About AircraftOwnershipCost

AircraftOwnershipCost is written by James Johnston. We build simple calculators for US owners of small piston airplanes, with every default tied to a published source such as AOPA, airport fee schedules, AirNav or broker quote data, or labeled as an assumption. We are not insurance agents, lenders or mechanics. Questions or corrections: gencobusiness@yahoo.com.
