The results are sent to a separate TDWR/LLWAS Integrator. The Integrator takes data from

LLWAS (if available) and conﬁguration information on the current active runways from the

runway utility. The output back to IRIS is a TDWR product that is ﬁltered so that only the

information required by the ribbon display is present. The integration algorithm is the

FAA/MIT Lincoln Lab algorithm that was developed for the U.S. FAA TDWR.

Usually both IRIS and the Integrator run on the RPG, although it is possible to run the

TDWR/LLWAS Integrator on an SD. This would, however, lead to conﬁguration chaos since

there are likely to be many SD's.

The RPG then outputs the TDWR product to the SD's and when it is received, it is

automatically formatted into a ribbon display message and sent out the SD serial line.

The process that outputs the products to the RBDT's has an additional conﬁgurable ﬁlter:

The controller can specify which corridors are displayed on an SD. Use the ribsetup to

conﬁgure this.

D.5 IRIS/TDWR Conﬁguration Summary

You must install and conﬁgure the TDWR components by performing the following

procedures.

1. Conﬁgure IRIS for TDWR operation.

a. Conﬁgure the runway arenas (protected areas).

See Conﬁguring Protected Areas (Arenas) for TDWR (page 338).

b. Conﬁgure the scan tasks and the SLINE and SHEAR products.

See Conﬁguring IRIS Tasks and Products for TDWR (page 340).

c. Conﬁgure the outputs to the Integrator and the SD's.

See Conﬁguring IRIS Product Outputs for TDWR (page 340).

2. Install and conﬁgure the Ribbon Displays. See:

• Ribbon Displays (page 342)

• Conﬁguring Ribbon Display Software (page 347)

3. Conﬁgure the TDWR/LLWAS Integrator (runways.conf).

See TDWR/LLWAS Integrator and Runways Utility (page 353).

4. Use the runways utility to set the runway direction.

See Runways Utility (page 360).

D.6

IRIS Preparation

Preparing the IRIS system involves setting-up the protected areas, scan strategy, product

generation, and output for TDWR operation.

D.6.1

Conﬁguring Protected Areas (Arenas) for TDWR

Protected areas are conﬁgured in the IRIS Setup > Product utility.
