fyiEstimate values are market estimates from comparable asking prices (which skew high versus sold prices), not certified appraisals. Fleet and ownership figures from the FAA Releasable Registry; "registry transfers" count new registration certificates issued. Sold records from aircraft.com reflect the last asking price, not the transaction price. Monthly history is reconstructed from when listings first and last appeared.
