## What is FeatherWeight?

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.
