WBcalc intentionally does not prefill a generic empty weight or empty CG for this page. Those values vary by individual aircraft and equipment configuration. Use the current certified weight and balance record for the airplane being loaded.
Primary source: FAA Type Certificate Data Sheet 3A12. This page represents FAA TCDS 3A12, Model 172D normal-category landplane.
Aircraft modifications, supplements, different serial-number configurations, floats, STCs or other approved changes can alter applicable limits. Confirm the data against the documents for the individual aircraft before flight.
