At what altitude does Class E airspace begin in the magenta "scuzz" area?

The correct altitude for the beginning of Class E airspace in the magenta "scuzz" area is 700 feet AGL (Above Ground Level). This specific characteristic of Class E airspace is important for pilots as it indicates the transition point where controlled airspace starts, which is designed to accommodate instrument flight rules (IFR) operations. The magenta "scuzz" on aeronautical charts visually represents the areas where Class E airspace starts at 700 feet AGL, typically in locations near airports that do not have a specific Class C or Class B configuration. Understanding this altitude helps pilots know when they need to communicate with air traffic control and comply with IFR requirements, making it crucial for flight planning and safe operations in that airspace.
