FAA Aircraft Dispatcher (ADX)Navigation and ATCMedium
A VFR pilot plans to transit Class B airspace surrounding a major hub airport. Per 14 CFR 91.131, what must occur before the aircraft may enter that airspace?
- AThe pilot must file a VFR flight plan with the nearest Flight Service Station
- BThe pilot must obtain a transponder code from Flight Service prior to departure
- CThe pilot must establish two-way radio communication and receive a specific ATC clearance to enter
- DThe pilot need only monitor the tower frequency and announce position
Show answer & explanationAnswer & explanation
Correct answer: C. The pilot must establish two-way radio communication and receive a specific ATC clearance to enter
14 CFR 91.131 requires that no person operate an aircraft within Class B airspace unless the pilot-in-command has received a specific ATC clearance to enter (mere radio contact or being 'radar identified' is not sufficient). The aircraft must also have an operable two-way radio and appropriate transponder/ADS-B equipment.
Why the other options are wrong
- A. A VFR flight plan is not a substitute for the required ATC clearance.
- B. A discrete code from ATC (not FSS) is assigned only after clearance, not as a standalone requirement.
- D. Simply monitoring or announcing position does not satisfy the clearance requirement.
Class B Airspace Entry
Controlled airspace around the busiest airports requiring specific ATC clearance before VFR entry, in addition to radio and equipment requirements.
- Clearance phrase: 'cleared into Class Bravo airspace'
- Mode C transponder and ADS-B Out required
- Some primary airports require at least a private pilot certificate to operate
Memory trick: 'Bravo means Big clearance, Big equipment' — must be cleared in, transponder on
