Introduce you to the AHAS system specifically for use in Alaska.

Overview

Radar CoverageRadar Coverageroutes and airfieldsroutes and airfields

Most routes and airfields are outside the NEXRADs 64 nautical mile radius for good bird detection

Areas that are outside of the 64 nm radius but within 133 nm will have a risk based on the nearest area within the 64 nm radius

Areas outside of the 133 nm radius of the radar will have a risk based solely on the BAM.

Radar CoverageRadar CoverageMOAS and rangesMOAS and ranges

Most of the MOAs and ranges are beyond the 64nm radius

MOAs and ranges that have a portion of their area within 64nm will have a risk based on the area that is within 64nm.

Areas outside of a 133 nm radius of the radar will have a risk based solely on the BAM.

Most MOAs will have BAM risk only

AHAS web pageAHAS web page The AHAS web page is at

www.usahas.com. Tabs at the top provide useful information.

AHAS now allows you to select Alert Areas and unit-specific Web Pages, if available

To request a unit specific page, contact the USAF BASH Team

You can also select output type

Table Output Table Output Current RiskCurrent Risk

Search Criteria: Current hour in Zulu(1), Elmendorf AFB (2,3), output choice (4)

For Alaska the current risk(5) is always based on NEXRAD data(6)

There are currently no soaring or migration models for Alaska so there is never a Height(7)

The table will automatically update every six minutes based on the current hour

Search Criteria: future hour in Zulu(1), Elmendorf AFB (2,3), output choice (4)

For Alaska, any hour that is not the current hour will result in a risk(5) based on BAM data(6)

Google Earth OutputGoogle Earth Output (available only on Google Earth enabled computers)(available only on Google Earth enabled computers)

Google Earth Enterprise Client Version 4.x is certified for use “with conditions” on the Air Force Global Information Grid, based on the due diligence checks validated by AFCA/EVSN as reported in the 07-07 Commercial off the Shelf Risk Assessment dated 7 Jul 07.

Only a United States Government (USG) controlled Google Earth Server can be used. The user has to obtain the Google Earth Enterprise Client software from the administrators of the USG controlled Google Earth server.

The decision to allow users to connect to non-secure servers, and to block or allow automatic updates should be made by Information Assurance Manager for the enclave the product is being used within.

Google Earth OutputGoogle Earth Output (available only on Google Earth enabled computers)(available only on Google Earth enabled computers)

Google Earth output is not available for unit-specific pages and Alert Areas

If you select this output, risk will be based on current AHAS readings

Automatically updates every six minutes based on current AHAS risk

Color defines warning level

Green = Low Yellow = Moderate Red = Severe

Google Earth APIGoogle Earth API (still in development, available soon)(still in development, available soon)

Same as Google Earth output embedded in AHAS web page

Provides many of the same layer options as the Map output.

Provides options not available in Map output

Does not require the Google earth program, but does require a downloaded Google earth plug in

Layers appear when checkbox is checked without clicking refresh

Points or polygons from any layer can be identified without selecting radio button and clicking refresh

Refresh button is used to change flying area, biweek, or time period

Google Earth APIGoogle Earth API (still in development, available soon)(still in development, available soon)

Sectional charts available as a layer

Sun rise layer also available

Terminal area charts available for a limited number of areas

Flyway charts available for a limited number of areas
