Areas beyond 150 miles of a NEXRAD
There were 50 areas in AHAS that were more than 150 miles from the nearest NEXRAD station. These areas have been removed. Some segments of routes and MOAs that are beyond 150 miles of the radar remain in AHAS to complete the route but will have no data.

When you select the ICAO area type there is a new option available. In the "Select Flying Area" dropdown list you can select "List". When you click one of the buttons a pop-up box will appear where you can enter a list of ICAO codes separated by a comma (kaby,ktlh,kbix). When you click "ok" in the pop-up box, the button you selected will activate.

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.
