Question

In what class of airspace is no separation services provided to VFR aircraft but two-way communication must be established and maintained?

Answer 1

Class E airspace is the class of airspace where no separation services are provided to VFR aircraft, but two-way communication must be established and maintained.

Step-by-step explanation:

The class of airspace where no separation services are provided to VFR (Visual Flight Rules) aircraft, but two-way communication must be established and maintained is called Class E airspace. Class E airspace extends from 1,200 feet above ground level (AGL) up to, but not including, 18,000 feet MSL (mean sea level). In this airspace, VFR aircraft are required to establish two-way communication with air traffic control, but they are responsible for their own separation from other aircraft.
