1. Alaska Avian Hazard Advisory System (AHAS)

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

3. Overview Radar coverage in Alaska
Current Conditions (current hour query)
Historical Conditions
Map option
Google Earth option
Google Earth API option
Overview

4. Radar Coverage routes 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.

5. Radar Coverage MOAS 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

6. AHAS web page
The AHAS web page is at 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
AHAS web page tabs
Alert Areas
Unit specific pages
Select output as a table, map, or with Google Earth

7. Table Output Current 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 1 2 5 6 7 3 4

8. Table Output Historical data
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)
There are currently no soaring or migration models for Alaska
The table will automatically update every six minutes based on the current hour 1 2 6 5 3 4

9. Map Output
Search Criteria: Current biweek(1) and time period(2) for Elmendorf AFB(3)
Must refresh map after adding layers or changing biweek, time period or flying area(4)
Change BAM layer by advancing by biweek or time period(5)
Must refresh map after selecting legend choices or identify tools before they appear on map(6) 1 2 3 4 5 6

10. Google Earth Output (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 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.

11. Google Earth Output (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

12. Google Earth API (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

13. Google Earth API (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

14. Google Earth API (still in development, available soon)
Transparent BAM layer
