TSAT moment optimization method based on flight normality

An optimization method and normality technology, applied in the field of flight management, can solve the problems of not considering the situation of the aircraft on the airport flight surface, the flight cannot be executed on time, and the increase of carbon emissions, so as to improve the normality of the flight, reduce the number of waiting times, and improve the efficiency of ground resources. improved effect

Problems solved by technology

[0004] The existing TSAT calculation, on the one hand, does not take into account the actual security situation of the airport flight and the situation of the aircraft on the scene, which will cause the flight to fail to perform TSAT on time or cause scene congestion and wait at the end of the runway after the flight is launched, resulting in an increase in carbon emissions; on the other hand, For some airports that do not refer to CTOT to release flights, if the flight is guaranteed according to TSAT, it is easy to cause flight delays and reduce normality

Embodiment 1

[0065] The first step is to obtain the airport's runway clearance capacity table CAPS, the number of queues at the head of the runway N1, the target amount of early block removal N2, the clearance error N3 and the VTT table.

[0066] The second step is to read the flight information of the day, and establish a tsat computing pool and a dobt computing pool, expressed as:

[0067] [tobt≤T now +45min]∈tsat computing pool.

[0068] That is, put the flight whose tobt exists and is less than or equal to the current time +45min into the tsat calculation pool, put the flight whose eobt is less than or equal to the current time +90min and the tobt is greater than the current time +45min and all flights in the tsat calculation pool into the dobt calculation pool .

[0069] The third step is to uniformly adjust the flights on the same runway with the runway as the unit. Set the target start time t0 for the target runway.

[0070] Specifically, in this step, first, the departure time ...

Embodiment 2

[0081] For the estimated release time slot of each calculation target obtained in the eighth step in Example 1, optimize according to the following rules:

[0082] (1) slot-vtt-N1×gap>=tobt;

[0083] (2) ctot

[0084] (3) Any flight with normal clearance and normal departure will still maintain normal clearance and normal departure after optimization;

[0085] Among them, slot_y represents the estimated release time before each calculation target is not optimized in step S5.

Abstract

The invention provides a TSAT moment optimization method based on flight normality. The TSAT moment optimization method comprises the steps: counting flights planned to take off in a future time period of a preset time length and storing the flights into a preset tsat calculation pool; setting target starting time t0 for the target runway by taking the runway as a unit; counting available releasetime nodes of the target runway in combination with the target starting time t0 and the current runway release capability gap; allocating predicted release time nodes to the flights in the tsat calculation pool from the available release time nodes; for all flights in the tsat calculation pool, calculating the target departure time tsat based on the predicted release time node. According to the method, the TSAT moment is automatically calculated based on the flight normality and the runway head backlog condition, and the ground guarantee is considered through optimal scheduling of the tsat moment, so the ground resource efficiency is improved, and the executable degree of the TSAT moment is high; queuing waiting time of the runway head of the aircraft is reduced, and carbon emission is reduced; flight normality can be improved, and waiting sorts of aircrafts at the head of the runway are reduced.

Description

technical field [0001] The invention relates to the technical field of flight management, in particular to a TSAT time optimization method based on flight regularity. Background technique [0002] TSAT, that is, the target allowable driving time, in the link of flight release, it is equivalent to clarifying the time when the guarantee is over and everything is ready to launch at any time; a reasonable TSAT time can ensure that the flight can catch up with the release time of air traffic control on time, and it is the time for ground taxiing Provide a strong basis for scheduling and trolley resources. [0003] The existing TSAT time is generally issued by the air traffic control CDM system, and most of them are generated backwards based on the CTOT (that is, the calculated take-off time issued by air traffic control) time combined with the fixed taxi time of the airport. [0004] The existing TSAT calculation, on the one hand, does not take into account the actual security s...
