7.6 过渡识别符
SID/STAR的跑道过渡识别符，使用RW后随跑道号码组成。如果过渡应用于平行跑道，该过渡识别符也只需编一次码，但要在跑道后加一个B字。
SID/STAR Runway Transition Identifiers will be established using the characters RW (for runway) followed by the runway number. If a transition applies identically to parallel runways, the transition need only be coded once for the parallel runways. In those cases, it should be identified with a suffix of “B” after the runway number.
例：08L 08R是标准的，编为RW08B即可，不用重复跑道号码，写成RW08L/RW08R.
进近过渡识别符通常用导航台的呼号或过渡航段的起点的航路点的识别符或使用官方数据源中的命名。当然为了保证过渡识别符的唯一性，也可能会修改。
Approach Transition Identifiers are normally the identifier of the NAVAID or Waypoint at which the transition starts or as published in official government source. These identifiers may be modified to ensure a unique identifier is available for each transition.
