Wind Farms
The presence of wind farms within a flying area can cause the risk of that area to increase. We have cut out any wind farms from any polygons where they are present. New wind farms are being built all over. If you think that your flying area is being impacted by wind farms contact us at ahas@detect-inc.com.

warning !

The Avian Hazard Advisory System (AHAS) was constructed with the best available geospatial bird data to reduce the risk of bird collisions with aircraft. Its use for flight planning can reduce the likelihood of a bird collision but will not eliminate the risk. The AHAS organizations are not liable for losses incurred as a result of bird strikes.
