What class and dimensions of airspace does the home field have?

• A. B, Surface to 4200 MSL 5 mi radius
• B. C, Surface to 4200 MSL 5 mi radius, 10 mi radius 1400 MSL to 4200 MSL
• C. D, Surface to 6000 MSL 5 mi radius
• D. A, Surface to 5000 MSL 10 mi radius

Answer: (B)

The home field being classified as Class C airspace indicates that it is an area where air traffic control requires aircraft to establish communication with them prior to entering. The dimensions provided in the correct choice suggest that the primary area extends from the surface up to 4,200 feet mean sea level (MSL) within a 5 nautical mile radius from the airport. Additionally, there is an outer shelf extending from 1,400 feet to 4,200 feet MSL, reaching out to 10 nautical miles, which is characteristic of Class C airspace.

This classification and dimensional setup are designed to provide air traffic services to the increased volume of aircraft typical in areas surrounding airports that have significant operational activity. Understanding these complexities is crucial for pilots to ensure safe navigation and compliance with air traffic regulations when approaching or departing from such airports.
