Abstract: A surveillance and collision avoidance system provides a presentation of situational awareness information for display that includes a compound symbol for each target spaced at a distance and bearing relative to a host symbol. The target compound symbol includes indicia of (a) whether the target is airborne or on the ground; (b) whether the target is a civil aircraft, a military aircraft identified as a formation member with the host aircraft, or a military aircraft not identified as a formation member with the host aircraft; (c) whether a ground track for the target is unknown, known by passive surveillance, or known by active surveillance; (d) for civil aircraft, whether the target is the subject of no advisory, a traffic advisory, or a resolution advisory; and (e) for a military aircraft, whether the target is the subject of no encroachment advisory, an unintended encroachment advisory, or an intended encroachment advisory. Subsystems selectively use an active or a passive mode of surveillance.

Abstract: A system and method for graphically controlling a communication device and displaying its characteristics on a display within a vehicle including a microprocessor, a communication and navigation information window within a portion of the display, the window being generated by and in communication with the microprocessor, at least one radio in communication with and controlled by the microprocessor, a data input means in communication with the microprocessor and at least one communication and navigation information database in communication with the microprocessor. An aircraft operator provides input to a cursor control device and receives visual feedback via a display produced by a monitor. The display includes various graphical elements associated with each radio's characteristics. Through the use of the cursor control device, the operator may modify the radio's characteristics and/or other such indicia graphically in accordance with feedback provided by the display.
