Hi all!I have been questioning myself about the accuracy of the fuel burn gauge in the lower EICAS. I have been doing numerous long haul flights with PIC, and have noted an average fuel burn readout of 1.7T per engine per hour.I have looked on airliners.net, and my videos and have noticed that on the same length flights, it has been around 2.7/2.5T per engine per hour.Is the gauge accurate?

Good question.I ran hours and hours of tests to tune the table that FSBuild 2.0 will use to calculate cruise fuel burn. Now I know you realize this but to everyones benefit who reads this, the burn is very dynamic as it has a large range of values based on altitude and GRWT. From what I can tell, it pretty closely follows what is actually flowing out of the PIC tanks. Those first few hours on a fully loaded flight indeed reflect the increased flow in that 2.7/2.5 area and then taper down to your 1.7 range at the end of the trip. Having said that, I still doubt the gauges a little bit sometimes after looking at my table numbers that were required to model the PIC flow. Email me and I will be happy to trade swap some data with you.p.s. I had to use a calculator to write about this because everything I worked out was in pounds.
