PSTAR Airspace Classification and Requirements 1 — Questions and Answers
Question 1: What equipment is required to operate in Class B airspace?
- Only a radio
- Two-way radio, transponder with Mode C, and ATC clearance (Correct answer)
- Only a transponder
- No special equipment required
Correct answer: Two-way radio, transponder with Mode C, and ATC clearance
Class B airspace requires a two-way radio, an ATC clearance to enter, and a transponder with altitude encoding (Mode C).
Question 2: What are the VFR weather minimums in Class G airspace below 1,200 feet AGL during the day?
- 3 miles visibility, 500-1000-2000 cloud clearances
- 1 mile visibility, clear of clouds (Correct answer)
- 5 miles visibility, 1000-1000-2000
- 3 miles visibility, clear of clouds
Correct answer: 1 mile visibility, clear of clouds
In Class G airspace below 1,200 feet AGL during the day, the minimums are 1 mile visibility and clear of clouds.
Question 3: Class A airspace in the US begins at what altitude?
- 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 begins at 18,000 feet MSL and extends to FL600, requiring IFR flight and ATC clearance.
Question 4: What are the standard VFR weather minimums in Class E airspace above 10,000 feet MSL?
- 3 miles, 500-1000-2000 clearance
- 5 miles, 1000-1000-2000 clearance (Correct answer)
- 3 miles, clear of clouds
- 1 mile, clear of clouds
Correct answer: 5 miles, 1000-1000-2000 clearance
Above 10,000 feet MSL in Class E airspace, VFR requires 5 miles visibility and 1,000 feet above, 1,000 feet below, 1 mile horizontally from clouds.
Question 5: What is required to operate within Class C airspace?
- ATC clearance, Mode C transponder, and two-way radio
- Two-way radio communication established and Mode C transponder (Correct answer)
- Only a Mode C transponder
- Only ATC clearance
Correct answer: Two-way radio communication established and Mode C transponder
Class C requires two-way radio communication with approach control and a Mode C transponder — no explicit clearance needed, just communication.
Question 6: What type of airspace surrounds most major US airline hub airports?
- Class C
- Class D
- Class B (Correct answer)
- Class E
Correct answer: Class B
Class B airspace surrounds the nation's busiest commercial airports, designed as an upside-down wedding cake of controlled airspace.
