Traffic pattern altitudes and proceduresAIM 4-3-3 Traffic Patterns
The AIM recommends entering the traffic pattern at 1,000 feet AGL in a propeller-driven aircraft and at not less than 1,500 feet AGL or 500 feet above the established pattern altitude in a large or turbine-powered aircraft, unless the Chart Supplement publishes another altitude. Unless otherwise indicated, pattern turns are to the left, and right patterns are marked "RP" on VFR charts.

At a glance
- Propeller-driven aircraft: enter the pattern at 1,000 feet AGL (AIM 4-3-3a1).
- Large and turbine-powered aircraft: not less than 1,500 feet AGL or 500 feet above the established pattern altitude (AIM 4-3-3a2).
- Helicopters: a similar pattern at a lower altitude (500 AGL) and closer to the runway (AIM 4-3-3a3).
- Use a different altitude if the Chart Supplement publishes one or if the cloud clearances of 14 CFR 91.155 require it (AIM 4-3-3a).
- Unless otherwise indicated, turns in the pattern are made to the left, except for helicopters as applicable (AIM 4-3-3c).
- Right patterns appear on sectional and VFR terminal area charts as "RP" plus the runway numbers, for example "RP 9, 18, 22R" (AIM 4-3-3d).
In plain English
AIM 4-3-3 is the FAA's guidance on flying the airport traffic pattern. The altitudes in AIM 4-3-3a are recommendations: the AIM says it is recommended that aircraft enter the pattern at 1,000 feet AGL in a propeller-driven aircraft, and at not less than 1,500 feet AGL or 500 feet above the established pattern altitude in a large or turbine-powered aircraft. Those altitudes give way when the Chart Supplement publishes a different pattern altitude, or when the cloud clearance rules of 14 CFR 91.155, which are regulation, require something else. Helicopters may fly a similar pattern at a lower altitude (500 AGL) and closer to the runway, and sometimes on the opposite side from fixed-wing traffic when airspeed requires or for practice autorotations, if local policy permits (AIM 4-3-3a3).
AIM 4-3-3c states that, unless otherwise indicated, all turns in the traffic pattern must be made to the left, except for helicopters as applicable. Where a runway uses right traffic, sectional, aeronautical and VFR terminal area charts show it at public-use and joint-use airports with "RP" and the runway numbers at the bottom of the airport data block (AIM 4-3-3d). An asterisk before RP means special conditions exist and refers you to the Chart Supplement, and right patterns are not shown at airports with full-time control towers (AIM 4-3-3d, Notes 2 and 3). The AIM also says a pilot may vary the size of the pattern to suit the aircraft's performance (AIM 4-3-3b).
The single-runway pattern figure in this paragraph comes with a key. It describes entering in level flight, abeam the midpoint of the runway, at pattern altitude, holding pattern altitude on downwind until abeam the approach end of the landing runway, and completing the turn to final at least 1/4 mile from the runway (key items 1 to 3). After takeoff, continue straight ahead until beyond the departure end of the runway; if staying in the pattern, start the turn to crosswind beyond the departure end within 300 feet of pattern altitude (key items 4 and 5). If leaving the pattern, continue straight out or exit with a 45 degree turn (to the left in a left-hand pattern, to the right in a right-hand pattern) beyond the departure end, after reaching pattern altitude (key item 6).
The AIM encourages pilots to use the standard traffic pattern, and says a pilot who chooses a straight-in approach should not disrupt the flow of arriving and departing traffic, while pilots in the pattern should stay alert for straight-in traffic (AIM 4-3-3d, Note 1). En route pilots should be constantly alert for aircraft in traffic patterns and avoid those areas whenever possible (AIM 4-3-3b). For wind, AIM 4-3-3e points to an example chart of headwind, crosswind and tailwind components and advises using the similar information provided by the aircraft manufacturer.
Common mistakes
- Using 1,000 feet AGL everywhere. The AIM's recommended altitude gives way to a pattern altitude published in the Chart Supplement (AIM 4-3-3a).
- Assuming every runway uses left traffic. Check the chart for "RP" and the Chart Supplement, especially when RP has an asterisk (AIM 4-3-3d).
- Turning crosswind too early. The single-runway figure key says to turn beyond the departure end of the runway, within 300 feet of pattern altitude (key item 5).
- Mixing up AGL and MSL. The AIM's pattern altitudes are given in feet above ground level (AIM 4-3-3a).
The official text
AIM 4-3-3 as published on faa.gov, effective July 9, 2026.
a. It is recommended that aircraft enter the airport traffic pattern at one of the following altitudes listed below. These altitudes should be maintained unless another traffic pattern altitude is published in the Chart Supplement or unless otherwise required by the applicable distance from cloud criteria (14 CFR section 91.155). (See FIG 4-3-2 and FIG 4-3-3):
1. Propeller-driven aircraft enter the traffic pattern at 1,000 feet above ground level (AGL).
2. Large and turbine-powered aircraft enter the traffic pattern at an altitude of not less than 1,500 feet AGL or 500 feet above the established pattern altitude.
3. Helicopters operating in the traffic pattern may fly a pattern similar to the fixed-wing aircraft pattern, but at a lower altitude (500 AGL) and closer to the runway. This pattern may be on the opposite side of the runway from fixed-wing traffic when airspeed requires or for practice power-off landings (autorotation) and if local policy permits. Landings not to the runway must avoid the flow of fixed wing traffic.
b. A pilot may vary the size of the traffic pattern depending on the aircraft's performance characteristics. Pilots of en route aircraft should be constantly alert for aircraft in traffic patterns and avoid these areas whenever possible.
c. Unless otherwise indicated, all turns in the traffic pattern must be made to the left, except for helicopters, as applicable.
d. On Sectional, Aeronautical, and VFR Terminal Area Charts, right traffic patterns are indicated at public-use and joint-use airports with the abbreviation “RP” (for Right Pattern), followed by the appropriate runway number(s) at the bottom of the airport data block.
EXAMPLE-
RP 9, 18, 22R
NOTE-
1. Pilots are encouraged to use the standard traffic pattern. However, those pilots who choose to execute a straight-in approach, maneuvering for and execution of the approach should not disrupt the flow of arriving and departing traffic. Likewise, pilots operating in the traffic pattern should be alert at all times for aircraft executing straight-in approaches.
REFERENCE-
AC 90-66, Non-Towered Airport Flight Operations.
NOTE-
2. *RP indicates special conditions exist and refers pilots to the Chart Supplement.
NOTE-
3. Right traffic patterns are not shown at airports with full-time control towers.
e. Wind conditions affect all airplanes in varying degrees. Figure 4-3-4 is an example of a chart used to determine the headwind, crosswind, and tailwind components based on wind direction and velocity relative to the runway. Pilots should refer to similar information provided by the aircraft manufacturer when determining these wind components. FIG 4-3-3 Traffic Pattern Operations Single Runway

Practice questions from our free FAA written test prep that cite AIM 4-3-3.
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.

When approaching to land at a non-towered airport, the recommended entry to the traffic pattern is:
- A. a 45° entry to the midpoint of the downwind leg at pattern altitude.
- B. a straight-in approach to the active runway.
- C. a direct entry to the base leg.
- D. an overhead break to the upwind leg.
Show answer
A. a 45° entry to the midpoint of the downwind leg at pattern altitude. The 45° entry to midfield downwind at pattern altitude puts you where everyone expects to see you. If you must cross overhead to reach it, cross at least 500 feet above pattern altitude and descend clear of the pattern flow.

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.

Which runway would be in use at a non-towered airport with runways 09/27, when the wind is reported from 260° at 12 knots?
- A. Runway 27.
- B. Runway 09.
- C. Either, since the crosswind is equal.
- D. Runway 26.
Show answer
A. Runway 27. Aircraft take off and land into the wind, and runway numbers are the magnetic heading rounded to the nearest 10 degrees, dropping the last digit. A wind from 260° favors runway 27 (270°). Knowing this tells you where arriving traffic will be.

Questions pilots ask
What is the standard traffic pattern altitude?
For propeller-driven aircraft the AIM recommends entering the pattern at 1,000 feet AGL, and for large and turbine-powered aircraft at not less than 1,500 feet AGL or 500 feet above the established pattern altitude (AIM 4-3-3a1 and a2). If the Chart Supplement publishes another pattern altitude, the AIM says to use that one (AIM 4-3-3a).
Are traffic pattern turns always to the left?
The AIM states that, unless otherwise indicated, all turns in the traffic pattern must be made to the left, except for helicopters as applicable (AIM 4-3-3c). Right patterns are marked "RP" with the runway numbers on sectional and VFR terminal area charts (AIM 4-3-3d).
How do I enter the traffic pattern?
The key to the AIM's single-runway pattern figure describes entering in level flight, abeam the midpoint of the runway, at pattern altitude, then maintaining pattern altitude on downwind until abeam the approach end of the landing runway (AIM 4-3-3, single-runway figure key items 1 and 2).
How far from the runway should I turn final?
The AIM's figure key says to complete the turn to final at least 1/4 mile from the runway (AIM 4-3-3, single-runway figure key item 3).
