What is the altitude limit for Class C airspace?

• A. 2,500 ft above airport elevation
• B. 4,000 ft above airport elevation
• C. 10,000 ft above airport elevation
• D. 14,500 ft MSL

Answer: (B)

The altitude limit for Class C airspace extends up to 4,000 feet above the airport elevation, which is why this answer is accurate. Class C airspace typically starts from the surface and extends upward to a specified limit, which in this case is established at 4,000 feet AGL (above ground level) within the designated region around the airport. This range allows for a controlled airspace environment where air traffic control can manage both arriving and departing aircraft effectively. The lower limit and vertical extent help ensure separation from surrounding airspace while accommodating aircraft traffic, particularly in areas with significant commercial or general aviation activity. Consequently, the 4,000-foot ceiling supports safe operations while still permitting access for other classes of airspace that may be at higher altitudes.
