Advanced Drone Operations Certification Practice Exam

Two-way communication and separation for all aircraft define Class B airspace. This highly controlled environment surrounds busy airports, and entry requires explicit ATC clearance obtained through two-way radio contact. Once inside, ATC provides separation services to every aircraft, IFR and VFR alike, to keep traffic safely sequenced in a congested area. In contrast, other airspace types don’t offer this same combination: Class G is uncontrolled with no ATC separation, Class D involves two-way contact but ATC separation isn’t guaranteed for every aircraft, and Class E is controlled but doesn’t require two-way communication for VFR entry nor guarantee separation to all traffic.
