ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent damage to
electronic circuits. Vaisala products are adequately protected against ESD
for their intended use. However, it is possible to damage the product by
delivering electrostatic discharges when touching, removing, or inserting
any objects inside the equipment housing.
To make sure you are not delivering high static voltages yourself:
- Handle ESD sensitive components on a properly grounded and
protected ESD workbench. When this is not possible, ground yourself
to the equipment chassis before touching the boards. Ground yourself
with a wrist strap and a resistive connection cord. When neither of the
above is possible, touch a conductive part of the equipment chassis
with your other hand before touching the boards.
- Always hold the boards by the edges and avoid touching the
component contacts.
Regulatory Compliances
The AviMet systems are designed according to the recommendations of
international air traffic authorities as presented in the following sources.
The algorithm used for calculations in the Vaisala AviMet® Low-Level
Windshear Alert System (LLWAS) is the latest version of the phase III
windshear algorithm developed for the U.S. Federal Aviation
Administration (FAA) by UCAR:
- United States Patent number 5,221,924: "Wind shear alert system",
W. Wilson, UCAR, CO.
- United States Patent number 5,208,587: "Low level wind-shear alert
system", L. Cornman, UCAR, CO.
- FAA LLWAS-III Specification.
The wind sensors of the LLWAS system are positioned and implemented
in accordance with the M.I.T., Lincoln Laboratories and the National
Center for Atmospheric Research system design guidelines specified in:
- Siting Guidelines for Low Level Windshear Alert System (LLWAS)
Remote Facilities. FAA Document Nr 6560.21A.

PRODUCT OVERVIEW
This chapter gives an overview of the AviMet system and its components.
System Introduction
Vaisala AviMet® Low-Level Windshear Alert System (LLWAS) is a
ground-based low-level windshear alert system. It provides visual and
audio alerts on calculated windshear and microburst conditions for air
traffic controllers and other airport personnel.
The system measures, processes, displays, stores, and distributes
meteorological information. It consists of sensors located along the
runway, one or two central data unit computers (CDUs), and one or several
workstations.
The sensors are located along the runways at specific measurement sites
and communicate with the central data units (CDUs), which distribute the
data to the workstations. The system can be single-CDU or duplicated, that
is, it can include one or two CDUs. The CDU validates the measurement
data, calculates the values based on the data, and distributes the weather
data and alarms to user workstations.
Vaisala AviMet® Low-Level Windshear Alert System (LLWAS) consists
of wind speed and wind direction sensors located around the runway area
perimeter. The CDU processes the horizontal wind speed and direction
data using the LLWAS III algorithm, developed by NCAR for the U.S.
Federal Aviation Administration (FAA). Windshear and microburst alerts
are provided when the data generated by the system exceeds the airport-
specific threshold values for possible windshear conditions.

In user workstations, users can view weather data and alerts with the
Weather View application. The values can be viewed in the ASCII Log
View application. The Diagnostics application is for monitoring and
handling system error situations.
A typical Vaisala AviMet® system is presented in Figure 1 on page 18.

AviMet® Product Platform
Vaisala AviMet® Low-Level Windshear Alert System (LLWAS) is part of
the AviMet technology platform. Other major systems based on the
platform are:
- Vaisala AviMet® Automated Weather Observing System (AWOS)
- Vaisala AviMet® Runway Visual Range System (RVR)
The LLWAS system can be an independent system or fully integrated into
the AviMet® AWOS system. The instructions in this manual generally
cover both versions, but if using the integrated version, note the differences
specified in the manual.
