← All explained questions · Airspace and Operating Requirements
A pilot establishes two-way radio communication but receives no explicit clearance. Which airspace may they NOT enter?
Choices
Class D
Class D only needs two-way communication, which was established.
Class C
Class C needs two-way communication plus equipment, not an explicit clearance.
✓ Class Bcorrect
Class B requires an explicit clearance, which was not received.
Class E
Class E needs no clearance for VFR.
Why
Only Class B requires an explicit clearance to enter. With communication established but no clearance, the pilot may enter C, D, and E (given proper equipment) but not B.
