An avionics system comprising a human machine interface configured to display a user interface and a control device is provided. The control device coupled to the human machine interface, wherein the control device is configured to send and receive controller/pilot data link communications (CPDLC) messages and adjust the user interface based on a first CPDLC version of an established first CPDLC session.

Enhanced flight crew display for supporting multiple controller/pilot data link communications (CPDLC) versions

A system to reduce head-down time for a flight crew member is provided. The system includes a functional module that includes a set of screens used to receive and send controller pilot data link communications (CPDLC) messages between an aircraft and a ground-based system; a message composition screen communicatively coupled to the functional module; and a shortcut interface communicatively coupled to the functional module, wherein a shortcut prompt is displayed when one of a response timer expires or a negative uplink response message is received responsive to a previously-sent downlink request message, wherein an implementation of the shortcut interface generates a 'when can we expect . . . ' message related to the previously-sent downlink request message.

Automatic presentation of a 'when can we . . . ' message composition screen responsive to a negative response message

A system to reduce head-down time for a flight crew is provided. The system includes a functional module including a set of screens used to receive and send controller pilot data link communications (CPDLC) messages between an aircraft and a ground system; a message composition screen communicatively coupled to the functional module; and a shortcut interface communicatively coupled to the functional module, wherein a shortcut prompt is automatically displayed when a confirm-response message received responsive to a previously-sent downlink request message is viewed, and wherein the previously-sent downlink request message is displayed when the shortcut interface is implemented.

Automatic presentation of a shortcut prompt to view a downlink request message responsive to a confirm-response message

A method to indicate a transitional operational state of a communication link is provided. The method includes indicating the operational state of the communication link is operable, transmitting data between a communication management unit and an endpoint via the communication link, and determining if the transmitted data is received at the endpoint. The method also comprises continuing to indicate the operational state of the communication link is operable when the transmitted data is received at the endpoint and determining if a transport layer has timed out when the transmitted data is not received at the endpoint within a pre-selected time. The method also comprises indicating the operational state of the communication link is transitional when the transport layer has not timed out and the transmitted data is not received at the endpoint within the pre-selected time.
