Abstract: In one embodiment, a method for implementing a non-integrated CPDLC solution is provided. The method includes monitoring a datalink router for messages from a first CPDLC application in a first one or more execution partitions, wherein the first one or more execution partitions are configured to implement a first CPDLC application and wherein messages from the first CPDLC application and a second CPDLC application in a second one or more execution partitions use the datalink router to interface with one or more radio transceivers. The method also includes when the second CPDLC application has an active current data authority (CDA) air traffic control (ATC) connection, inhibiting communication between the first CPDLC application and an ATC ground station by discarding downlink messages of the first CPDLC application from the datalink router.

Abstract: A system and method is provided for displaying information related to an in-trail procedure (ITP) on a ITP display aboard a host aircraft. Current flight status data of the host aircraft and at least a second aircraft is obtained, and a vertical traffic scenario including at least the host aircraft ant the second aircraft is rendered on the display. A textual representation of a negotiation between ATC and the host aircraft is also rendered on the ITP display.

Abstract: Systems and methods for implementing non-integrated FANS/ATN CPDLC solutions are provided. In one embodiment a system comprises: a first computing system executing a first CPDLC application; a second computing system executing a second CPDLC application; at least one Human Machine Interface (HMI) coupled to the first computing system and the second computing system, the HMI configured to display screens generated by the first CPDLC application and the second CPDLC application; and a manager function that arbitrates HMI access to the screens generated by the first and second CPDLC applications. The manager function restricts access to one or more of the screens generated by the first CPDLC application based on a logon status of the second CPDLC application. The manager function restricts access to one or more of the screens generated by the second CPDLC application based on a logon status of the first CPDLC application.
