  2. If there is a named waypoint on an airway which crossed an irregular FIR/UIR boundary, the waypoint coordinates will be used to define a point in the path defining that FIR/UIR boundary. The Boundary VIA will appropriate to the path definition.
  2、如果有一个命名航路点在穿越不规则的FIR/UIR边界的航路航线，该航路点的坐标应用于定义FIR/UIR边界线上的一点。该边界途经点适用航径定义。
  3. Paths that follow lines of latitude will be coded with a Boundary Via of “H”. Paths that follow lines of longitude may be coded with a Boundary Via of “G” or “H”. Consistent use of one or the other with a single airspace is desired.
  3、边界线随纬线走向时，填写编码H。边界线随经线走向时，填写G或H。最好一个空域固定用一种或另一种方法。
  4. Other than for lines of latitude and longitude, the Boundary VIA of “H” shall only be used when specifically stated in the official government source. If not stated as “Rhumb Line” or not along latitude/longitude, all straight lines will be coded as “G”.
  4、经纬线以外的其它形式，当官方资料中特殊说明的，本项必须填写H。如果未说明是等角线或者不是沿经纬线的所有直线，均填写G。

  Note: Refer to Figure 5-12 for sample coding of Boundary VIA Codes.
