What type of airspace allows IFR and VFR flights while maintaining air traffic control separation?

Airspace that allows both IFR (Instrument Flight Rules) and VFR (Visual Flight Rules) flights while maintaining air traffic control separation is classified as Class B airspace. This type of airspace is typically found around busy airports and is designed to ensure that all aircraft can operate safely and efficiently in a high-density traffic environment.

In Class B airspace, air traffic control provides separation services to both IFR and VFR flights. This means that each aircraft is managed within a defined airspace structure, and pilots must obtain clearance from air traffic control before entering this airspace. As a result, there is a high level of oversight that helps to prevent any collisions or conflicts between aircraft.

The other classes of airspace—such as Class A, Class C, Class D, and Class E—have different operational rules and levels of separation provided. While many of these airspaces allow for both IFR and VFR operations, they do not necessarily guarantee the same level of separation provided in Class B airspace. For instance, in Class C and D airspace, separation is primarily provided to IFR flights with VFR pilots having to see and avoid other aircraft, which is less structured compared to Class B.
