A flight deck system is configured to: receive a data model populated with flight data obtained while performing a core avionics function; receive configuration information from an external source that identifies a specific plurality of flight data items to extract from the data model; extract from the data model data values for the specific plurality of flight data items identified in the configuration information; generate an optical code that encodes the extracted data values; generate an HMI display that provides a selectable link for causing the optical code to be displayed in the aircraft; cause the HMI display to be display on an aircraft display; and cause the optical code to be displayed on an aircraft display responsive to selection of the selectable link; wherein the optical code provides encoded data values corresponding to the specific plurality of flight data items for decoding and display by a mobile device.
