What is the assumed starting altitude for Class E airspace when no Magenta Band is present?

• A. 700 feet AGL
• B. 1200 feet AGL
• C. 18000 feet MSL
• D. 5000 feet MSL

Answer: (B)

The assumed starting altitude for Class E airspace when there is no Magenta Band present is indeed 1,200 feet AGL (Above Ground Level). Class E airspace is often designated in various ways, and the lack of a Magenta Band indicates that the airspace extends from the surface to the base of the overlying airspace above. The 1,200 feet AGL threshold is significant because it establishes a boundary under which visual flight rules (VFR) operations tend to dominate, while also considering the altitude where air traffic control services may initiate. Pilots must be aware of this altitude for maintaining appropriate separation and ensuring proper communication with air traffic control, especially while flying in or transitioning through areas with mixed class airspaces. In general, knowing the starting altitude of Class E airspace helps pilots maintain safe altitudes concerning their flight plans, avoiding potential conflicts with other aircraft.
