Fault tolerant lateral waypoint sequencing system and method
First Claim
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.

Abstract
Fault-tolerant lateral waypoint sequencing is provided for a system that includes at least a first flight management computer and a second flight management computer. A processing operation associated with lateral leg sequencing of an aircraft flight plan is implemented in the flight management computers. A determination is made in the first flight management computer as to whether 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 has also implemented the processing operation. An action is initiated 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.

12. A flight management system that provides fault-tolerant lateral waypoint sequencing, comprising:
-
a first flight management computer configured to implement a processing operation associated with lateral leg sequencing of an aircraft flight plan; and a second flight management computer in communication with the first flight management computer, the second flight management computer configured to also implement the processing operation and, upon implementing the processing operation, to transmit a notification to the first flight management computer, wherein; the first flight management computer is further configured to initiate an action when the first flight management computer has not received the notification from the second flight management computer within a predetermined period of time from when the first flight management computer implemented the processing operation, and 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. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
