<td><strong>PURPOSE :</strong></td>
<td colspan="13"><p>The Aviation Forecast Preparation System (AvnFPS) is
the current computer application used by forecasters in NOAA's National
Weather Service (NWS) to prepare and monitor aviation forecasts. The
development effort linked to this ATAN is the architectural/functional
changes necessary to integrate a new tool into AvnFPS known as Tactical
Decision Aids (TDA). TDAs can provide National Airspace System (NAS)
decision makers the information needed to efficiently plan and direct
aviation traffic flow. The first of these TDAs under development
generates categorical forecasts of aviation impact variables, such as
ceiling and visibility, tailored to the needs of aircraft landing at and
taking off from an airport. Input for this TDA comes from the relevant
Terminal Aerodrome Forecast (TAF).</p>
<p>This ATAN supports the testing and review of the above AvnFPS TDA’s
design, operational and training effectiveness, and decision criteria
thresholds, using a test strategy that includes initially installing
AvnFPS ver. 3.4 at six WFOs, each supporting an adjacent Central Weather
Service Unit (CWSU).</p>
<p>CWSU forecasters will possess not only the capability to display TDA
products from their neighboring WFO, but also the capability to run the
AvnFPS application remotely from their ARD. Because of this, AvnFPS will
be delivered with the capability to block the inadvertent transmission
of TAF and TWEB products by CWSU forecasters. Creation and distribution
of TAFs and TWEBs remains the responsibility of the WFO.</p></td>

**Supplemental Information:**

Software being released under this ATAN is the same software bundle
being delivered to AWIPS contractor for OB8.1 delivery. This software
has undergone extensive regression testing and new features tested and
verified to work. This bundle has been successfully installed on NHDA
and TBW3.

I. ATAN Pre-Installation Steps

This part of the installation instructions must be completed prior to
executing the install/uninstall procedures included in sections II and
III. 

### A. Download ATAN 874 tar file from NOAA1 Server.

Perform the following steps to complete the download.

1.  As the user **root**, log on to dx1 from any linux workstation.

2.  Create the directory for this ATAN:

**mkdir /data/local/AvnFPS_ATAN_874**

3.  Change to the ATAN directory:

**cd /data/local/AvnFPS_ATAN_874**

4.  Obtain the tar file ATAN_874.tgz from the NOAA1 server, using the
    following commands:

**sftp ftpawips@165.92.25.137**

Enter the password when prompted. If prompted for the authenticity of
the host (RSA key), choose "yes" to continue connecting. Once logged in,
switch to the pub subdirectory and copy the file to your local AWIPS
machine as follows:

**cd pub**

**get ATAN874.tgz**

**bye**

### B. Untar ATAN File

Please verify that the file was successfully downloaded from NOAA1
Server by running the following command:

**/usr/bin/md5sum /data/local/AvnFPS_ATAN_874/ATAN874.tgz**

The resulting hash value should be:

**4f4858e5eb578cc071184e6a12e311ad**

Untar the contents of the ATAN_874 tar file using the command:

**tar zxf ATAN874.tgz**

The patch consists of two files, the install script and the tar file
consisting of the software bundle delivered with OB8.1 and two
supplemental scripts:

-   installAVNFPS.sh

-   AVNFPS3.4.tgz

-   runTDA.sh

-   runAvnFPS.sh

The additional scripts are meant to be placed on the CWSU's ARD machine
to allow CWSU forecasters access to AvnFPS software and the TAF Tactical
Decision Aid GUI.

II\. ATAN Install Steps

The script installs the software bundle in a new sub-directory under the
/awips/adapt/avnfps directory tree. The previous version of AvnFPS will
remain unaffected and will remain available for fall-back purposes.

1.  As **user root,** log on to dx1 machine from any linux workstation.

2.  Run the install script.\
    \
    **./installAVNFPS.sh /data/local/AvnFPS_ATAN_874**

3.  Log off dx1.
