Controlled Airspace is characterized by which of the following?

Controlled Airspace is characterized by which of the following?

• A. Not controlled by ATC
• B. ATC service is provided and split into High Level Airspace and Low Level Airspace
• C. IFR only
• D. No transponder required

Answer: (B)

Controlled airspace is the airspace where air traffic control provides separation services to aircraft and pilots operate under ATC instructions or clearances. This is why the defining feature is the presence of ATC services. It’s also commonly described as having two main segments—high level airspace and low level airspace—so different altitude ranges and procedures are defined within the same controlled framework. Seeing ATC service described and the division into high and low levels matches how controlled airspace is organized in practice. The other statements don’t fit: saying it’s not controlled by ATC would describe uncontrolled airspace, IFR-only ignores that VFR operations can occur within controlled airspace, and no transponder requirement isn’t universally true for controlled airspace, where transponder use is often required to help ATC manage traffic.
