Systems and methods are disclosed herein to provide trim for a vehicle, such as an aircraft. For example, a method for providing trim may include generally simultaneously determining values for a plurality of trim variables in a plurality of degrees of freedom. In this manner, the iterative aspect of contemporary methods for providing trim is substantially mitigated and a more efficient, robust system is provided.

I claim: 1. A method for trimming a vehicle'control surfaces and propulsion system thrust to achieve or maintain a target state of the vehicle defined by its position, velocity and acceleration relative to a coordinate system, the method comprising:using at least one sensor to determine the current state of the vehicle; and,using at least one processor:comparing the current state of the vehicle to the target state;defining target values of linear and angular acceleration components of the vehicle, each expressed as a function of one or more trim variable, required to transform the state of the vehicle to or maintain it in the target state; and,simultaneously determining trim values of all of the trim variables required to drive the current values of the linear and angular acceleration components of the vehicle to the target values thereof.
