Checking the news at Chongqing Jiangbei Airport officially启用s new Taxiway numbering and AIP 2015 Nr.08, the long-criticized “double-letter” taxiway numbering format at this airport has finally been changed to the standard “letter-plus-number” format, and officially commenced operations on July 23.

Comparing the new and old airport diagrams, first look at the previous numbering, For example, the exit numbers on the Taxiway in front of the Apron are AJ, AH, AG, BE, BD, AF, AE, B1, BC, BB, BA, showing no discernible pattern; it must have been very effortful for pilots to locate them on the charts every time.

Now look at the new diagram, the signage on the same Taxiway has been changed to A11, A10, A9, A8, A7, A6, A5, A4, A3, A2, A1, This is so much easier to understand; this is exactly how numbering should be.
