        "content": "At a non-towered airport like Fernandina Beach Municipal (FHB), there is usually no air traffic control to assign a runway in use. Instead, pilots use a combination of wind information, radio communications, visual indicators, published airport data, and standard procedures to decide which runway to use. Here's how it works in detail:\n\n---\n\n## Key Tools & Sources of Information\n\n1. **Wind Direction & Speed**\n   - Pilots aim to land and take off *into the wind*, since headwinds reduce ground roll and increase control.\n   - Airports often have *windsocks* or wind tees visible from the air or from taxiways to show wind direction. Pilots can overfly or observe these from safe altitude. ([airnav.com](https://www.airnav.com/airport/FHB?utm_source=openai))\n\n2. **Automated Weather Reports**\n   - Many airports, including FHB, have automated weather systems (AWOS) or similar broadcasts. Pilots listen to these to determine current wind conditions. ([airnav.com](https://www.airnav.com/airport/FHB?utm_source=openai))\n\n3. **Visual Indicators & Airport Signs**\n   - A *segmented circle* around airports may include landing strip indicators and possibly a *tetrahedron* (a small wind-direction indicator). The tetrahedron points in the preferred landing runway direction. But: in calm wind conditions they may not reflect the optimal runway or be misaligned; in any case, they\u2019re advisory only. ([airnav.com](https://www.airnav.com/airport/FHB?utm_source=openai))\n\n4. **Common Traffic Advisory Frequency (CTAF / UNICOM)**\n   - Pilots announce their position and intentions (e.g., \u201cFernandina Beach traffic, Cessna 1234, 10 miles south, will enter downwind for Runway 22\u201d) to coordinate with other traffic and find out what runway others are using. ([airnav.com](https://www.airnav.com/airport/FHB?utm_source=openai))\n\n5. **Published Information**\n   - Airport directories (like the FAA Chart Supplement or \u201cAirNav\u201d) list traffic patterns, published approaches, lighting aids, etc. These may note which runways have instrument approaches or are favored under certain conditions. ([airnav.com](https://www.airnav.com/airport/FHB?utm_source=openai))\n\n---\n\n## How Pilots Decide \u201cRunway in Use\u201d\n\nHere\u2019s the typical decision-process:\n\n1. **Get the wind info**: via AWOS, windsock, or other means. Determine which runway aligns best with wind to minimize crosswind or tailwind.\n\n2. **Check what's being used by others**: If other aircraft are already landing or taking off, use the same runway to maintain pattern conformity and reduce conflicts. Consistency helps everyone predict traffic flow. ([sites.google.com](https://sites.google.com/coyotehillconsulting.com/cfiwes/library/non-towered-airport-operations?utm_source=openai))\n\n3. **Use visual cues**:\n   - Windsock: which way is the flag pointing?\n   - Segmented circle / traffic pattern indicators.\n   - Tetrahedron: see which way it points (though be cautious in light winds). ([faa.gov](https://www.faa.gov/air_traffic/publications/atpubs/aip_html/part2_enr_section_1.1.html?utm_source=openai))\n\n4. **Announce intentions**: On CTAF, call out what you plan to do (\u201c\u2026final for Runway 22\u201d, etc.) so others are aware. That helps with situational awareness. ([sites.google.com](https://sites.google.com/coyotehillconsulting.com/cfiwes/library/non-towered-airport-operations?utm_source=openai))\n\n5. **Follow any published noise or local procedures**: Some airports have guidelines for preferred runways under certain conditions (e.g. calm winds), or to reduce noise over certain residential areas. FHB has a remark: \u201cDuring calm winds use RWY 22.\u201d ([airnav.com](https://www.airnav.com/airport/FHB?utm_source=openai))\n\n---\n\n## Specifics for Fernandina Beach Municipal (FHB)\n\n- FHB is **non-towered** \u2014 no control tower, operations always handled via pilot communications on CTAF. ([fbfl.us](https://fbfl.us/168/Airport-Information?utm_source=openai))\n- CTAF (same as UNICOM here) is **122.7 MHz**. ([airnav.com](https://www.airnav.com/airport/FHB?utm_source=openai))\n- FHB operates wind indicators and has segmented circles and pattern indicators for the runways. ([airnav.com](https://www.airnav.com/airport/FHB?utm_source=openai))\n- As per its NOTAMs and airport remarks: in calm winds, they request using Runway 22. ([airnav.com](https://www.airnav.com/airport/FHB?utm_source=openai))\n\n---\n\n## Example Scenario\n\nLet\u2019s say a pilot is approaching FHB:\n\n- They tune into AWOS or listen to airport automated weather: wind is from 220\u00b0 at 8 knots.\n- Looking at runway orientations (04/22, 09/27, 13/31), Runway 22 (225\u00b0 magnetic) is closest to into-wind (22 aligns with ~220).\n- They overfly the field, observe the windsock pointing slightly toward 22, and see aircraft currently using Runway 22 (downwind and base legs align accordingly).\n- They announce: \u201cFernandina Beach traffic, Cessna N1234, 10 miles south, inbound for landing, Runway 22, Fernandina Beach.\u201d Others respond or just hear and align with that.\n- If there\u2019s no wind or calm, and no traffic using another runway, they might follow local guidance (\u201ccalm winds use RWY 22\u201d) or pick based on other priorities (noise procedures or local terrain).\n\n---\n\n## Documents That Define These Procedures\n\n- **FAA Advisory Circular 90-66C** (Non-Towered Airport Flight Operations): outlines recommended procedures, including runway selection based on wind, using CTAF, pattern entry, etc. ([faasafety.gov](https://www.faasafety.gov/files/events/NM/NM07/2024/NM07133947/AC_90-66C_Non_Towered_Airports.pdf?utm_source=openai))\n- **FAA Advisor Circular AC-90-48E**: gives guidance on operations including runway usage, scanning for other traffic, using visual runway and pattern indicators. ([faa.gov](https://www.faa.gov/documentLibrary/media/Advisory_Circular/AC_90-48E.pdf?utm_source=openai))\n- **FAA AIM (Aeronautical Information Manual)** Chapter on non-towered operations: traffic patterns, communication, runway use etc. ([faa.gov](https://www.faa.gov/air_traffic/publications/media/AIM-Chg-2-dtd-3-21-24.pdf?utm_source=openai))\n\n---\n\nIf you like, I can walk you through how this works for other small airports, or go into published rules like pattern altitude, preferred traffic direction, etc."

Exactly what's included depends on the AWOS \u201clevel\u201d at a given field. Here\u2019s a breakdown of typical AWOS broadcasts and their components:  \n\n---\n\n## What an AWOS Broadcast Generally Includes\n\n1. **Prefix & Time**  \n   - Usually starts with the airport/location name.  \n   - It states \u201cAUTOMATED WEATHER OBSERVATION.\u201d  \n   - Time of the observation (in UTC/Zulu).  \n   - If the system is not fully commissioned or undergoing testing, the word \u201cTEST\u201d may be included.  \n   ([faa.gov](https://www.faa.gov/air_traffic/publications/atpubs/aip_html/part1_gen_section_3.5.html?utm_source=openai))\n\n2. **Wind**  \n   - Direction (in degrees magnetic), speed (knots), and sometimes gusts.  \n   - Variable wind direction if the wind swings significantly during measurement.  \n   ([faa.gov](https://www.faa.gov/air_traffic/publications/atpubs/aip_html/part1_gen_section_3.5.html?utm_source=openai))\n\n3. **Visibility**  \n   - Usually in statute miles.  \n   - If visibility changes rapidly, the system reports that.  \n   ([faa.gov](https://www.faa.gov/air_traffic/publications/atpubs/aip_html/part1_gen_section_3.5.html?utm_source=openai))\n\n4. **Clouds / Ceiling**  \n   - Sky condition: how much of the sky is covered by clouds (e.g. clear, few, scattered, broken, overcast).  \n   - Height of cloud bases (ceiling).  \n   - This often comes from a ceilometer (cloud height sensor).  \n   ([faa.gov](https://www.faa.gov/air_traffic/publications/atpubs/aip_html/part1_gen_section_3.5.html?utm_source=openai))\n\n5. **Temperature & Dew Point**  \n   - Provides both values, typically in degrees Celsius.  \n   - Dew point helps assess moisture, potential for fog or cloud formation.  \n   ([faa.gov](https://www.faa.gov/air_traffic/publications/atpubs/aip_html/part1_gen_section_3.5.html?utm_source=openai))\n\n6. **Altimeter Setting (Pressure)**  \n   - Barometric pressure adjusted for sea level, used to set an aircraft's altimeter correctly.  \n   ([aopa.org](https://www.aopa.org/news-and-media/all-news/2017/august/flight-training-magazine/how-it-works-awos-asos?utm_source=openai))\n\n7. **Density Altitude** (if applicable)  \n   - Often reported if it significantly exceeds field elevation by a threshold (e.g. more than 1,000 feet).  \n   ([faa.gov](https://www.faa.gov/air_traffic/publications/atpubs/aip_html/part1_gen_section_3.5.html?utm_source=openai))\n\n8. **Present Weather / Precipitation Type** (Optional, in higher AWOS levels)  \n   - Rain, snow, drizzle, sleet, hail, etc.  \n   - Thunderstorms or lightning detection in some systems.  \n   ([faa.gov](https://www.faa.gov/air_traffic/publications/atpubs/aip_html/part1_gen_section_3.5.html?utm_source=openai))\n\n9. **Additional Optional Data in More Advanced Systems**  \n   - Runway surface conditions (wet, dry, snow covered, etc.)  \n   - Freezing rain or ice accumulation sensors  \n   - Precipitation accumulation over time  \n   - Lightning annunciation  \n   ([faa.gov](https://www.faa.gov/documentLibrary/media/Advisory_Circular/AC_150_5220-16E_w-chg1.pdf?utm_source=openai))\n\n---\n\n## AWOS Levels & Their Capabilities\n\nAWOS systems are classified by how many sensors they include. These levels define what's reported, beyond just time and altimeter setting:\n\n| Level | Common Inclusions |\n|--------|------------------------|\n| AWOS-A | Only altimeter setting / pressure. ([faa.gov](https://www.faa.gov/air_traffic/publications/atpubs/aip_html/part1_gen_section_3.5.html?utm_source=openai)) |\n| AWOS-AV | Altimeter + visibility. ([faa.gov](https://www.faa.gov/air_traffic/publications/atpubs/aip_html/part1_gen_section_3.5.html?utm_source=openai)) |\n| AWOS-I | Adds wind, temperature, dew point, density altitude. ([faa.gov](https://www.faa.gov/air_traffic/publications/atpubs/aip_html/part1_gen_section_3.5.html?utm_source=openai)) |\n| AWOS-2 | Same as I level + visibility. ([faa.gov](https://www.faa.gov/air_traffic/publications/atpubs/aip_html/part1_gen_section_3.5.html?utm_source=openai)) |\n| AWOS-3 | Adds cloud cover / ceiling. ([faa.gov](https://www.faa.gov/air_traffic/publications/atpubs/aip_html/part1_gen_section_3.5.html?utm_source=openai)) |\n| AWOS-3P / AWOS-3T | Adds precipitation *type* (P) and/or lightning/thunderstorms (T). ([faa.gov](https://www.faa.gov/air_traffic/publications/atpubs/aip_html/part1_gen_section_3.5.html?utm_source=openai)) |\n| AWOS-4 | Highest level: full \u201c3P/T\u201d plus freezing rain, runway surface conditions, accumulation sensors, etc. ([faa.gov](https://www.faa.gov/documentLibrary/media/Advisory_Circular/AC_150_5220-16E_w-chg1.pdf?utm_source=openai)) |\n\n---\n\n## Example: A Hypothetical AWOS-3 Report (Voice Format)\n\nSomething like:\n\n> \u201cFernandina Beach Automated Weather Observation, 1445 Zulu. Wind 210 at 8, visibility 10 miles, ceiling broken at 2,500 feet, overcast at 5,000 feet. Temperature 25, dew point 18. Altimeter 30.05 inches.\u201d\n\nIf this were an AWOS-3P, there might be an extra phrase like:\n\n> \u201c\u2026Rain beginning. Present weather: light rain.\u201d\n\n---\n\nIf you want, I can pull up an actual recent AWOS broadcast from Fernandina Beach or another similar airport so you can hear what pilots actually receive."

        "content": "Yes, when there's no ATC assigning runways at a non-towered airport, pilots use predefined rules, local procedures, and \u201csense\u201d of the best runway to use based on wind, conditions, and other factors. The final decision lies with the pilot\u2010in\u2010command (PIC), but there are many published guides and some local \u201ccalm wind runway\u201d preferences that help standardize things so everyone is more predictable.\n\nHere\u2019s how a pilot knows (or decides):\n\n---\n\n## How Runway Decision Is Made Without Tower\n\n1. **Pilot\u2019s Responsibility**  \n   - The FAA rules give the PIC ultimate authority for runway selection based on safety. The PIC must consider wind, runway condition, obstacles, aircraft capability, etc. ([faa.gov](https://www.faa.gov/air_traffic/publications/atpubs/aip_html/part2_enr_section_1.1.html?utm_source=openai))  \n   - At non\u2010towered airports there is no \u201cactive runway\u201d assigned by ATC; any runway \u201cin use\u201d is selected by pilots coordinated through radio and observation. ([askacfi.com](https://www.askacfi.com/34572/cross-wind-landing-at-non-tower-airport.htm?utm_source=openai))\n\n2. **Wind is Key**  \n   - Pilots want to use a runway aligned as closely as possible with the wind to maximize headwind component and minimize crosswind or tailwind. This improves safety and performance. ([sites.google.com](https://sites.google.com/coyotehillconsulting.com/cfiwes/library/non-towered-airport-operations?utm_source=openai))  \n   - Even if the AWOS doesn\u2019t say which runway to use, it provides wind direction and speed; using that, plus runway headings, pilots pick the runway whose heading is most closely aligned *into* the wind. ([aviation.stackexchange.com](https://aviation.stackexchange.com/questions/126/whats-a-quick-way-to-determine-which-runway-to-use?utm_source=openai))\n\n3. **Local Published Preferences (When Winds Are Calm or Light)**  \n   - Some airports publish a *calm-wind runway*: a preferred runway to use when wind is very light or variable. At Fernandina Beach (FHB), the published calm-wind runway is Runway 22. ([flightaware.com](https://www.flightaware.com/resources/airport/KFHB/remarks?utm_source=openai))  \n   - Airport remarks, directories (like the FAA Chart Supplement or AirNav), and noise abatement or community guidelines often list calm-wind runway preferences. ([aopa.org](https://www.aopa.org/Kneeboard/Kneeboard/GeneratePdf?airportId=KFHB&utm_source=openai))\n\n4. **Other Considerations**  \n   - If other aircraft are already in the traffic pattern or using a particular runway, it\u2019s safe and courteous to use the same one. It helps everyone predict traffic flow. ([sites.google.com](https://sites.google.com/coyotehillconsulting.com/cfiwes/library/non-towered-airport-operations?utm_source=openai))  \n   - Terrain, obstacles, runway length, surface conditions (wet, snow, etc.), published traffic patterns (left or right\u2010hand) all might influence runway decision. ([sites.google.com](https://sites.google.com/coyotehillconsulting.com/cfiwes/library/non-towered-airport-operations?utm_source=openai))  \n   - Noise abatement: many fields request or require avoiding overflight of certain areas; local guidelines may favor a runway for noise purposes when safety allows. ([fbfl.us](https://www.fbfl.us/DocumentCenter/View/22880/Noise-Abatement-Guidelines---Final?utm_source=openai))\n\n---\n\n## Case Study: Fernandina Beach (FHB)\n\nHere\u2019s how those rules apply at FHB:\n\n- **Calm\u2010wind runway**: \u201cDuring calm winds use Runway 22\u201d is published in the airport remarks. ([flightaware.com](https://www.flightaware.com/resources/airport/KFHB/remarks?utm_source=openai))  \n- **Noise abatement guidelines** also request using Runway 22 when wind allows. ([fbfl.us](https://www.fbfl.us/DocumentCenter/View/22880/Noise-Abatement-Guidelines---Final?utm_source=openai))  \n- If wind direction (from AWOS) is closer to aligning with another runway (e.g. runway 04 or 09), and other pilots are using it, a pilot might decide to use that instead. But if winds are light or variable, the calm runway (22) is preferred.  \n\n---\n\n## Example Scenarios\n\n- **Wind from 210\u00b0 at 8 knots**: Runway 22 (approximate heading 220\u00b0) would give a good headwind component; likely use Runway 22.  \n- **Winds from 050\u00b0 at 5 knots**: Very light wind; since 22 is the calm runway, one might still use 22, unless there\u2019s heavier traffic using a runway more aligned with the wind.  \n- **Winds from 310\u00b0 at 12 knots**: Harder tailwind/tolerance; maybe choose runway closest to 310\u00b0, such as Runway 31, if conditions allow (length, power, obstacle).  \n\n---\n\nIf you like, I can lay out a checklist pilot-studies use at non-towered fields to decide runway, or show some sample runway headings matching winds, to help visualize."

([pilotrise.com](https://pilotrise.com/wp-content/uploads/2025/05/Untowered-Airport-Communications.pdf?utm_source=openai)) |\n\n---\n\n## Example Scripts / Phrases\n\nHere are some example CTAF calls (incoming, circuit, departure):\n\n- Approaching from distance:  \n  *\u201cFernandina Beach traffic, Cessna N123AB, 10 miles south at 2,500 feet, inbound landing Runway 22, Fernandina Beach.\u201d*  \n\n- At downwind:  \n  *\u201cFernandina Beach traffic, Cessna N123AB, left downwind Runway 22, touch-and-go, Fernandina Beach.\u201d*  \n\n- On final:  \n  *\u201cFernandina Beach traffic, Cessna N123AB, final Runway 22, full stop, Fernandina Beach.\u201d*  \n\n- Departure:  \n  *\u201cFernandina Beach traffic, Cessna N123AB, taking off Runway 22, departing north, Fernandina Beach.\u201d*  \n\n- After clearing runway:  \n  *\u201cFernandina Beach traffic, Cessna N123AB, clear of Runway 22, taxiing to parking, Fernandina Beach.\u201d*\n\n---\n\n## Why This Matters\n\n- **Safety & situational awareness**: Without ATC, everyone depends on each other sharing what they\u2019re doing. If you hear a plane say \u201cfinal Runway ___,\u201d you know which runway is in use. ([americanflyers.com](https://americanflyers.com/tips-for-flying-at-a-non-towered-airport/?utm_source=openai))  \n- **Predictability and traffic flow**: Following standard patterns and announced intentions helps avoid conflicts and makes everyone\u2019s flight path more predictable. ([pilotinstitute.com](https://pilotinstitute.com/common-non-towered-airport-mistakes/?utm_source=openai))  \n- **Looking out for lost/quiet traffic**: Because some aircraft might not have radios, or pilots might delay their call, it's standard to *listen* before transmitting and keep scanning visually. ([pilotinstitute.com](https://pilotinstitute.com/common-non-towered-airport-mistakes/?utm_source=openai))\n\n---\n\nIf you want, I can show you the official wording from FAA publications like AIM or the specific advisory circulars so you can see exactly how these announcements are supposed to be worded."

        "content": "Here are the standard parts (\u201clegs\u201d) of a visual traffic pattern used at many U.S. airports (especially non-towered ones), what they mean, and how pilots fly them. The definitions follow FAA guidance (AIM, Airplane Flying Handbook, AC 90-66C). ([piperowner.org](https://piperowner.org/wp-content/uploads/2023/07/Advisory-Circular-Regulations.pdf?utm_source=openai))\n\n---\n\n## The Legs of a Traffic Pattern\n\nA typical traffic (rectangular) pattern consists of six legs:\n\n| Leg | Location | Purpose / What the Pilot Does |\n|---|----------|-------------------------------|\n| **Departure Leg** | After takeoff along runway\u2019s extended centerline | Climb straight ahead, gaining altitude. This is the initial segment after lift-off. If staying in the pattern, pilot transitions to the crosswind leg. ([faatest.com](https://www.faatest.com/books/FLT/Chapter7/AirportTrafficPatterns.htm?utm_source=openai)) |\n| **Upwind Leg** | Along the extended centerline, same direction as takeoff | Sometimes, after departure pilots may fly this leg if they continue straight ahead rather than turning immediately. AIM defines \u201cupwind leg\u201d as separate from the \u201cdeparture leg\u201d in certain contexts. ([faraim.org](https://www.faraim.org/faa/aim/244/aim-244.pdf?utm_source=openai)) |\n| **Crosswind Leg** | 90\u00b0 from runway off the departure end | Pilot makes a 90\u00b0 turn from departure/upwind, either still climbing or leveling off, heading perpendicular to the runway. Used to set up the downwind leg. ([faatest.com](https://www.faatest.com/books/FLT/Chapter7/AirportTrafficPatterns.htm?utm_source=openai)) |\n| **Downwind Leg** | Parallel to runway, opposite landing direction | Pilot flies with runway on one side (\u201cmidfield\u201d) at traffic pattern altitude, about \u00bd to 1 mile from the runway. Important time to do pre-landing preparations (e.g. configure aircraft, complete checklists). ([en.wikiversity.org](https://en.wikiversity.org/wiki/Airplane_Flying_Handbook/Standard_Airport_Traffic_Patterns?utm_source=openai)) |\n| **Base Leg** | At right angles to runway, off the approach end | After downwind, pilot turns base. This leg gives time to align for final approach. Usually descending gradually. Make the turn from base to final ensuring no conflict with traffic on final. ([faasafety.gov](https://www.faasafety.gov/files/events/SO/SO15/2022/SO15112841/AirplaneFlyingHdbkChp8.pdf?utm_source=openai)) |\n| **Final Approach Leg** | From base-to-final turn, aligned with runway centerline | This is the path for touchdown. Pilot lines up runway centerline, manages descent rate, airspeed, and aligns visually for landing. Final segment before runway touchdown. ([en.wikiversity.org](https://en.wikiversity.org/wiki/Airplane_Flying_Handbook/Standard_Airport_Traffic_Patterns?utm_source=openai)) |\n\n---\n\n## Additional Details & Rules\n\n- **Traffic Pattern Altitude (TPA)**: Usually 1,000 feet above ground level (AGL) for small aircraft, unless otherwise noted. All aircraft should maintain this while in the pattern. ([faatest.com](https://www.faatest.com/books/FLT/Chapter7/AirportTrafficPatterns.htm?utm_source=openai))  \n- **Pattern Direction**: By default, patterns are **left-hand**, meaning all turns are to the left. Right-hand patterns are used when required by terrain, noise abatement, or runway layout, and are published in airport directories. ([faatest.com](https://www.faatest.com/books/FLT/Chapter7/AirportTrafficPatterns.htm?utm_source=openai))  \n- **Distance from Runway (Width of Pattern)**: Typically \u00bd to 1 mile away from runway during downwind leg, though pilot judgment takes over based on traffic, wind, obstacles. Too wide can reduce visibility of traffic; too close may conflict with ground obstacles. ([en.wikiversity.org](https://en.wikiversity.org/wiki/Airplane_Flying_Handbook/Standard_Airport_Traffic_Patterns?utm_source=openai))  \n\n---\n\n## How a Pilot Flies Through the Pattern\n\nHere\u2019s an example of how a pilot might fly the pattern:\n\n1. **Takeoff** \u2192 climb on the *departure leg* / immediately on runway heading.  \n2. Turn into the **crosswind leg** when safe (enough altitude, clear of the departure end).  \n3. Turn into **downwind**: parallel to the runway but flying opposite the landing direction. At pattern altitude, a set distance from runway. Perform pre-landing checks.  \n4. When past the runway\u2019s approach end and aligned about 45\u00b0 abeam touchdown point, turn **base**.  \n5. From base, turn onto **final**: align with runway centerline, descending to land.  \n\n---\n\nIf you want, I can draw a diagram or send you a visual image showing all legs so you can see how it looks in the sky / from above."
