FeatherWeight — W&B Calculator

Weight & balance for pilots

Free · Designed for iPad. Not verified for macOS.

Preflight weight and balance in seconds. Load your aircraft, watch the CG land inside the envelope, and export a trim sheet — on-device, no account, no network needed. FeatherWeight is a fast, focused weight & balance calculator for general aviation pilots. Build a loading plan in seconds, see exactly where your center of gravity falls inside the envelope, and export a trim sheet before you fly. BUILT FOR PREFLIGHT • Enter occupants, baggage, and fuel — weight and CG update as you type • Takeoff and landing points plotted directly on the CG envelope • Warnings when you exceed max ramp, takeoff, landing, or zero-fuel weight • Per-compartment baggage limits checked individually AIRCRAFT YOU ACTUALLY FLY • 13 built-in type templates: Cessna 152, A152, and 172 (M, N, P, R, S); Piper PA-28-140, -151, -161, Archer II and Archer III; Beechcraft BE-76 Duchess • Save your own aircraft using the actual empty weight and empty-weight CG from its weight and balance records • Normal, utility, acrobatic, and commuter categories, each with its own envelope FUEL PLANNING • Enter fuel by volume or by endurance • VFR day (30 min), VFR night (45 min), or custom IFR reserve • Expected burn folded into the landing weight and CG • Endurance recalculated as you move the tanks SHARE AND SAVE • Generate a PDF trim sheet for your records or your instructor • Save presets for the loadings you fly regularly • Pounds or kilograms, US gallons or liters, inches or centimeters PRIVATE BY DESIGN Everything runs on your device. No account, no sign-up, no network calls, no analytics, no data collection of any kind. IMPORTANT FeatherWeight is a planning aid only. It is not approved for official weight and balance calculations or FAA compliance. As pilot-in-command you remain solely responsible for verifying every figure against your aircraft's POH/AFM and its current weight and balance records before each flight.
