Which class is associated with terminal control areas around large airports, typically near 10 NM radius up to 12,500 feet?

• A. Class D
• B. Class E
• C. Class G
• D. Class C

Answer: (D)

Terminal control areas around large airports are Class C airspace. This type of airspace is designed to provide ATC radar services and orderly traffic flow for busy airports. It typically forms a roughly 10 nautical mile radius around the airport and extends upward to a ceiling around 12,500 feet MSL, though exact limits can vary by location. Within this area, pilots must establish two-way radio communication with ATC before entering and usually must have a transponder with altitude reporting (Mode C) enabled. The inner core and outer shelf structure helps manage traffic entering and leaving the airport while keeping other aircraft separated. This combination of mandatory communication, radar services, and the 10 NM/ceiling setup distinguishes Class C from other airspace classes.
