Abstract
A method and apparatus for selecting among a plurality of trajectories comprises receiving at least a first and second trajectory, each having an associated level in a trajectory hierarchy, determining whether the first trajectory is viable, determining a present level limit for trajectory selection, and if the first trajectory is viable and its level does not exceed the present level limit, executing the first trajectory. If the first trajectory is not viable or the associated level of the first trajectory exceeds the present level limit, the second trajectory is executed if it is viable and its associated level does not exceed the present level limit. A state variable is set such that when a trajectory lower in a trajectory hierarchy is executed, a trajectory selector waits for a message from a monitor or an operator before returning to the use of higher level trajectories.
