Class G is uncontrolled airspace: everything not designated Class A, B, C, D or E. It runs from the surface up to the floor of the Class E above it, usually 700 or 1,200 feet above the ground and in remote areas as high as 14,500 feet MSL. By day, within 1,200 feet of the ground, VFR needs only 1 statute mile visibility and clear of clouds.
Those are the loosest VFR minimums in the system, and they are why Class G gets more questions on the knowledge test than its size deserves. Around Los Angeles you rarely fly in it for long. You meet it as a thin layer near the ground at some of the airports beyond the basin, and in the rules for flying the traffic pattern at a field with no tower. Here is what Class G is, where it is, the full weather table, IFR without a clearance, and how to fly into a non-towered airport properly.

What Class G (Uncontrolled) Airspace Is
AIM 3-3-1 defines Class G as airspace not designated Class A, B, C, D or E. It is the remainder. The Pilot's Handbook of Aeronautical Knowledge adds the practical part: ATC has no authority or responsibility to control air traffic in it.
Uncontrolled does not mean unregulated. Part 91 still applies in full. You still need the VFR weather minimums in 14 CFR 91.155 and you still give way under the right-of-way rules. AIM 3-3-2 adds that VFR in Class G rests on your duty to see and avoid other aircraft. What goes away is the controller. Nobody issues clearances, nobody separates IFR traffic, and in most Class G you will not hear anyone unless they choose to talk.
Class G is also not the same thing as a non-towered airport. Plenty of airports without a tower sit inside a Class E surface area, controlled to the ground. We come back to that below, because it changes which weather rules apply in the pattern.
Where It Exists: Surface To 700 Or 1,200 AGL, And Up To 14,500 MSL
The Pilot's Handbook puts it in one line: Class G runs from the surface to the base of the overlying Class E. So to find Class G, find the Class E floor.
- Under a 700-foot floor. Around airports with instrument approaches, Class E usually begins 700 feet above the ground, shown on the sectional by a soft magenta band. Below that, from the surface to 699 feet AGL, the airspace is Class G unless a surface area or a tower's airspace reaches the ground.
- Under a 1,200-foot floor. Across most of the country, Class E begins 1,200 feet above the ground, so Class G is the layer below it.
- Up to 14,500 feet MSL. In remote areas where no lower Class E is designated, Class G runs all the way up to the 14,500-foot Class E layer. The sectional marks the edge of such areas with a soft blue band.
One detail matters for the test. 14 CFR 91.155(e) says an aircraft flying at the base altitude of a Class E area is treated as being in the airspace directly below it. Fly exactly at 700 feet AGL under a 700-foot floor and you are in Class G for weather purposes.
Equipment rules do not care about the class. Van Nuys sits inside the 30-nautical-mile Mode C veil around LAX, where a transponder with altitude reporting and ADS-B Out are required from the surface to 10,000 feet MSL, Class G or not. The 250-knot limit below 10,000 feet in 91.117(a) applies here too.
VFR Weather Minimums In Class G (Day, Night, Above 1,200 AGL)
Class G has more rows in the 91.155 table than any other class. The rules change with height above the ground, with day and night, and again at 10,000 feet MSL. These are the airplane rows; helicopters have their own.
| Altitude | Day | Night |
|---|---|---|
| 1,200 feet AGL or less | 1 statute mile, clear of clouds | 3 statute miles; 500 below, 1,000 above, 2,000 horizontal |
| Above 1,200 feet AGL, below 10,000 feet MSL | 1 statute mile; 500 below, 1,000 above, 2,000 horizontal | 3 statute miles; 500 below, 1,000 above, 2,000 horizontal |
| Above 1,200 feet AGL, at or above 10,000 feet MSL | 5 statute miles; 1,000 below, 1,000 above, 1 statute mile horizontal | 5 statute miles; 1,000 below, 1,000 above, 1 statute mile horizontal |
There is one exception, in 91.155(b)(2). At night, in Class G below 1,200 feet AGL, an airplane may fly clear of clouds in the pattern within half a mile of the runway. Visibility may then be less than 3 miles but must be at least 1 mile. It exists so a pilot can stay in the pattern at a small field on a hazy night.
Why A Student Pilot Cannot Use The One-Mile Rule
Look at the day row again: 1 mile and clear of clouds. Legal for a private pilot, and the reason Class G is where VFR pilots get into trouble, because a mile of visibility at 100 knots is about half a minute of warning. A student pilot cannot use it at all. 14 CFR 61.89(a)(6) bars a student from flying with less than 3 statute miles visibility by day or 5 at night, and 61.89(a)(7) bars any flight without visual reference to the surface. Your solo endorsement may set limits tighter still. Our what is VFR guide sets the Class G rows beside every other class.
IFR In Class G: Legal But Unusual
The clearance rule, 14 CFR 91.173, covers controlled airspace only. It bars IFR flight there without a filed flight plan and an ATC clearance. Class G is not controlled, so an instrument-rated pilot may legally fly IFR in it without either one.
It is rare for a reason. Class G is usually a thin layer near the ground. The IFR minimum altitude rule in 91.177 requires 1,000 feet above the highest obstacle within 4 nautical miles of the course, or 2,000 feet in designated mountainous terrain. In most places that puts you above the Class G and into controlled airspace, where the clearance is required again. AIM 3-3-3 gives the IFR cruising altitudes for Class G: odd thousands on a magnetic course of 0 to 179 degrees, even thousands from 180 to 359.
What you will see in practice is an IFR departure from a small field in uncontrolled airspace, where the pilot gets the clearance on the ground and climbs into the Class E above. No controller separates you in the Class G portion, so you are on your own for traffic until you are in the system. The instrument rating covers how those departures are briefed and flown.
Non-Towered Airport Operations: CTAF, Pattern Entry, Self-Announcing
The FAA's guidance for airports without an operating tower is Advisory Circular 90-66C, dated June 2023, backed by 14 CFR 91.126 and AIM 4-1-9. It applies whether the field sits in Class G or in a Class E surface area. The core of it:
- Under 91.126(b), airplanes make all pattern turns to the left unless the airport shows approved light signals or markings for right turns. Right traffic is marked "RP" on the sectional and listed in the Chart Supplement.
- AC 90-66C recommends a pattern altitude of 1,000 feet above the airport for propeller airplanes unless the airport publishes something else, and at least 1,500 feet for large and turbine aircraft.
- Join the downwind at a 45-degree angle abeam the middle of the runway, already at pattern altitude. Do not descend into the pattern.
- On departure, fly straight past the end of the runway. Turn crosswind only beyond the departure end and within 300 feet of pattern altitude. Leave straight out or with a 45-degree turn after reaching pattern altitude.
- Straight-in approaches are discouraged. A straight-in airplane has no priority over traffic already in the pattern.
- The 91.113 right-of-way rules apply throughout. The lower aircraft on final has the right-of-way but may not cut in front of another airplane on final.
Talking On The CTAF
The common traffic advisory frequency, or CTAF, is the frequency everyone at a non-towered field shares. It may be a UNICOM, a MULTICOM or a tower frequency used after hours. AIM 4-1-9 and AC 90-66C ask you to monitor it from 10 miles out and to announce yourself: 10 miles out, entering downwind, base and final, and leaving the runway. Departing, announce before you taxi and before you taxi onto the runway.
Say the airport name at the start and end of every call, use runway numbers rather than "the active", and never say "any traffic in the area, please advise". The FAA calls that phrase unrecognized and says it should not be used under any condition. Where a field has no tower, no flight service station and no UNICOM, the AIM says to self-announce on MULTICOM, 122.9. Full scripts are on our radio calls for student pilots page, and the pattern itself is on traffic pattern, landings and go-arounds.
Class G Near Los Angeles: Where You Actually Find It
Not much of it, and not where students expect. Our airspace classes overview makes the point that Class E floors sit low almost everywhere in the Los Angeles basin, so the Class G under them is a few hundred feet thick at most. The same page notes that you find more of it heading north over the Antelope Valley. Van Nuys itself is never Class G: Class D while the tower is open, 6:00 AM to 10:45 PM, and a Class E surface area the rest of the time.
Where a Van Nuys student does meet uncontrolled airspace is the first non-towered destinations. From our list of cross-country destinations from Van Nuys, four have no tower:
- Santa Paula (KSZP), about 30 nautical miles west-north-west, with a 2,665 by 60-foot runway.
- Catalina (KAVX), about 48 nautical miles south, 1,602 feet up on the island.
- Big Bear City (L35), about 81 nautical miles east, at 6,752 feet.
- Paso Robles (KPRB), about 137 nautical miles north-west.
Non-towered does not mean Class G. Before each one, look at the sectional around the field. A dashed magenta ring means a Class E surface area, and the 3-mile, 1,000-foot rules apply to the pattern. No ring, with a magenta band around the field, means Class G from the surface to 700 feet. A 1,000-foot pattern then sits partly in Class G and partly in Class E, with different weather minimums above and below 700 feet. Read the airspace from the current chart every time; do not rely on memory or on this page.
Each of these fields teaches something. Santa Paula is short-field practice with terrain on both sides; our short-field and soft-field landings guide covers the technique. Catalina is an over-water leg and a runway on a plateau, covered on flying to Catalina Island. Big Bear is density altitude, which is why it anchors our mountain flying checkout.
Class G Vs Class E
| Item | Class G | Class E |
|---|---|---|
| Controlled? | No | Yes |
| IFR clearance | Not required | Required, with a flight plan |
| VFR radio or clearance | None | None, except near an operating tower |
| Day, low altitude | 1 statute mile, clear of clouds | 3 statute miles; 500 below, 1,000 above, 2,000 horizontal |
| Night, low altitude | 3 statute miles; 500, 1,000, 2,000 (1 mile in the pattern near the runway) | 3 statute miles; 500, 1,000, 2,000 |
| At or above 10,000 feet MSL | 5 statute miles; 1,000, 1,000, 1 mile (above 1,200 AGL) | 5 statute miles; 1,000, 1,000, 1 mile |
| Surface-area rules | None | 1,000-foot ceiling and 3 miles to use a surface-area airport |
The two classes feel the same from the cockpit, because neither asks you to talk to anyone. The difference is entirely the weather, and the controlled side is stricter. Our Class E airspace page covers the other half of the comparison.

Class G Airspace FAQ
What Is Class G Airspace?
Class G is uncontrolled airspace, the airspace not designated as Class A, B, C, D or E. It extends from the surface to the floor of the overlying Class E. ATC does not control traffic in it, but the VFR weather minimums and the rest of Part 91 still apply.
What Are The VFR Weather Minimums In Class G Airspace?
At or below 1,200 feet AGL, 1 statute mile and clear of clouds by day, and 3 miles with 500 feet below, 1,000 above and 2,000 horizontal at night. Above 1,200 feet AGL it is 1 mile by day and 3 at night with the same cloud distances, and 5 miles with 1,000, 1,000 and 1 mile at or above 10,000 feet MSL.
Can You Fly IFR In Class G Airspace?
Yes. 14 CFR 91.173 requires a flight plan and clearance only in controlled airspace, so an instrument-rated pilot may fly IFR in Class G without one. The 91.177 minimum altitude of 1,000 feet above obstacles, or 2,000 in mountainous terrain, usually puts the flight into controlled airspace anyway.
Is Every Non-Towered Airport In Class G Airspace?
No. Many non-towered airports with instrument approaches have a Class E surface area, controlled to the ground, shown by a dashed magenta line on the sectional. Van Nuys itself becomes a Class E surface area, not Class G, when its tower closes at 10:45 PM.
What Is The Traffic Pattern Altitude At A Non-Towered Airport?
AC 90-66C recommends 1,000 feet above the airport for propeller airplanes unless the airport publishes another altitude, and at least 1,500 feet for large and turbine aircraft. Turns are to the left unless the Chart Supplement or the sectional shows right traffic.
Is There Class G Airspace Near Los Angeles?
Very little. Class E floors sit low across the basin, so any Class G is a thin layer near the ground, with more of it north over the Antelope Valley. Check the sectional around each non-towered destination, such as Santa Paula or Big Bear, before you fly the pattern there.
Can A Student Pilot Use The Class G One-Mile Minimum?
No. 14 CFR 61.89(a)(6) bars student pilots from flying with less than 3 statute miles visibility by day or 5 at night, whatever the airspace allows. A solo endorsement can set tighter limits still.
Fly A Non-Towered Pattern With An Instructor
Your first landing at a field with no tower should be dual, with an instructor beside you on the CTAF. It starts with an hour at Van Nuys: a 60-minute discovery flight is $229 and logs as dual instruction, and the two-hour beginner flying lesson is $349 in a Cessna 162 or Piper Warrior. The non-towered cross-countries come inside our private pilot course, from $10,400 with $2,500 down. Want the plan first? Book a free consultation.
