Arena Naming Convention
The naming convention used to designate runway corridors and protected areas (also called
"arenas") is as follows:
• The first 2 digits are the runway name, also referred to as the "corridor" name. In the
example, this is "33".
Corresponding names for the reverse direction (runway 15) are made automatically.
Vaisala recommends that you use the convention of naming the "north bound"
direction for a corridor.
• The next position is used if there is a left and right runway. For example, use 33R and
33L to indicate left and right runways.
If there is only a single runway, use a dash as in the example, that is, 33–.
Note, if the left and right runways are within approximately 500 m (1640 ft 5 in) of each
other, it is easier to designate a single corridor for alert purposes rather than have 2
separate corridors that are almost completely overlapped.
• The next field is an underscore character which serves as a separator.
• The last 3 digits are used to specify the "arena". In the example, "1MF" specifies a
protected area that extends from the end of the runway to 1 mile from the end of the
runway. It is recommended that you use the text RWY to specify the runway itself.
Once you have decided the runway and arena names, construct the geometry of the
protected areas, that is, the size and orientation information that is required in the IRIS
Setup > Product utility. See IRIS and RDA Utilities Guide.
