Standard traffic pattern altitude is 1,000 feet above ground level for propeller-driven aircraft and 1,500 feet AGL for large and turbine-powered aircraft, as published in the FAA’s Aeronautical Information Manual.1Federal Aviation Administration. Aeronautical Information Manual – Section 3. Airport Operations Helicopters fly the pattern at 500 feet AGL. Individual airports can publish different altitudes for terrain, obstruction, noise, or airspace reasons, so the Chart Supplement is the last word for any specific field.
Standard Altitudes by Aircraft Category
The AIM sets three baseline altitudes based on the aircraft you’re flying.
- Propeller-driven aircraft fly the pattern at 1,000 feet AGL. That altitude gives most single-engine and light twin airplanes a workable glide back to the runway if the engine quits, while keeping the field in easy sight.
- Large and turbine-powered aircraft fly at 1,500 feet AGL, or 500 feet above the established pattern altitude, whichever is higher. The extra height accounts for faster approach speeds and wider turn radii.
- Helicopters fly at 500 feet AGL, closer to the runway than fixed-wing traffic. They may fly the pattern on the opposite side of the runway from airplanes when airspeed differences demand it or when practicing autorotations, if local policy allows.
These figures apply unless the Chart Supplement publishes something different for the airport, or unless the cloud-clearance requirements of 14 CFR 91.155 force an adjustment.1Federal Aviation Administration. Aeronautical Information Manual – Section 3. Airport Operations Gliders enter at whatever altitude allows a continuous descent to the runway, since they cannot maintain level flight in the pattern. Pattern size itself scales with the aircraft: a Cessna 152 flies a tighter rectangle than a King Air, even at the same altitude.
You hold pattern altitude through the downwind until at least abeam the approach end of the landing runway. That is where power comes back and the descent begins.2Federal Aviation Administration. Airplane Flying Handbook – Chapter 8: Airport Traffic Patterns Starting down earlier on the downwind compresses the base and final legs and leaves you low on options if anything goes wrong.
Finding the Altitude for a Specific Airport
The Chart Supplement
The Chart Supplement, formerly the Airport/Facility Directory, is the authoritative source for airport-specific data. It does not list a pattern altitude for every airport. It publishes an altitude only when the field uses something other than the AIM’s recommended standards. If the entry is silent, the standard applies: 1,000 feet AGL for propeller-driven aircraft, 1,500 feet AGL for large or turbine-powered aircraft.3Federal Aviation Administration. Airport Facility Directory (AFD) Depiction of Traffic Pattern Altitudes When a non-standard altitude is published, it appears in both mean sea level and above ground level. The MSL figure is what you set on the altimeter; the AGL figure tells you how far above the ground you actually are.
VFR Sectional Charts
Sectional charts do not usually print a pattern altitude value. What they show is pattern direction. The abbreviation “RP” followed by a runway number, such as “RP 18,” indicates right traffic for that runway. An asterisk in front (“*RP”) means additional restrictions apply, and you have to check the Chart Supplement for details.4Federal Aviation Administration. Aeronautical Chart User’s Guide Airports subject to special air traffic rules under 14 CFR Part 93 appear with a boxed airport name.
Electronic Flight Bags
ForeFlight, Garmin Pilot, FlyQ, and similar tools pull from the same FAA source database and display non-standard pattern altitudes on the airport information page. They are convenient references, not substitutes for the official Chart Supplement, because EFB databases sometimes lag behind updates.
NOTAMs for Temporary Changes
Temporary pattern changes — for construction, a new obstruction, an airshow — travel through the Notice to Air Missions system. A NOTAM D must be issued for any change of traffic pattern at an airport, and it stays active until the underlying condition is resolved.5Federal Aviation Administration. NOTAM Criteria – Movement Area NOTAMs Checking NOTAMs before every flight is where these temporary altitudes live; missing one puts you at a different altitude than everyone else who checked.
Why Some Airports Publish Higher or Lower Altitudes
Terrain and Obstructions
The standard 1,000-foot figure assumes relatively flat terrain. When mountains, ridgelines, or hills sit close to the pattern, the published altitude rises to provide clearance above the highest nearby obstacle. Tall towers or building clusters near the approach path can have the same effect.
High-elevation airports create a related problem. The AGL pattern altitude may look standard, but density altitude degrades aircraft performance. At a field sitting at 6,000 feet, true airspeed on approach runs noticeably higher than at sea level for the same indicated airspeed, and climb performance drops off.6Federal Aviation Administration. Density Altitude (FAA-P-8740-02) Pilots trained at low-elevation airports often fly a pattern that is too tight when they arrive at a mountain field.
Noise Abatement
Residential development near an airport is a common driver of non-standard altitudes and routing. The FAA evaluates noise as part of its airspace analysis, and when it identifies problems, it may establish non-standard patterns or special arrival and departure procedures that route traffic away from sensitive areas.7Federal Aviation Administration. Evaluating Aeronautical Effect Some airports publish voluntary noise-abatement procedures asking pilots to fly higher or avoid specific neighborhoods. Others have mandatory procedures backed by local ordinances or FAA special flight rules. The Chart Supplement entry and NOTAMs identify which category applies.
Nearby Controlled Airspace
Proximity to restricted areas, military operations areas, or the shelf of a nearby Class B or C airport can push a pattern altitude above or below the standard. The adjustment keeps pattern traffic from drifting into airspace where different rules and different controllers apply. Every deviation from standard at a given field traces back to one of these factors: terrain, obstructions, noise, or airspace boundaries.
Are the Altitudes Regulatory or Just Recommended?
The specific numbers — 1,000 feet, 1,500 feet, 500 feet — are AIM recommendations, not regulations. The binding rules in 14 CFR Part 91 focus on traffic flow, turn direction, and compliance with published procedures rather than fixing an exact altitude. That distinction matters less than pilots sometimes assume, because the FAA has broad regulations that cover the gap.
Non-Towered Airports
14 CFR 91.126 governs operations at airports in Class G airspace and requires all turns to the left unless the airport displays approved visual markings or light signals indicating right turns.8eCFR. 14 CFR Part 91 Subpart B – Section 91.126 Helicopters, gyroplanes, and other non-fixed-wing powered aircraft must avoid the flow of fixed-wing traffic rather than mirror it. Section 91.127 extends the same rules to airports within Class E airspace.9eCFR. 14 CFR 91.127 – Operating on or in the Vicinity of an Airport in Class E Airspace
Towered Airports
At airports with an operating control tower, 14 CFR 91.129 applies. No one may take off, land, or taxi on a runway without an ATC clearance.10eCFR. 14 CFR 91.129 – Operations in Class D Airspace Controllers can sequence you differently than the published pattern — a tight base entry, an extended downwind, a straight-in — and you have to comply. The published pattern altitude is the baseline; the controller’s real-time instruction overrides it.
Enforcement When You Deviate
Ignoring a controller’s instruction in controlled airspace without declaring an emergency violates 14 CFR 91.123.11eCFR. 14 CFR 91.123 – Compliance with ATC Clearances and Instructions Separately, 14 CFR 91.13 prohibits operating any aircraft in a careless or reckless manner that endangers life or property.12eCFR. 14 CFR 91.13 – Careless or Reckless Operation The FAA uses 91.13 as a catch-all: even at a non-towered field where no controller instruction was involved, flying the pattern at the wrong altitude in a way that endangers other traffic can produce enforcement. Consequences range from warning letters for minor incidents up to certificate suspension, depending on circumstances and the pilot’s history.
Weather Minimums That Force a Different Altitude
You cannot fly the pattern under Visual Flight Rules unless weather meets the minimum visibility and cloud-clearance standards for the airspace you’re in. The relevant floors:
- Class B: 3 statute miles visibility, clear of clouds.
- Class C and D: 3 statute miles visibility, 500 feet below clouds, 1,000 feet above, and 2,000 feet horizontal.
- Class G at or below 1,200 feet AGL in daytime: 1 statute mile visibility, clear of clouds. At night the requirement rises to 3 statute miles with 500 feet below, 1,000 feet above, and 2,000 feet horizontal.
When the ceiling falls below 1,000 feet inside controlled airspace, standard VFR operations are not permitted.13Federal Aviation Administration. Aeronautical Information Manual – Airspace A Special VFR clearance lets fixed-wing aircraft operate with 1 statute mile of flight visibility while remaining clear of clouds, but it requires an ATC clearance and is only available in controlled airspace that extends to the surface. Fixed-wing Special VFR takeoffs and landings are prohibited when ground visibility is below 1 statute mile. At night, Special VFR for fixed-wing aircraft requires an instrument-rated pilot and an instrument-equipped aircraft.14eCFR. 14 CFR 91.157 – Special VFR Weather Minimums Meeting those minimums may mean flying a lower pattern than the published altitude, or not flying at all.
