3) And if the radar track in the correlation table of the current flight plan and the radar track does not receive a new input radar track with matched attributes in the radar track processing period, removing the correlation between the radar track and the flight plan in the correlation table of the flight plan and the radar track, adding the flight plan into an uncorrelated flight plan list, and adding the Lei Hang track into the uncorrelated radar track list.
4) And if the radar tracks existing in the current irrelevant radar track list do not receive the new input radar track with matched attributes in the radar track processing period, deleting the radar tracks in the irrelevant radar track list.
The flight plan management module monitors the plan updating prompt, actively acquires the updated flight plan after receiving the plan updating prompt, analyzes the flight plan, acquires the attribute information (secondary code, flight number, call sign and the like) and the state information (take-off and landing time, plan state and the like) of the flight plan, and updates the self-cached flight plan. Wherein, the plan updating reminding and the flight plan are generally provided by an external flight planning system.
