1 Alaska Avian Hazard Advisory System (AHAS) Alaska Avian Hazard Advisory System (AHAS)

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

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

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

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

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)

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
