Huntsville International – Carl T Jones Field (HSV) is a medium sized, multi-use airport located between the cities of Huntsville and Decatur, Alabama. It has associated Class Charlie airspace and is in close proximity to restricted airspace. Also located close, just four miles northeast, is the Redstone Army Airfield (HUA) with its own Class Delta airspace. The runway configurations are somewhat similar and many pilots have mistaken HUA for HSV. During preflight planning pilots should review the rules and requirements for operating in and around the various types of airspace and make themselves aware of the nearby airfields.
