Understanding Aircraft Noise in Our Community

Noise can be mitigated through a variety of strategies, including through a Federal Aviation Administration (FAA) Part 150 Noise Study ("Part 150 Study"). The airport implemented voluntary noise abatement procedures through a Part 150 Study in an effort to minimize community noise impacts; however, the procedures are implemented on a voluntary basis in accordance with federal law.

Since the introduction of the Presidential Temporary Flight Restriction (TFR) in November 2025, the FAA has adjusted flight procedures to ensure compliance with the new restrictions and operational requirements required by the U.S. Secret Service, which preclude the use of certain voluntary noise abatement procedures developed in accordance with the Part 150 Study.

Over the past few decades, improved aircraft engine technology has greatly reduced the amount of noise produced by engines. Airports across the country are using extensive noise abatement procedures, including preferred runways, delayed turnouts, and higher departure altitudes. DOA also has noise abatement staff, noise monitors and flight tracking systems to address community concerns.

Pilots are required to follow the directions of air traffic controllers and Federal Aviation Administration (FAA) regulations. Palm Beach County initiated a Noise Compatibility Study under Federal Aviation Regulation Part 150 (14 CFR Part 150), which is a voluntary program used to address airport noise and non-compatible land uses. Noise abatement procedures were approved by the FAA as part of the Part 150 process and are assigned by FAA Air Traffic Control as voluntary measures (wind, weather and traffic permitting); however, there is no penalty for failing to utilize noise abatement procedures.

The noise monitors measure sound levels in the community. They provide awareness of actual noise conditions as they occur, including both aircraft activity and everyday environmental sounds such as traffic, landscaping equipment and construction.

Community Day-Night Average Sound Level (DNL) is a metric displayed on the portal that reflects all “other” environmental noise measured at a monitoring site. It includes non‑aircraft sources such as vehicles, landscaping equipment and general neighborhood activity.

Aircraft Day-Night Average Sound Level (DNL) is a separate metric on the portal that isolates noise associated specifically with aircraft operations. It helps distinguish aircraft‑related noise from other community noise sources.

No. Neither Community DNL nor Aircraft DNL represents the FAA’s regulatory 65 Day-Night Average Sound Level (DNL). The FAA’s 65 DNL threshold is not a measured value. It is a modeled, annual average generated using the Aviation Environmental Design Tool (AEDT). This model incorporates annual aircraft operations, fleet mix, runway use and standardized flight profiles.

Monitor‑based Day-Night Average Sound Level (DNL) values are short‑term indicators. They reflect noise measured over a limited period and do not represent the Federal Aviation Administration’s (FAA) annual, modeled 65 DNL exposure. Because of this, they cannot be used to determine whether an area is considered “compatible” or “noncompatible” under FAA land‑use guidelines.

No. A single loud day, or even a short‑term reading above 65 Day-Night Average Sound Level (DNL), does not indicate that the FAA’s annual regulatory threshold has been met. The FAA’s 65 DNL standard is based on a full year of modeled data, not on individual events or daily fluctuations.

The monitors provide transparency and community‑level awareness of actual noise conditions. They help residents understand what they are experiencing in real time, even though the data is not used for regulatory determinations.

Airports often have certain traffic patterns that aircraft must follow to avoid collisions with other aircraft, buildings and landmarks. Wind direction and speed determine which runway will be used for takeoff and landing. Traffic patterns are dependent on which runways are in use.

Due to weather or wind conditions, aircraft are forced to use the most suitable runway to make safe landings. This, occasionally, causes planes to shift traffic patterns or flow, and land on runways that are not often used. Also, when runways are closed for various reasons, aircraft must use other runways that bring them over different neighborhoods.

Traffic patterns are designed for efficient and safe runway use at an airport. Noise considerations are always made in conjunction with these patterns. Aircraft must follow these paths in order to land safely. Transport aircraft are not physically designed to make sharp turns without creating certain safety hazards.

Individuals do not have specific rights to the airspace above their houses. There are any number of reasons why an aircraft may be operating over a particular house. 

Aircraft have to fly low to properly line up with the runways, execute safe landings and to avoid severe weather. Aircraft may, however, appear lower than they actually are because their large sizes make them appear closer. Also, when the airspace is crowded, aircraft may be held at a lower altitude to avoid conflicts with other aircraft. Approaching aircraft may spend time flying a holding pattern at relatively low altitudes to ensure a suitable flow of traffic. This may make it appear as though they are flying lower than usual. In general, air traffic is restricted by local airspace limitations. For complaints, contact South Florida Flight Standards District Office (faa.gov).

Varying weather and operational conditions influence the flight patterns of aircraft near airports. Wind has the greatest impact on flight paths as aircraft need to land and take off into the wind. As the wind changes, the flight paths change accordingly. This explains an airport's need to have multiple runways pointing in different directions. Also, depending on aircraft volume, air traffic control will put aircraft in holding patterns, increase aircraft spacing or set aside noise abatement procedures in the interest of safety. This may also occur because of air traffic limitations within our local airspace, possibly relating to neighboring airports. Aircraft are limited to where they can fly because of established flight paths, approach paths and departure paths. These paths are established and published to enhance safety during flight.

Aircraft are limited in the direction they fly because they must land into the wind. Therefore, the flexibility of air traffic is dependent on the wind patterns of the day or, even the hour, as winds can change rapidly. If the winds change, the air traffic controllers may need to change runway usage and, thus, the flight paths.

To enhance safety and ensure an efficient flow of traffic, airports follow an established pattern and as a result cannot change flight paths. There are also restrictions due to airspace limitations. An aircraft's speed and weight determines how far in advance it must line up with the runway to execute a safe landing. Typically, aircraft must be in line with the runway at least five miles out. 

The most efficient way airports can operate is to land and depart aircraft on certain runways for an extended period of time. This means that while the winds are blowing from a constant direction, the aircraft will always be flying into the wind. While approaching the airport, the aircraft will be in a line several miles apart, flying into the wind, getting ready to land. The repetition of aircraft you hear from the ground is the noise the "lined up" aircraft are making while on their approach or, in the opposite case, taking off.

Generally speaking, unless an aircraft is operating over sparsely populated areas, it is required to operate 1,000 feet above property on the ground except during takeoff or landing. For operations over sparsely populated areas, the requirement is 500 feet. Arriving and departing traffic at the airport are under the control of the Federal Aviation Administration (FAA). They ensure aircraft are flying at correct altitudes, speed and course. For complaints, contact: South Florida FSDO - Contact the Office (faa.gov).

Some traffic must fly at night to meet today's business needs. Companies like FedEx and UPS rely on night flights and are an essential part of our fast-paced business environment that guarantees overnight delivery to satisfy the needs of customers. Some traffic flies later at night to compensate for time differences in other parts of the world. Airports in the United States are required to be open 24 hours a day and cannot restrict operations due to federal law.

There are many different types of aircraft that fly today. Each type has different features and capabilities. Some aircraft make more noise than others because of the type of engines they have. Also, larger aircraft tend to make more noise than smaller aircraft, though this is not always the case. Your proximity to the aircraft affects the volume of sound you hear. The volume of noise also depends on the age of the aircraft. Newer aircraft have engines that are designed with technology so that they are quieter. Different engines and airframes have entirely different noises associated with flight. Most small non-jet aircraft do not fall under the noise level requirements established by the Federal Aviation Administration. Because of this, smaller aircraft may be even louder than larger aircraft.

Some aircraft tend to make a rumbling sound because their engines produce a lower frequency noise. This lower frequency is what causes vibrations. Newer engine designs reduce the amount of low frequency noise.

Aircraft must fly over residential areas because of the small distances between some airports and neighborhoods. Therefore, it is sometimes necessary for aircraft to fly over these residential areas in order for aircraft to safely reach the airports. Air traffic control procedures often try to minimize the number of aircraft flying over homes. For safety reasons, this is not always possible.

Aircraft must follow the glide slope approach when landing to allow for a safe and stable approach. The glide slope is an imaginary line that extends out from the end of the runway at a 3-degree angle. For safety reasons, aircraft cannot fly higher or lower than this line.

You may contact the Noise Hotline for President Donald J. Trump International Airport at 561-244-9510. We also have an online form for the public regarding noise issues. DOA also has the Citizens' Committee on Airport Noise (CCAN). Meetings are generally held four times a year. Dates and times are posted here.

The Federal Aviation Administration (FAA), under Federal Aviation Regulations (FAR) Part 36, governs the certification of aircraft as it relates to noise levels. Depending on the type of aircraft, FAR Part 36 determines the maximum allowable noise level. The FAA also follows the model of the International Civil Aviation Organization (ICAO), which sets global aircraft noise standards known as Stages. Currently, the FAA mandates that all aircraft that fly within the United States comply with Stage 3 requirements and all new aircraft comply with Stage 5 requirements, which are 17 decibels less than Stage 3. 

The federal government has jurisdiction over U.S. airspace. No individual may claim ownership of airspace over his or her property. Airspace is considered to be public domain and may be used by anyone as long as they do not interfere or endanger the people and property on the ground below. Once an aircraft pushes back from the gate, the airport no longer controls the movements or actions of the aircraft. The responsibility is shifted to the pilots and Air Traffic Control. The Federal Aviation Administration determines which runways are in use for arrivals and departures, or the pilot at an uncontrolled airport. Air traffic controllers are employed by the U.S. government or by private companies that are contracted by the U.S. government.

The Federal Aviation Administration (FAA) has the sole authority to control air traffic. Neither Palm Beach County nor DOA can regulate the altitude, speed, direction or location of aircraft in flight. If you have any questions about aircraft in flight or wish to report an unsafe flight operation, including low altitude flights, contact the local Flight Standards District Office (FSDO) at 954-641-6000 or visit their website: South Florida FSDO - Contact the Office (faa.gov).

In order to ensure the highest levels of safety and security for President Donald J. Trump, the U.S. Secret Service (USSS) has requested that the Federal Aviation Administration institute temporary procedural changes that restrict aircraft from flying directly over Mar-a-Lago. These changes are expected to be in place for the duration of the President’s term and mirror what was instituted during his previous presidency. The USSS recognizes that these procedural changes could have an impact on the public and has expressed its appreciation of the surrounding community’s understanding.

- Discuss aircraft noise with your realtor, as it may affect your satisfaction with your potential new home.

- Visit the home multiple times, on different days and at different times (time of year and weather affect aircraft noise). This will increase your chances of experiencing aircraft flights to determine what impact they will have on daily life.

- Make sure the realtor doesn't persuade you to visit during off-peak times or only times that are convenient to the realtor.

- Check the airport’s flight schedules for departure and arrival times so you can plan a visit to the home during busy hours.

- Be specific and be sure to ask your realtor, the neighbors and the current owner, if possible, about the impact of aircraft noise.

- Ask about any existing complaints or avigation easements attached to the house deed. If so, this means that the house is within 65 DNL, or in very close proximity, to the airport. Read the easement so you are aware of noise complaint procedures. Avigation easements (right of overflight in the airspace above or in the vicinity of a particular property) are perpetual.

- Be sure to address any additional concerns you may have with the real estate agent or owner.

The value of your house should not decrease because of its proximity to the airport or the aircraft noise; however, you should talk to a real estate agent that is familiar with land value around airports to get an accurate evaluation for your location.
