Re: Fuel Log
I use the four column approach. Two columns each tank. Left one in ten minute intervals right one is litres remaining at the arbitrary school planning fuel flow figure. (ie 36 l/h C172, PA28, 40 l/h Arrow). The last 60 minutes (30 either tank) are marked off with a double line to indicate we are into reserves. Just cross off left or right tank at ten minute intervals and you have an instant estimate of what should be in your tanks, that you can compare with gauges and fuel flow indicator.
