Final answer:
Class C airspace typically extends out from the center of the primary airport for 20 nautical miles. Class C airspace typically has an outer ring that extends up to 10 nautical miles from the center of the primary airport.
Step-by-step explanation:
Class C airspace is a type of controlled airspace used for handling higher levels of air traffic close to busy airports. The charted outer ring of Class C airspace typically extends out from the center of the primary airport for 20 nautical miles. This means that aircraft operating within this outer ring are subject to communication requirements and air traffic control services.
Class C airspace typically has an outer ring that extends up to 10 nautical miles from the center of the primary airport. The outer ring of Class C airspace around a primary airport typically extends up to 10 nautical miles from the center of that airport. Specifically, this type of airspace usually consists of a 5 nautical mile radius core surface area that extends from the surface to 4,000 feet above the airport elevation, and a 10 nautical mile radius shelf area that extends from 1,200 feet to 4,000 feet above the airport elevation.
Class C airspace is a controlled airspace designation established by the Federal Aviation Administration (FAA) in the United States. The charted outer ring of Class C airspace typically extends out from the center of the primary airport for a distance of 20 nautical miles. This outer ring is designed to provide additional controlled airspace beyond the primary Class C airspace to accommodate arriving and departing traffic. Within this outer ring, aircraft may still be subject to specific communication and transponder requirements, even though they are not directly under the jurisdiction of the Class C airspace controller.
The purpose of extending the outer ring is to ensure that air traffic controllers have the necessary control and coordination to manage the flow of traffic in and out of the primary airport. Pilots entering this outer ring are often required to establish communication with the air traffic control facility, providing essential information about their aircraft and intentions. This communication helps controllers maintain safe and efficient separation between aircraft operating within and outside the primary Class C airspace. The specific dimensions and altitudes of Class C airspace can vary depending on the airport and local airspace considerations, and pilots should consult aviation charts and relevant publications for accurate and up-to-date information.
