Conjecture method of dynamic flying track

This paper studied the algorithm of flying track conjecture by using the principium of garden line and angle line conjecture combined with the dynamic data of radar and flight telegraph, calculated the flying track and fix point time of aerocraft, and estimated air traffic flow by the method, the result was compared with that by experience time add-up method with the flight plan data of airport ZGGG. It is pointed that dynamic flying track conjecture method has high sensitivity, its error is within ±0.5 min, it accords with fly rules, and can revise the fly route in real-time. The results indicate that dynamic flying track conjecture method could estimate the flow of airspace more accurately, is an effective measurement for tactical air traffic flow management.
