Fuel weight
Volume ↔ weight at the FAA handbook's working figures — avgas 6.0 lb/gal, Jet A 6.8 lb/gal (FAA-H-8083-1B pp.
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.
Labeled assumption — Uses the FAA handbook's working figures — avgas 6.0 lb/gal (FAA-H-8083-1B p. 7-7) and Jet A 6.8 lb/gal (nominal at +15 °C, p. 9-14) — not measured density. The same handbook's standard-weights table (Figure 3-4) lists 6.01 and 6.68 at 59 °F. Real fuel density varies with temperature; use metered figures when weight is critical.
Volume ↔ weight at the FAA handbook's working figures — avgas 6.0 lb/gal, Jet A 6.8 lb/gal (FAA-H-8083-1B pp. 7-7, 9-14): 50 gal of avgas is 300 lb on the weight-and-balance form. Standard weights, not measured density — cold fuel is denser, hot fuel lighter.
