CFC CFC Airspace Classification & Communication Requirements 1 — Questions and Answers
Question 1: What communication equipment is required to operate in Class A airspace?
- VHF radio only
- Two-way radio communication with ATC and an IFR clearance (Correct answer)
- Transponder only
- No equipment required
Correct answer: Two-way radio communication with ATC and an IFR clearance
Class A airspace requires two-way radio communication with ATC and a valid IFR clearance and flight plan.
Question 2: At what altitude does Class A airspace begin in the contiguous United States?
- 10,000 feet MSL
- 14,500 feet MSL
- 18,000 feet MSL (Correct answer)
- 24,000 feet MSL
Correct answer: 18,000 feet MSL
Class A airspace extends from 18,000 feet MSL to FL600 in the contiguous US.
Question 3: What is required before entering Class B airspace?
- An explicit ATC clearance (Correct answer)
- Filing a VFR flight plan
- A Mode S transponder only
- Student pilot endorsement only
Correct answer: An explicit ATC clearance
An explicit ATC clearance is required before entering Class B airspace surrounding the nation's busiest airports.
Question 4: Class C airspace typically has what horizontal configuration from the primary airport?
- 5 NM inner circle, 10 NM outer circle (Correct answer)
- 5 NM inner circle, 15 NM outer circle
- 10 NM inner circle, 20 NM outer circle
- 3 NM inner circle, 5 NM outer circle
Correct answer: 5 NM inner circle, 10 NM outer circle
Class C airspace has a 5 NM inner circle and a 10 NM outer circle, creating a characteristic two-ring structure.
Question 5: What communication requirement applies when entering Class C airspace?
- No communication required in VFR conditions
- Two-way radio communication must be established with approach control (Correct answer)
- File a VFR flight plan with FSS
- Obtain an explicit ATC clearance like Class B
Correct answer: Two-way radio communication must be established with approach control
Two-way radio communication must be established with ATC before entering Class C airspace, though an explicit clearance is not required.
Question 6: Which airspace class requires both an ATC clearance AND a filed IFR flight plan for all operations?
- Class B
- Class C
- Class D
- Class A (Correct answer)
Correct answer: Class A
Class A airspace requires all operations to be conducted under IFR with a filed flight plan and ATC clearance.
