What is Class G airspace used for?

Class G airspace (uncontrolled) is that portion of airspace that has not been designated as Class A, Class B, Class C, Class D, or Class E airspace. Rules governing VFR flight have been adopted to assist the pilot in meeting the responsibility to see and avoid other aircraft.

Class G Requirements:
  • Uncontrolled, you do not need to contact ATC to enter or land in Class G airspace.
  • There are no specific equipment requirements.
  • Basic VFR minimums apply, which are 1sm visibility and Clear of Clouds (don't fly your airplane into a cloud or let it touch a cloud)

On a map, Class G's ceiling is the floor of Class E airspace. And, it's always exclusive. For example, if Class E starts at 700 feet AGL, Class G goes up to, but doesn't include, 700 feet AGL. Class G airspace is most easily found on a sectional map when a fading, thick blue line appears.

Class G airspace is the only uncontrolled airspace out there in the United States. Thus, both IFR and VFR traffic is also uncontrolled here. To find out Class G airspace, note that it exists where the other five airspace classes, i.e., Class A, B, C, D, or E, don't.

Permission is not required. Think of G as in “Ground” (It's the airspace that covers most of the ground in the U.S.) Class G airspace is uncontrolled airspace that has not been designated as Class A, B, C, D, or E. The only requirements are to have 1 mile of visibility and to stay clear of clouds.

CBO operations and events occurring at 400 feet AGL and below in Class G airspace do not require FAA review, approval or authorization. CBO's intending to conduct events in Class G airspace that may exceed 400 feet AGL must contact the FAA for further information.

MORE DETAILS

Class G airspace does not have the ATC control or support to fly on an IFR flight plan. You may, however, takeoff and land at a Class G airport. If you enter or fly through a Class G airspace, ATC control and support is terminated until you re-enter controlled airspace or close your flight plan.

Classes A through E are all types of controlled airspace. This is where air traffic control has various levels of jurisdiction. Class G is considered “uncontrolled.” In Class G airspace, pilots are solely responsible for their own navigation and separation from traffic, terrain, and obstructions.

Class C or D airspace (at or below 2,500 feet agl within 4 nm of the primary airport) — 200 kias (unless a higher speed is specifically approved by ATC) Class E or G airport traffic pattern — 200 kias (recommended)

MORE DETAILS

A pilot must maintain a vertical distance of 1,000ft above, 500ft below, and 2,000ft horizontally in Class G airspace at these altitudes. When operating at and below 1,200ft AGL in Class G airspace, a pilot must remain clear of clouds during the day and have a minimum forward flight visibility of 1sm.

Class G airspace within the United States extends up to 14,500' Mean Sea Level (MSL) At and above this altitude is Class E, excluding the airspace less than 1500' above the terrain and certain special use airspace areas.

MORE DETAILS

Class G airspace extends from the surface to the base of the overlying Class E airspace. Although ATC has no authority or responsibility to control air traffic, pilots should remember there are visual flight rules (VFR) minimums that apply to Class G airspace.

There are two categories of airspace or airspace areas: Regulatory (Class A, B, C, D, and E airspace areas, restricted and prohibited areas). Nonregulatory (military operations areas [MOA], warning areas, alert areas, controlled firing areas [CFA], and national security areas [NSA]).

As described in 14 CFR 91.225, ADS-B Out performance is required to operate in: Class A, B, and C airspace. Above the ceiling and within the lateral boundaries of a Class B or Class C airspace area upward to 10,000 feet MSL .

The most common example of needing to use instruments is flying through clouds or IMC conditions. IMC, or Instrument Meteorological conditions, is weather that require the use of instruments, typically cloudy or low visibility. That means pilots using IFR clearances can fly without ever seeing the ground.

Traditionally, an airliner is divided into, from the fore to aft, first, business, and economy classes, sometimes referred to as cabins. In recent years, some airlines have added a premium economy class as an intermediate class between economy and business classes.

Remote ID also helps the FAA, law enforcement, and other federal agencies locate the control station when a drone appears to be flying in an unsafe manner or where it is not allowed to fly.
