Airspace PNG Images Transparent Background

Airspace refers to the portion of the earth’s atmosphere controlled by a sovereign state, where commercial and non-commercial aircraft operate. This airspace is divided into different classes, each having different restrictions and requirements. The classification of airspace is essential in ensuring safe operation, coordination, and separation of aircraft movements to avoid collision.

Types of Airspace

There are six different types of airspace classes, namely:

Class A airspace

It is the highest controlled airspace in the United States, with aircraft operating under Instrument Flight Rules (IFR) only. It starts at 18,000 feet above sea level and extends up to flight level 600. Controllers provide continuous surveillance and separation services for all aircraft within this airspace.

Class B airspace

This airspace is typically found around the busiest airports in the United States and requires additional clearance to operate. Controllers provide separation services for all users, including aircraft flying under Visual Flight Rules (VFR). Typically, a pilot must contact Control Tower to receive clearance to enter Class B airspace.

Class C airspace

This airspace typically surrounds airports with high levels of commercial and private traffic. It extends up to 1200 feet above ground level within a five-mile radius of the airport. Air Traffic Control provides separation services for aircraft operating under both IFR and VFR rules.

Class D airspace

This airspace typically surrounds smaller airports with less traffic than Class C airspace. It extends up to 2500 feet above ground level within a five-mile radius of the airport. Pilots are required to establish communication with the control tower to receive clearance before entering Class D airspace.

Class E airspace

This airspace is the most common type of airspace in the United States. It extends from the surface to either 700 or 1200 feet above ground level, depending on the location of the airspace. This airspace is typically uncontrolled, meaning no air traffic control services are provided, and pilots use their discretion to avoid other aircraft.

Class G airspace

It is the uncontrolled airspace that extends from the surface up to 700 or 1200 feet depending on location. Pilots are not required to establish communication or receive clearance before operating in Class G airspace.

Airspace is an essential element in regulating air traffic worldwide, with different classes serving varying purposes. The classification helps ensure that aircraft operate safely and efficiently while minimizing the risk of collision and injury. Pilots must understand the classifications to operate safely within the airspace and ensure they have the required clearance to enter.
