What is the maximum airspeed permitted in Class C airspace?

In Class C airspace, the maximum permitted airspeed is 200 knots indicated airspeed (KIAS). This limitation is in place to ensure that aircraft operations within the vicinity of busy airports remain safe, particularly because Class C airspace surrounds airports with a significant amount of traffic.

When flying in this airspace, pilots are often required to be in communication with air traffic control, and maintaining a lower airspeed helps to facilitate safe spacing between aircraft, reduces the risk of wake turbulence, and ensures that flight operations can be managed more effectively. Class C airspace generally extends from the surface up to 4,000 feet above the airport elevation, and the reduced maximum airspeed restriction contributes to safe and organized traffic flow within that environment, especially as aircraft are preparing to land or take off.

The other options exceed this maximum limit and could lead to safety concerns or violations of air traffic control directives.
