Abstract
Context-Sensitive Reference (CSR) for situational awareness, and associated methods and systems are disclosed. A system in accordance to one embodiment includes an aircraft display system having a traffic application with traffic symbols representing traffic aircraft and a CSR associated with traffic aircraft displayed proximate to the respective traffic symbol. The CSR improves situational awareness of the traffic scenario by further refining the depiction of actual traffic on a traffic display relative to own-ship suitable to the traffic situational awareness need at hand. Such depiction may be in time or distance relative to own-ship or to fixed structure, and engaged in an automatic or manual mode.
Claims21
A system for displaying vehicle traffic comprising:
- a dynamic symbology displayed on a display system, said dynamic symbology comprising at least one vehicle symbol depicting traffic information and an indicator proximate to the at least one vehicle symbol, wherein the location of said indicator is based on own-ship's sensitivity to a relative position of the vehicle traffic depicted by the at least one vehicle symbol.
An aircraft system for displaying traffic comprising:
- an airplane surveillance system;
- a traffic application operatively connected to said surveillance system;
- a cockpit display system operatively connected to said traffic application;
- a navigation system operatively connected to said traffic application;
- a control input device operatively connected to said surveillance system and said traffic application;
- and
- a dynamic symbology displayed on said cockpit display system wherein said dynamic symbology includes a vehicle symbol depicting traffic information and an indicator proximate to said vehicle symbol wherein a location of said indicator is based on ownship's sensitivity to a relative position of the traffic depicted by said vehicle symbol.
A method for displaying traffic information on a cockpit display system, comprising:
- initiating a traffic application;
- providing control input for said traffic application;
- receiving traffic information;
- determining own-ship's position;
- processing said traffic information combined with own-ship location information;
- generating exact traffic position or enhanced traffic position based on said control input;
- and
- displaying said exact traffic position or said enhanced traffic position based on said control input, said exact traffic position or enhanced traffic position displayed using a dynamic symbology, wherein the dynamic symbology comprises at least one vehicle symbol depicting said traffic information and an indicator proximate to the at least one vehicle symbol, the location of the indicator based on own-ship's sensitivity to a relative position of the other aircraft depicted by the at least one vehicle symbol.
A method of indicating a relative position of vehicle traffic on a display, the method comprising:
- displaying a map having a distance scale on a graphical display, the map capable of representing a plurality of distance scales;
- displaying a location of at least one traffic vehicle by a traffic vehicle symbol on the map, the traffic symbol having a fixed size regardless of the distance scale of the map displayed;
- displaying an own-ship vehicle symbol;
- determining own-ship's position;
- and
- displaying an indicator proximate to the traffic vehicle symbol, the indicator smaller than the traffic vehicle symbol, wherein the indicator placement more precisely represents a relative position of the at least one traffic vehicle on the map.
