Class Golf Airspace


Airspace Dimensions
Figure 1: General Airspace Overview

Airspace Dimensions:

  • 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

Airspace Depiction:

  • Class G airspace is not depicted on any chart

Air Traffic Control Facility:

  • None

VFR Visibility Requirements:

  • In accordance with FAR 91.155:



Flight Visibility

Distance from Clouds

1,200' or less above the surface (regardless of MSL altitude)

Day: 1 SM

Clear of clouds

Night: 3 SM

500' Below

1,000' Above

2,000' Horizontal

More than 1,200' above the surface, but less than 10,000' MSL

Day: 1 SM

Night: 3 SM

500' Below

1,000' Above

2,000' Horizontal

More than 1,200' above the surface and at or above 10,000' MSL

Day and Night: 5 SM

1,000' Below

1,000' Above

1 SM Horizontal

Entry Requirements:

  • None


  • Student pilot certificate

Aircraft Separation:

  • No formal separation services are provided
  • The pilot is responsibility to see and avoid other aircraft


  • 250 knots below 10,000' MSL


  • Except when associated with a temporary control tower, ATC does not have responsibility for or authority over aircraft in Class G airspace; however, most regulations affecting pilots and aircraft still apply
  • FAR 91.177 includes the IFR requirement to remain at least 1,000' (2,000' in mountainous terrain) above the highest obstacle within a horizontal distance of 4 NM from course to be flown
  • IFR Altitudes (below 18,000'):
    • 0 to 179 degrees: Odd thousands MSL (3,000', 5000', etc.)
    • 180 to 359 degrees: Even thousands MSL (2,000', 4000', etc.)
  • When approaching to land at an airport without an operating control tower in Class G airspace:
    • Each pilot of an airplane must make all turns of that airplane to the left unless the airport displays approved light signals or visual markings indicating that turns should be made to the right, in which case the pilot must make all turns to the right
    • Each pilot of a helicopter or a powered parachute must avoid the flow of fixed-wing aircraft
  • Except when necessary for training or certification, the pilot in command of a civil turbojet-powered aircraft must use, as a final flap setting, the minimum certificated landing flap setting set forth in the approved performance information in the Airplane Flight Manual for the applicable conditions
    • Each pilot in command has the final authority and responsibility for the safe operation of the pilot's airplane, and may use a different flap setting for that airplane if the pilot determines that it is necessary in the interest of safety
  • Unless otherwise authorized or required by ATC, no person may operate an aircraft to, from, through, or on an airport having an operational control tower unless two-way radio communications are maintained between that aircraft and the control tower
  • Communications must be established prior to 4 NM from the airport, up to and including 2,500' AGL
    • If the aircraft radio fails in flight, the pilot in command may operate that aircraft and land if weather conditions are at or above basic VFR weather minimums, visual contact with the tower is maintained, and a clearance to land is received
    • If the aircraft radio fails while in flight under IFR, the pilot must comply with IFR two-way radio communications failure procedures


  • FAR 91.126 regulates operations within Class G airspace
