I recently transitioned to the Cirrus SR22. I love the plane. But I hate keeping track of how much fuel I have in each tank. Since the Cirrus supplies fuel from one tank at a time to the engine, Cirrus pilots must remember to switch tanks periodically. And the aircraft is never supposed to have a difference of more than 10 gallons between the two tanks, for fear of instability.
While the instruments tell you the total amount of fuel consumed, they do not know which tank supplied the tool, so there is no record of how much fuel has been consumed in each tank. The fuel gauges themselves are notoriously unreliable.
My instructor for the transition taught me that the proper thing to do is to write down the total fuel consumed at each switch and do some quick math to see how much fuel has been consumed. Unfortunately, it can be hard to read my own handwriting, and it’s easy to make a math error.
I wrote the application to help replace that kneeboard reporting. I’d welcome any questions or feedback. If other pilots use the application, I may add more features.
