The invention belongs to the field of compensation for aircraft magnetic disturbance fields, and particularly relates to an aircraft magnetic disturbance field model parameter calculating method. The aircraft magnetic disturbance field model parameter calculating method comprises the steps of measuring an environment magnetic field of a tested area, measuring a fixed magnetic field and an inductive interference field of a carrier, calculating model parameters of the inductive interference field, measuring a vortex interference field of the carrier, and calculating model parameters of the vortex interference field. The three magnetic disturbance fields of the carrier are measured and calculated gradually in the testing process, and testing pertinence is enhanced; calculating errors caused by the carrier movement coupling according to a traditional method are avoided by effectively controlling the carrier to move; calibration flying necessary in the traditional method is avoided through off-line tests and calcu
