Welcome to the Avian Hazard Advisory System (AHAS)!
We have updated the risk layers with 8 years of recent data and have simplified
the use of the AHAS. Previously, USAF and FAA users had separate map displays to
access the bird risk data. These options have now been combined to provide all
users with access to the numerous geospatial data themes along with the risk
Since 1995 there have been over 69,000 wildlife-aircraft
strikes recorded by the United States Air Force (USAF) that
killed 23 aviators, destroyed 12 aircraft, and caused more than $400 million
dollars worth of equipment damage.
The United States Avian Hazard Advisory System (USAHAS)
program objective was
to develop a predictive Avian Hazard Advisory System using Geographic
Information System (GIS) technology as a key tool for analysis and correlation
of bird habitat, migration, and breeding characteristics, combined with key
environmental, and man-made geospatial data.
