Methods for presenting traffic information on an aircraft display unit
First Claim
1. A method for presenting traffic information on an aircraft display unit, said method comprising:
- receiving data representative of ownship position from a navigation data source;
receiving first traffic data representative of first traffic comprised of at least one target from a first traffic data source;
receiving second traffic data representative of second traffic comprised of at least one target from a second traffic data source;
dividing the first traffic into third traffic and fourth traffic, wherethe third traffic corresponds to the first traffic located within a first zone of a plurality of zones, andthe fourth traffic corresponds to the first traffic located within a second zone which is a zone other than the first zone;
dividing the second traffic into fifth traffic and sixth traffic, wherethe fifth traffic corresponds to the second traffic located within the first zone, andthe sixth traffic corresponds to the second traffic located within the second zone;
determining whether there is a correlation between each target of the third traffic and each target of the fifth traffic if correlation information has not been received in either the first traffic data, the second traffic data, or both;
generating a traffic symbology data set comprised offirst traffic symbology data representative of first traffic symbology corresponding to each correlated target of the third traffic and the fifth traffic, andsecond traffic symbology data representative of second traffic symbology corresponding to each uncorrelated target of the third traffic or the fifth traffic, such thatthe first traffic symbology and the second traffic symbology are visually distinguishable from each other when presented on the screen of the display unit; and
providing the traffic symbology data set to a display unit, wherebyan image represented in the traffic symbology data set is subsequently presented on the screen of the display unit.

Abstract
Present novel and non-trivial methods for presenting traffic information are disclosed. In a first method, data representative of ownship position, first traffic, and second traffic are received by a traffic symbology generator (“TSG”). The traffic is divided into zones and a correlation between the targets of the traffic is determined. A traffic symbology data set is generated by the TSG based upon the results of the correlation(s). In a second method, data representative of ownship position and first traffic, runway references, and a selectable display range are received by the TSG. The traffic is divided into zones, and a traffic symbology data set is generated by the TSG thereafter. In a third method, data representative of ownship position and first traffic are received by the TSG. The traffic is divided into zones, and a traffic symbology data set is generated by the TSG thereafter.

8. A method for presenting traffic information on an aircraft display unit, said method comprising:
-
receiving data representative of ownship position from a navigation data source; receiving first traffic data representative of first traffic comprised of at least one target from a first traffic data source; retrieving runway reference data corresponding to at least one runway from a runway reference data source; receiving range data representative of a selected range of a display unit; dividing the first traffic into second traffic and third traffic, where the second traffic corresponds to the first traffic located within a first zone of a plurality of zones, where a size of the first zone corresponds to the selected range of the display unit, and the third traffic corresponds to the first traffic located within a second zone which is a zone other than the first zone, where a size of the second zone corresponds to a range exceeding the selected range of the display unit; generating a traffic symbology data set comprised of first traffic symbology data representative of first traffic symbology corresponding to the second traffic, and second traffic symbology data representative of second traffic symbology corresponding to the third traffic that is operating in an approach to landing and landing phase, missed approach phase, take-off phase, or a combination of any of these phases, such that the first traffic symbology and the second traffic symbology are visually distinguishable from each other when presented on the screen of the display unit; and providing the traffic symbology data set to a display unit, whereby an image represented in the traffic symbology data set is subsequently presented on the screen of the display unit. - View Dependent Claims (9, 10, 11, 12)

13. A method for presenting traffic information on an aircraft display unit, said method comprising:
-
receiving data representative of ownship position from a navigation data source; receiving first traffic data representative of first traffic comprised of at least one target from a first traffic data source; dividing the first traffic into second traffic and third traffic, where the second traffic corresponds to the first traffic located within a first zone of a plurality of zones, and the third traffic corresponds to the first traffic located within a second zone which is a zone other than the first zone; generating a traffic symbology data set comprised of first traffic symbology data representative of first traffic symbology corresponding to the second traffic, and second traffic symbology data representative of second traffic symbology corresponding to the third traffic, such that the first traffic symbology and the second traffic symbology are visually distinguishable from each other when presented on the screen of the display unit, and the second traffic symbology for each target, except for each target identified as operating in an emergency or rapid descent, is comprised of a dot without a traffic data tag; and providing the traffic symbology data set to a display unit, whereby an image represented in the traffic symbology data set is subsequently presented on the screen of the display unit. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
