Yes we do.
Yes we did it for a number of reasons. We like to be able to check the actual engine run time for the most part. The Hobbs is what we use to tell us when to change the engine oil. We have a Garmin G3X touch panel, but I find that the Hobbs meter is not affected or tide to anything in the PFD or panel. It is on a it's own individual power supply and regardless of anything it will tell us quicker and more reliably when the engine has oil pressure, so it is also an oil pressure gage back-up. If you have a good Hobbs, just look at the far right side of the readings and you will see a little black and white wheel. That wheel will start ticking and turning as soon as there is more that just a few pounds of pressure in the oil passages. I also use it to log my flight time, just like in the old trainers you flew. I wright the Hobbs time before engine start on my knee pad along with fuel levels and weight and then after engine shut-down I mark the time again. I know what the FAR's say, but this is an old and still accepted practice. I do look at the EFIS, Hobbs time and flight time every now and then, but they are more of a distraction than a need to thing. Sure I would do it the same in anything we own. Just the way we do ours. Hope this helps. Yours, R.E.A. III # 80888
P.S. It is on a kick panel down on the right side next to the ELT remote so we don't forget that thing as well. You don't have to put it on the panel in front of you.
