#Aviation Weight/Balance Calculator

This program makes it easy to do your weight and balance calculations so you can determine your position in the performance envelope before you take off into the wild blue yonder!

Program screenshot.


No nice executable, but you can get it going like this:

  • Download and install Java -- used for the GUI.
  • Download and install newLisp -- language this is written in.
  • Download wb.lsp to somewhere convenient.
  • Run with command "newlisp wb.lsp".

To use:

  • Enter the appropriate numbers for your airplane -- see Section 6, Weight & Balance of the POH.
  • Use [tab] to jump between fields.
  • Use [enter] to recalculate result.

This form uses the Island Air Flight School format.


See the newLisp forum thread or archived.


I believe that this program works as described, but any use is at YOUR OWN RISK.
