2015年12月4日,中国民用航空局(以下简称中国民航局)对航线时刻资源进行改革,实行“时刻拍卖”或“时刻抽签+使用费”。一石激起千层浪。我国地面交通资源有限,车牌要摇号,车辆要限行。没想到,长期以来,天上的交通资源同样紧张。2014年,我国繁忙航段日均流量超过500架次的有13条。其中,最繁忙航段日均流量超过1100架次。天上的道路如此拥挤,让谁飞?谁该飞?到底谁说了算? On December 4, 2015, the Civil Aviation Administration of China (hereinafter referred to as CAAC) conducted a reform on route resources at all times and implemented “Auction of Time” or “Lottery Draws + Use Fee”. A stone aroused Melaleuca waves. China’s ground transportation resources are limited, plate number to Yaohao, vehicles to limit. Unexpectedly, the transportation resources in the sky have been equally tense for a long time. In 2014, there were 13 daily traffic volumes exceeding 500 in China’s busy sections. Among them, the daily average flow of the busiest section of more than 1,100 sorties. So crowded in the sky, who fly? Who should fly in the end who have the final say?
