10月24日 的 Weight And Balance Calculator 應用程式分析

Weight & Balance is a calculation assistant for general aviation pilots. Enter your aircraft profile (empty weight, empty arm, stations, MTOW, and envelope), then load fuel, passengers, and baggage to get total weight, moment, CG, and a clear within/out-of-envelope verdict — at takeoff and at zero fuel. FEATURES • Aircraft library — starter profiles for Cessna 152 / 172 (N, P, R, S), Piper PA-28-161 / PA-28-181, Piper PA-34-200 Seneca II (twin), Diamond DA-40. • Custom profiles — add as many stations as your aircraft needs (single-engine to twin), with seats, fuel, and baggage stations. • Envelope chart — plots your takeoff and zero-fuel points against the certified envelope, joined by a line showing how CG moves as fuel burns. • Zero-fuel check — zero-fuel weight and CG are shown alongside the takeoff result, with a warning if the zero-fuel CG falls outside the envelope. • PDF export — generate a printable / shareable W&B report with date, time, station table, totals, zero-fuel values, and the envelope chart. • Saved calculations — save any W&B result with a name, date, and full loading snapshot. Review past calculations from the Saved tab. Stored locally on your device. • kg/lb unit toggle — switch the entire app between kilograms and pounds in Settings. PDF reports follow your preference. • Avgas converter — Litres, US gal, IMP gal, kg, lb (100LL density 0.72 kg/L). • kg ↔ lb converter. • No ads. Works offline. Your aircraft profiles and saved calculations stay on your device. WHO IT IS FOR Student pilots, certified pilots, flight instructors, and flight schools using single-engine or light twin aircraft. IMPORTANT This app is a calculation assistant only. Always verify weight and balance using the official aircraft POH/AFM and current aircraft records before flight. The starter envelope and arm values are approximations — review and adjust each profile against your actual aircraft documents before use. PRIVACY No account or login. No ads, no tracking.
