D.7.4 IRIS Virtual Ribbon Display
For systems that do not have the Dale model ribbon display, the IRIS Virtual Ribbon Display
(
vribbon
) is provided.
It is also convenient for "eaves dropping" on Dale displays to verify that they are properly
configured, that is, you can look at a virtual version of the Dale display.
Observers, Operators, and Controllers can access the
vribbon . The vribbon display is run
locally on an SD by opening a terminal and typing:
$ vribbon
Figure 122 vribbon Display
The display has 10 lines. The top nine lines are used to display warnings for various approach
and departure corridors. In the example, runway 15 departure has a microburst alert with a
45 knot loss. The threshold winds are reported as 60° (
060 ) at 13 knots. The bottom line
shows the center field wind data and the status of the alarm signal.
The
vribbon
can show any of the 8 physical ribbon displays. This is done by selecting the
display number (0 ... 7). The
vribbon
display also has a tone alarm that can be silenced
(not disabled) by selecting Acknowledge .
