I would love to install those in my plane. Any Mooney Service Center can order the parts. SWTA, DMax, LASAR, etc... 1 Quote Link to comment Share on other sites More sharing options...
0TreeLemur Posted August 8, 2018 Report Share Posted August 8, 2018 Good idea getting sight gauges installed. My model C has them. We checked their accuracy when we calibrated the fuel sending units after adding the JPI EDM900. They are accurate to within 1 gal. They "run out of gas" so to speak and don't really measure anything below about 5 gal so they are not good for the FAA mission of telling you when your tank is empty. In flight we cross-check them with the JPI fuel totalizer and the fuel sending units. I really like them. Another source of data for fuel management. 1 Quote Link to comment Share on other sites More sharing options...
