Weight & balance (quick)
Free-form weight × arm accumulation: add a row per station and the panel keeps a running gross weight, total moment, and CG = total moment ÷ total weight (FAA-H-8083-1B p.
Reading the screen: cyan is a value you entered, green is a computed result, amber means a field still needs input or the entry needs a CHECK. SOLVED lights when every result is computed; STO keeps a value to reuse in another function; the line-select keys beside the screen pick the field the keypad edits.
Free-form weight × arm accumulation: add a row per station and the panel keeps a running gross weight, total moment, and CG = total moment ÷ total weight (FAA-H-8083-1B p. 2-3), through the same sumLoading core as the W&B sim. An optional reduction factor divides the DISPLAYED moment only, matching POH tables that print moment/1000. Accumulator only — no envelope check here; the full weight & balance tool plots your CG against the certificated envelope.
