Mass & Balance calculator

Work out zero fuel, take-off and landing weight and centre of gravity, check them against your aircraft's envelope, and export a signed-off sheet as PDF.

Enter every figure from your aircraft's own documents. Check every figure against your aircraft's own weight & balance report and flight manual. Calculation aid only; not approved flight-planning software. The pilot in command remains responsible. Only suitable where the approved W&B method can be represented by fixed station arms and a single fixed fuel arm — if your AFM/POH uses variable fuel moments, separate tanks with different arms, or special tables, use the approved method instead.
