Operating at an airport in Class G airspace14 CFR 91.126 Operating on or in the vicinity of an airport in Class G airspace
When approaching to land at a Class G airport without an operating control tower, airplanes make all turns to the left unless approved light signals or visual markings show right turns. If the airport has an operational control tower, you must have two-way radio communications with it, established prior to 4 nautical miles from the airport, up to and including 2,500 feet AGL.

At a glance
- The section applies on or in the vicinity of an airport in Class G airspace, unless otherwise authorized or required (a).
- Powered fixed-wing aircraft approaching to land at an airport without an operating tower: all turns to the left, unless approved light signals or visual markings indicate right turns (b)(1).
- Any other powered aircraft must avoid the flow of the fixed-wing traffic (b)(2).
- At an airport with an operational control tower: two-way radio communications with the tower, established prior to 4 nautical miles from the airport, up to and including 2,500 feet AGL, unless ATC authorizes or requires otherwise (d).
- Radio failure in flight: you may operate and land if the weather is at or above basic VFR weather minimums, you keep visual contact with the tower and you receive a clearance to land (d).
In plain English
Section 91.126 covers flying on or near an airport in Class G airspace. Paragraph (b) covers the traffic pattern at airports without an operating control tower. When approaching to land, a pilot of a powered fixed-wing aircraft makes all turns to the left. The exception is an airport that displays approved light signals or visual markings indicating right turns, in which case all turns are to the right (b)(1). Pilots of other powered aircraft, such as helicopters, must avoid the flow of that fixed-wing traffic (b)(2).
Paragraph (d) applies when the airport does have an operational control tower. You may not operate to, from, through or on that airport unless two-way radio communications are maintained with the tower, and they must be established prior to 4 nautical miles from the airport, up to and including 2,500 feet AGL, unless ATC authorizes or requires otherwise.
If the radio fails in flight, the pilot in command may still operate and land if the weather is at or above basic VFR weather minimums (91.155), visual contact with the tower is maintained, and a clearance to land is received. Light gun signals are covered in 91.125. If the radio fails while flying under IFR, the pilot must follow 91.185 instead.
Paragraph (c) is about civil turbojet-powered aircraft, which use as a final flap setting the minimum certificated landing flap setting in the approved performance information in the Airplane Flight Manual, except when necessary for training or certification, with the pilot in command keeping final authority to use a different setting for safety.
Common mistakes
- Flying right traffic by default. Right turns are required only when the airport displays approved light signals or visual markings indicating them (b)(1).
- Skipping the tower call because the airport is in Class G. If the airport has an operational control tower, (d) requires two-way radio communications with it.
- Calling the tower too late. Communications must be established prior to 4 nautical miles from the airport, up to and including 2,500 feet AGL (d).
The official text
14 CFR 91.126 as published on the eCFR, current as of October 14, 2026.
(a) General. Unless otherwise authorized or required, each person operating an aircraft on or in the vicinity of an airport in a Class G airspace area must comply with the requirements of this section.
(b) Direction of turns. When approaching to land at an airport without an operating control tower in Class G airspace—
(1) Each pilot of a powered fixed-wing aircraft must make all turns 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; and
(2) Each pilot of any other powered aircraft must avoid the flow of the aircraft specified in paragraph (b)(1) of this section.
(c) Flap settings. 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. However, 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.
(d) Communications with control towers. 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 nautical miles from the airport, up to and including 2,500 feet AGL. However, 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 § 91.185.

Sport Pilot
Unless otherwise indicated, the standard traffic pattern at a non-towered airport uses:
- A. left turns.
- B. right turns.
- C. left turns for airplanes and right turns for helicopters.
- D. whichever direction the pilot prefers.
Show answer
A. left turns. Left traffic is standard. Right traffic is charted and shown by a segmented circle with traffic pattern indicators, and it is noted in the Chart Supplement. Check before you arrive, because opposing patterns are a classic mid-air setup.

At an airport without an operating control tower, the standard traffic pattern uses
- A. left turns, unless right traffic is indicated.
- B. right turns at all such airports.
- C. either direction at the pilot's discretion.
- D. straight-in approaches only.
Show answer
A. left turns, unless right traffic is indicated. The standard pattern is left turns. Right traffic is used where indicated by the segmented circle, chart notes, or airport signage.
More Private Pilot practice →Private Helicopter
When operating at an airport without an operating control tower, helicopter pilots must:
- A. avoid the flow of fixed-wing aircraft.
- B. enter the standard left-hand fixed-wing traffic pattern.
- C. always land on the active runway.
- D. circle overhead at pattern altitude before landing.
Show answer
A. avoid the flow of fixed-wing aircraft. The rule is not "join the pattern" but "avoid the flow": 91.126(b)(2) requires powered aircraft other than fixed-wing to avoid the flow of fixed-wing traffic. Helicopters typically fly a lower pattern, around 500 feet AGL and closer to the runway, sometimes on the opposite side of the runway, and landings not to the runway must also avoid the fixed-wing flow.

Questions pilots ask
Do you have to fly left traffic at an uncontrolled airport?
In Class G airspace at an airport without an operating control tower, a powered fixed-wing aircraft approaching to land makes all turns to the left, unless the airport displays approved light signals or visual markings indicating right turns (91.126(b)(1)).
When do I have to contact the tower at a towered airport in Class G airspace?
Two-way radio communications with the tower must be established prior to 4 nautical miles from the airport, up to and including 2,500 feet AGL, and maintained while operating to, from, through or on the airport, unless ATC authorizes or requires otherwise (91.126(d)).
What if my radio fails near a towered airport in Class G airspace?
Under VFR, the pilot in command may operate and land if weather is at or above basic VFR weather minimums, visual contact with the tower is maintained and a clearance to land is received. Under IFR, follow 91.185 (91.126(d)).
