Shadin and the Hobbs.
Sorry to hear that Allan, surprisingly my gauges are some what accurate. I don’t normally top it off after every flight because of the weight factor carrying all that fuel, 148 gallons I feel is not necessary. What I do is keep as accurate a log as I can, recording Hobbs time in and out and Shadin readings in and out. I will periodically, maybe 6 or so flights top it off to see how accurate things have been and in between add fuel for the given mission. I like to have 4 to 5 hours of fuel on board for the 100.00 hamburger, visit the grand kids, fly ins etc. It consistently uses 22 gallons per Hobbs hour. The Shadin has always come out telling me that I have used more fuel than I have, but only a small percentage. I also keep her in a locked hangar. I like Bobs idea of the red tape when away from the locked hangar...
Guy, the old 72driver.... that beast would use on average 10,000 pounds per hour.
