1. FAA’s Integrated Wind Shear Detection
Plan.
(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
(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.
