What airspace is you likely to find around a significant city?

Class C airspace is commonly found around significant cities primarily due to the increased volume of air traffic that these urban areas typically generate. This type of airspace is designed to provide a safe and orderly flow of both commercial and general aviation traffic. Class C airspace usually extends from the surface to a specific altitude, often up to 4,000 feet above the airport elevation, creating a controlled environment for aircraft operating in and out of busy airports.

In Class C airspace, aircraft must establish two-way communication with the air traffic control (ATC) tower before entering, which helps to manage the high density of air traffic. This requirement enhances safety by ensuring that pilots receive relevant traffic advisories and are in communication with control personnel as they operate in a busy airspace.

While other classes of airspace, such as Class A and Class D, may also be present in certain areas, they are less commonly associated with high-traffic urban environments. Class D airspace typically surrounds smaller airports with an operating control tower, while Class A is found at higher altitudes and is reserved for IFR (Instrument Flight Rules) operations. Class G airspace, conversely, is uncontrolled airspace, often found in rural areas, making it less likely to be situated
