An airspeed estimation system of an aircraft includes an electronic airspeed rate modeler unit configured to output an estimated airspeed rate signal indicating an estimated airspeed rate of the aircraft. The estimated airspeed rate signal is based on a longitudinal body acceleration of the aircraft and at least one adaptive parametric airspeed model. The airspeed estimation system further includes an electronic airspeed estimator unit in signal communication with the airspeed rate modeler unit. The airspeed estimator unit is configured to determine an estimated airspeed of the aircraft based on the estimated airspeed rate signal.
