Chapter 8 — Airspace Classification and Requirements

Uncontrolled Airspace: Class G Airspace

Uncontrolled or Class G airspace is the portion of the airspace that has not been designated as Class A, B, C, D, or E. It is therefore designated uncontrolled airspace. Class G airspace extends from the surface to the base of the overlying Class E airspace. Although air traffic control has no authority or responsibility to control air traffic in Class G airspace, you should remember there are visual flight rule (VFR) minimums (visibility and cloud clearance) which apply to Class G airspace.

Special Use Airspace

Special use airspace exists where activities must be confined because of their nature. In special use airspace, limitations may be placed on aircraft that are not a part of the activities. Special use airspace usually consists of:

• Prohibited Areas.
• Restricted Areas.
• Warning Areas.
• Military Operation Areas.
• Alert Areas.
• Controlled Firing Areas.

It is important you review the current sectional chart for the area you will be flying in to make sure you avoid operating in special use airspace without proper training and authority. [Figure 8-4]

Prohibited Areas

Prohibited areas are established for security or other reasons associated with the national welfare. Prohibited areas are published in the Federal Register and are depicted on aeronautical charts.

Restricted Areas

Restricted areas denote the existence of unusual, often invisible hazards to aircraft such as artillery firing, aerial gunnery, or guided missiles. An aircraft may not enter a restricted area unless permission has been obtained from the controlling agency. Restricted areas are depicted on aeronautical charts and are published in the Federal Register. Restricted areas may have altitude limitations and hours of operation. Aircraft operations are not restricted if the restricted area is not active.

Warning Areas

Warning areas consist of airspace which may contain hazards to nonparticipating aircraft in international airspace. The activities may be much the same as those for a restricted area. Warning areas are established beyond the 3-mile limit. Warning areas are depicted on aeronautical charts.
