Gust Fronts.

1. FAA’s Integrated Wind Shear Detection


(a) The FAA currently employs an integrated

plan for wind shear detection that will significantly

improve both the safety and capacity of the majority

of the airports currently served by the air carriers.

This plan integrates several programs, such as the

Integrated Terminal Weather System (ITWS),

Terminal Doppler Weather Radar (TDWR), Weather

System Processor (WSP), and Low Level Wind Shear

Alert Systems (LLWAS) into a single strategic

concept that significantly improves the aviation

weather information in the terminal area.  (See

FIG 7−1−14.)

(b) The wind shear/microburst information

and warnings are displayed on the ribbon display

terminals (RBDT) located in the tower cabs. They are

identical (and standardized) in the LLWAS, TDWR

and WSP systems, and so designed that the controller

does not need to interpret the data, but simply read the

displayed information to the pilot. The RBDTs are

constantly monitored by the controller to ensure the

rapid and timely dissemination of any hazardous

event(s) to the pilot.
