WBcalc is a model-specific aircraft weight and balance calculator and reference site for light aircraft. The goal is to make published loading data easier to use while keeping the aircraft-specific inputs that belong to the individual airplane clearly separate.
Each calculator combines model-specific limits such as maximum weight, CG envelope points, fuel stations, passenger stations and baggage limits with the current empty-weight data and planned loading entered by the user.
WBcalc identifies the source used for each model, such as an FAA Type Certificate Data Sheet, Pilot's Operating Handbook or Aircraft Flight Manual. Model applicability can vary by serial number, installed equipment, supplements and approved modifications.

WBcalc is a planning aid. The approved POH or AFM, current aircraft weight and balance record, equipment list and applicable supplements remain authoritative for the individual aircraft.
