MGL Weight & Balance Function - How to create and load the files necessary to use the weight and balance function in the MGL iEFIS G3.

Thanks. This vid helped me with my MX1. I can confirm the fuel tank 2(1) is fuel tank 2 from RDAC 1 & is not one of the calculated tanks. Only issue I had was that the specified datum (Jabiru) had the pilot and passenger with a negative arm. Easy fix was to move the datum, but this means the diagram data (fwd and aft CoG limits don’t match the PoH, so someone unfamiliar might query this.

Thanks for the video. My question is in regards to the weight and balance definitions file. In the weight and balance definition from we have the W&B graph range. What determines those values? I setting up an RV8. Thanks

These values should be provided by the manufacturer. I think for an RV8 it is in Section 14 of the builders manual. Vans also have a summary weight & balance limits sheet on their website. So basically you will need a minimum and maximum weight, and a most forward and most aft C of G (measured in "inches aft of datum"). I notice for Vans aircraft they allow the builder to establish the maximum gross weight, but they do publish a "recommended" maximum gross weight. The minimum weight could be the empty weight or anything below that, to establish a "bottom" of the envelope. The RV8 has a design C of G range of 78.7 (most forward) to 86.82 (most aft) inches aft of datum.
