Abstract: An ad-hoc secure communication network and methods of communicating with a fleet of vehicles using the ad-hoc communication network is provided. The method includes communicating relatively long range communication signals to a fleet router. The fleet router is a select one of the vehicles in the fleet. The method further includes forming an ad-hoc communication network between the fleet vehicles to communicate relatively short range communication signals between the vehicles in the fleet. Wherein each vehicle in the fleet uses surveillance information to determine the network topology and each vehicle routes messages based on the discovered network topology.

Abstract: An avionics system comprises a control device having an input/output interface to receive a Controller Pilot Data Link Communication (CPDLC) message; a textual-based Human-Machine Interface (HMI) coupled to the control device, the textual-based HMI operable to display textual content in the received CPDLC message based on instructions from the control device; and a graphical display unit coupled to the control device. The control device is operable to determine if graphical content is contained in the received CPDLC message. If the received CPDLC message contains graphical content, the control device is operable to send the graphical content to the graphical display unit and to provide instructions to the textual-based HMI to display a notification that the received CPDLC message contains graphical content.
