Dublin Point Merge procedure

什么是point merge?

Point Merge is a systemised method for sequencing arrival flows developed by the EUROCONTROL Experimental Centre in 2006.

Point Merge is now operational in Oslo (2011) and three Norwegian regional airports (2014), Dublin (2012), Seoul (2012), Paris ACC (2013), Kuala Lumpur (2014), Lagos (2014), Canary Islands (2014), Hannover (2014), Leipzig (2015) and London City and Biggin Hill (2016).

Point Merge is one of the ICAO Aviation System Block Upgrades and is referenced as a technique to support continuous descent operations (doc 9931).

Point Merge 是EURO CONTROL实验中心2006年开发的一种系统化的进场流量排序方法。2011年，在挪威OSLO机场开始实施（挪威另外三家机场于2014年开始实施）。

随后，都柏林（2012），首尔（2012），巴黎ACC（2013），吉隆坡（2014），拉各斯（2014），加纳利群岛（2014，汉诺威 （2014），莱比锡（2015），伦敦城市和比金山（2016）等机场陆续开始启用新程序。

Point Merge 是ICAO ASBU(航空系统升级组块)的一部分，也是支持CDO的关键技术之一。

简单说，就是随着航班架次增加，原有进场程序已不能满足需求（比如标准进场程序15分钟，而现阶段所有航班都需要飞行25分钟），那么多出来的10分钟就必须管制员用引导、等待等方式去消耗。

而频繁的引导和等待对于管制员和飞行员来说，都是效率不高并且存在安全隐患的一种选择。

所以我们希望，有一种办法可以尽量将这多余的10分钟也能够纳入到飞行程序体系之中来，尽量让航空器进场轨迹标准化，可预期化。

这就是point merge设计最初的目标。

这是全球第一个实施point merge程序的oslo机场关于该程序的介绍。

ICAO:EIDW

Implemented in December 2012, Dublin Point Merge streamlines the way in which aircraft are sequenced to land at Dublin Airport and uses new techniques to assist airlines to fly in Continuous Descent Approaches (CDAs) to the main runway. It has almost eradicated the need to put aircraft into traditional, circular holding patterns at Dublin and greatly reduces aircraft fuel burn and CO2 emissions.

An independent analysis conducted by NATS (UK Air Navigation Service Provider) established that by using Point Merge, airlines landing at Dublin Airport in 2013 saved 127 kg of fuel, worth €93.10 per flight and reduced their fuel requirement by 19.1% per flight. It also found that aircraft reduced the length of the flight by 11.3 miles, a 17% saving. Point Merge also provided savings of 23,500 tons of CO2, representing a 19% reduction.

Point Merge Extension to Runway 10

After the proven success of the introduction of Point Merge on Runway 28, the IAA introduced Point Merge to Runway 10.  The system lists among its benefits reduction in track mileage flown with consequent fuel saving, enhanced use of airborne avionics and continuous descent approaches and associated environmental benefits. The Runway 10 version differs from the Runway 28 system in that features individual sequence legs, positioned on the ideal track to final approach for Runway 10.

仅28/10跑道实施point merge程序，16/34并未实施。
