Class G airspace is also known as what type of airspace?

1. Controlled airspace

2. Uncontrolled airspace

3. Special use airspace

4. Aeronautical airspace

The correct answer is: Uncontrolled airspace

Class G airspace is defined as uncontrolled airspace. This type of airspace generally exists at lower altitudes where air traffic control (ATC) does not provide any services or traffic advisories. Pilots operating in Class G airspace are responsible for their own navigation and separation from other aircraft since it does not have the same regulatory oversight as controlled airspace. Understanding the characteristics of Class G airspace is essential for pilots, as it influences flight planning, communication procedures, and altitude restrictions. For instance, in Class G airspace, visibility and cloud clearance requirements can differ from those found in controlled airspace, allowing for more flexibility, particularly during visual flight rules (VFR) operations. In contrast, controlled airspace refers to areas where ATC has jurisdiction and provides services to manage flight operations, which is not the case in Class G airspace. Special use airspace is designated for specific activities, such as military operations, and aeronautical airspace is a broader term that doesn't specifically categorize the control status of the airspace. Therefore, recognizing Class G as uncontrolled airspace is crucial for safe and effective flight operations.
