Trailing interval flow control scheme rationality assessment method

Abstract

The invention relates to a trailing interval flow control scheme rationality assessment method. The trailing interval flow control scheme rationality assessment method comprises the processes of utilizing a data source under the condition without trailing interval limitation to assess accuracy of demand predication and capacity prediction and to eliminate interference of MIT (miles-in-trail) factors, and establishing a demand prediction and capacity prediction accuracy probability computing method; based on different demand and capacity prediction accuracies, establishing a process for assessing the rationality of MIT under the condition of taking trailing interval flow control measures; determining capacity influence rates f(CERXt) of different weathers; analyzing consequences and possible reasons due to the fact whether the MIT is implemented under different predicting conditions. The trailing interval flow control scheme nationality assessment method improves the current situation of incapability of assessing rationality of existing MIT flow control measures, lays foundation for enhancing and improving trailing interval control schemes, achieves effective supervision of every airspace control units, improves the air traffic efficiency and the management level, avoids airspace resource waste, improves the on-schedule rate of flights and reduces flight delay.

Description

Technical field [0001] The invention relates to the field of transportation, in particular to a method for evaluating the rationality of a trailing interval flow control scheme. The evaluation method focuses on the category of traffic flow management in civil aviation, and mainly evaluates the rationality of a trailing interval control scheme in a region or terminal area. Background technique [0002] At present, Air Traffic Flow Management (ATFM) commonly used worldwide is based on Ground Delay Program (GDP) and Traffic Management Advisor (Traffic Management Advisor, TMA), followed by Interval (Miles-in-trail, referred to as MIT) is suitable for temporary flow control technology, which has great research value; [0003] Since China has not yet established a unified flow control center, technologies such as GDP and TMA cannot effectively play their due role. In the practice of air traffic flow management, the most commonly used active traffic management method (Traffic Management I...

Problems solved by technology

[0003] Since my country has not yet established a unified traffic control center, technologies such as GDP and TMA cannot effectively play their due role. In the practice of air traffic flow management, the most commonly used active traffic management methods (Traffic Management Initiatives, TMIs for short) ) is MIT, but the current implementation of MIT basically depends on the work experience of the controllers; when the airspace capacity is affected by bad weather or military activities, the MIT flow control scheme is greatly affected by the subjective factors of the flow control personnel; Income is not linked to the number of support sorties. When the airspace is affected by weather and military activities, the controllers are very likely to use the excuse of ensuring flight safety to slow down and reduce the number of support sorties; Whether the parameters are reasonable has been questioned; and so far, there is no mature method for evaluating the rationality of MIT at home and abroad. MIT's flow control measures are being rectified. This situation restricts the improvement of air traffic operation efficiency and management level, and also buryes the hidden danger of waste of airspace resources.
