1. A computerized system that continuously predicts a final aircraft state of a maneuvering aircraft provided a control input of the aircraft is at least one of released and relaxed, the system comprising:
- a computer processor;
and an algorithm programmed into said computer processor and adapted to calculate, during a maneuver, the predicted final aircraft state based on a mathematical command model, which comprises a basic heading and yaw rate response, comprising at least one of a desired final heading and a desired final pitch attitude, at least a first three derivatives of at least one of the desired final heading and the desired final pitch attitude, limiting values for each of the at least first three derivatives, closed loop algorithms, a plant canceller element, and a control input for at least one of the desired final heading and the desired final pitch attitude.

Abstract
Systems and methods are provided for determining a final heading of a turning vehicle, such as a rotorcraft. The system may include an algorithm that calculates an advance prediction of a final heading that will be achieved after control input is terminated.
