Two validation presets are included: 24 JUL (crew 2/4) and 23 JUL (crew 2/5).
Enter WBM DOW/DOI for the standard 2/4 crew; the selected crew correction is then applied once.
Graphical calculation
DOWZFWTOWLAW
Airbus-style graphical LTS: vertical axis is aircraft weight, horizontal axis is index,
diagonal lines are constant CG %MAC. The DOW, ZFW, TOW and LAW points are plotted exactly
as they would be read on the paper Load and Trim Sheet.
