1. An aircraft system for an own-ship aircraft, comprising:
an Automatic Dependent Surveillance-Broadcast (ADS-B) unit configured to receive ADS-B messages with flight information from other aircraft over a plurality of time periods, the other aircraft including a first aircraft; a database coupled to the ADS-B unit and configured to store at least a portion of the flight information associated with the other aircraft over the plurality of time periods; a processing unit coupled to the ADS-B unit and the database and configured to compare the flight information for a current time period to the flight information for a previous time period to identify missing flight information from the current time period relative to the previous time period, the missing flight information including the flight information associated with the first aircraft, wherein the flight information in the ADS-B messages include, for each of the other aircraft, an aircraft identification, a position, an altitude, and a time stamp to identify the respective time period, and initiate an annunciation to an operator of the own-ship aircraft based on the missing flight information associated with the first aircraft, wherein the processing unit is configured to identify the missing flight information associated with the first aircraft when a time elapsed between the time stamp associated with the most recently received ADS-B message from the first aircraft and the current time period exceeds a predetermined threshold; and a display device coupled to the processing unit and configured to display the annunciation, wherein the processing unit is configured to evaluate the flight information for the current time period to identify proximate aircraft from the other aircraft and to display a traffic display on the display device with the annunciation that includes at least first icons representing the proximate aircraft, wherein the annunciation includes a text annunciation associated with the first aircraft, and wherein the text annunciation associated with the first aircraft includes the aircraft identification, the position, and the altitude from the most recently received ADS-B message from the first aircraft, the text annunciation further including the time elapsed between the time stamp associated with the most recently received ADS-B message from the first aircraft and the current time period. |
