Performance Calculation
After evaluating some different tools for the weight and balance report, performance, and fuel calculation I got stuck with TOPCAT. For me TOPCAT is the most advanced program for Weight and Balance, Take-Off and Landing Performance calculation. In addition it does also a basic fuel calculation which is very close to the actual consumption.

TOPCAT calculates the ZFW by means of the dry operating weight (DOW), and payload. During flight preparation ZWF is entered by the pilot into the .PERF INIT page  of the CDU.
