WandB is a tk program to draw a W and B plot. The parameters for the airplane are entered into a graphical window, and then you can experiment with various configurations, fuel loads etc. to see how your total weight and C.G. location change. Fuel is specified with a slider so the effect of fuel burn on CG may be observed.
WandB [-D datafile-directory] [config-name]
datafile-directory(the user's home directory by default) and the string
.wnbis appended to the config name. If run without a config name, WandB will bring up the data entry window where you can enter the W and B information and then save it as a config file. Some sample .wnb files are provided.

Entering (or editing) an airplane's parameters
To run WandB you must have tcl/tk installed. tcl-7.4 and tk-4.0 are required, but tcl-7.5 and tk-4.1 are strongly recommended. Source code is freely available; and pre-compiled binaries for Unix systems may be purchased. MS-Windows binaries may be obtained from ftp.sunlabs.com. Mac executables are also available.
No warranty of any sort is offered! I wrote the program for myself, and am distributing it in the hope that someone else might find it useful. For entertainment purposes only! Batteries not included.
