for (iKey=0; iKeyJWAB (Javascript Weight And Balance) is a browser-based SPA (Single-Page Application) weight and balance app for freighter aircraft. I wrote it as an exercise to keep my aging brain active. I'm in my 80s now, but I still add to it from time to time. There was some thought that it might replace a DOS program I wrote that was used during the years 1988 through 2016 at three freight carriers, but that didn't happen. The DOS program handled Boeing 727, 747 and 767 aircraft, Douglas DC-8 and DC-9 aircraft, and Lockheed L‑1011 aircraft. The current aircraft in JWAB are just 747s and 767s.
\The app is freeware (GPLv3). Play with it if you like. Questions to Terry at terry.liittschwager@gmail.com.
\ \- \
- The POSITION REFERENCE DATA radio button menu on 747 aircraft pages now has three more options:\
- \
- “target offset” shows where each position is relative to the target zero fuel c.g. used by AUTO LOAD. \
- “zfw cg offset” shows where each position is relative to the current zero fuel c.g. \
- “sequence” is the position sequence number starting with one. \
\
- Test loads being used for development have a year of 2222 to keep them at the top of the SERVER Loads list, and the word TEST appears in place of the created time of day. \
- The weight unit default for N919YY and N952YY is kilograms. The default for all other aircraft is pounds. You can use the WEIGHT UNIT IN USE radio buttons to change which unit will be used in the display. Kilogram weights are in this color. Pound weights are in this color. \
- You can speed up the program by using the Toggle Plotting button to turn off the plotting. If a linear or cumulative limit is exceeded, the plotting is automatically turned back on so you can see what happened. \
