Weight & Balance - Start/Taxi Fuel

A recent issue has surfaced where the W&B calculation from SkyDemon has been used for flight planning and the W&B figures entered into the Tech Log. The problem is the total weight on SD subtracts the Start/Taxi fuel, and so there is a discrepancy in the fuel and total weight figures.

This is fine if you're aircraft flight manual uses Max Takeoff Weight as a limit , however if it states Max Permissible Weight as a limit, you can easily fall foul during an audit.

SD is trying to be a little too clever. Can we please have simple W&B calculation that doesn't subtract Start/Taxi fuel.

Also, it's no good to say, set Start/Taxi to zero, as that will impact the fuel calculation.

I think a more useful improvement would be to graphically show the more complex W&B parameters on some aircraft. For example, one aircraft I fly (sub 2t SEP) has limits for max ramp weight (higher than max takeoff weight), max landing weight (lower than MTOW), and max zero fuel weight. None of these can be included in the current SkyDemon W&B model.
