Bad fuel gauges?
Despite my years of fighting ignorance, many pilots still seem to
believe that the fuel gauge only has to be accurate when it reads 0. In fact, I have seen both Rod Machado and the Kings assert this. We have an uphill fight, my brother. -- Waddling Eagle World Famous Flight Instructor- Hide quoted text - - Show quoted text - Rod Machado. I have his audio CD book and it may well be that this is where I heard the idea of being accurate only when full or empty. I can't remember at the moment but I'll find out. An earlier post explained the guage can be off by as much as four gallons. Is that far enough off to not meet regulations? Well, the important thing to note is they are not accurate. The only sure-fire method of tracking your fuel, it seems to me, in a GA aircraft, is to measure starting values, measure your actual consumption after shutdown, compare to the TDF to climb & cruise performance charts. Especially if you plan your flight down to the reserve! (Does anyone really plan to stretch fuel use clear to the limit of the regs?) |
