Which of the following is NOT a characteristic of Class E airspace?

Class E airspace is designated as controlled airspace, which is defined by specific operational rules and regulations designed to ensure safety for all aircraft operating within it. Characteristic of Class E airspace, it allows for various levels of airspace management, but it operates under less stringent conditions compared to Class A, B, or C airspace.

The classification of controlled airspace includes Class E, which is utilized for both IFR (Instrument Flight Rules) and VFR (Visual Flight Rules) operations. The benefit of Class E airspace is that it provides a safe environment for aircraft as they transition through different airspace classes without the need for direct air traffic control, especially at lower altitudes.

It also includes characteristics such as: containing low-level airways and allowing for VFR flights without prior permission. Furthermore, Class E airspace can extend from either the surface or from a specified altitude, often starting at 1,200 feet AGL.

Understanding Class E airspace as controlled airspace is crucial for pilots so they can effectively navigate and comply with relevant regulations, ensuring safe flight operations.
