Claim Text:
1. A method of providing fault-tolerant lateral waypoint sequencing in a system comprising at least a first flight management computer and a second flight management computer, the method comprising the steps of: implementing, in the first flight management computer, a processing operation associated with lateral leg sequencing of an aircraft flight plan; implementing, in the second flight management computer, the processing operation associated with lateral leg sequencing of an aircraft flight plan; determining, in the first flight management computer, if the first flight management computer has received, within a predetermined period of time from when the first flight management computer implemented the processing operation, a notification from the second flight management computer that the second flight management computer has also implemented the processing operation; and initiating an action, in the first flight management computer, when the first flight management computer has not received the notification from the second flight management computer within the predetermined period of time, wherein the second flight management computer implements the processing operation associated with lateral leg sequencing of an aircraft flight plan without first receiving a request from the first flight management computer to implement the processing operation.
