more complicated. Does anyone have a
