Noise Program

The Noise Program at Witham Field began in the early 2000s with the 14 CFR Part 150 Noise Compatibility Program. The Airport Noise Advisory Committee was established in August 2003 as recommended by the Federal Aviation Administration due to the findings of the Part 150 Noise Study. 

Through subsequent noise studies and recommendations, noise abatement procedures, the voluntary nighttime curfew, and other measures have been adopted by Witham Field to actively mitigate aircraft noise over the local community.

Part 150 Noise Study

The Part 150 Noise Study is a voluntary noise compatibility planning program that follows guidelines from the Federal Aviation Administration to determine land use and noise impacts on the communities adjacent to Witham Field.

The study develops a noise compatibility plan and noise exposure maps using current operations models, determines compatible land use based on noise exposure levels surrounding the airport, and provides recommendations based on the data and forecasts to help mitigate aircraft noise impacts.

As a result of past Part 150 Noise Studies, the FAA has approved recommendations such as posting noise abatement signs by the runways, the voluntary nighttime curfew, and the Residential Sound Insulation Program (RSIP), as well as provided grant funding to implement various mitigation strategies for Witham Field. View the Part 150 Noise Study and Noise Exposure Maps (PDF).

Noise Abatement

Pilots operating under instrument flight rules should use current FAA published instrument departure procedures. Pilots operating under visual flight rules should follow the arrival and departure procedures found in the Noise Abatement Procedures (PDF). For additional information on noise abatement procedures, please refer to the FAA Chart Supplement publication for Witham Field (SUA).

Airport Noise Advisory Committee

The Airport Noise Advisory Committee (ANAC) is a group of community members that meet quarterly to discuss the impacts of aircraft noise and possible solutions that could be implemented.

Noise Curfew Report

The Voluntary Curfew Report provides a summary of aircraft operations at Martin County Airport / Witham Field during the voluntary curfew hours from 11 p.m. to 7 a.m. It is intended to give the community insight into nighttime flight activity, recorded noise calls from the community, and the airport’s efforts to encourage noise reduction. 

The data highlights when operations occur outside the recommended curfew period and helps track overall compliance trends over the previous four months. View the latest Voluntary Curfew Report (PDF).

Report a Noise Concern

There is a voluntary nighttime curfew from 11 p.m. to 7 a.m. for all aircraft (all prop aircraft, helicopters, and Stage I, II, and III jet aircraft). The only exceptions to this curfew are Air Ambulances, Rescue Aircraft and United States Government Aircraft, for which there are no curfews.

Report by Phone

To report airport noise, please call our Airport Noise Concern Hotline at (772) 221-1476. Please provide your address, the date and time of the operation, the location of the operation if it is different from your home address, and the nature of your concern.

If you would like a call back, please leave your name and phone number. Calls will only be returned if a call back phone number, home address, and/or email is included in your message.

Noise FAQs

The following frequently asked questions provide information about airport operations, aircraft procedures, noise management efforts, and community programs associated with Martin County Airport / Witham Field.

Witham Field operates as a general aviation airport, supporting activities such as corporate aviation, flight training, medical flights, and other aviation services that benefit the community and regional economy. There are currently no plans for Witham Field to become a commercial service airport.

Aircraft operating at Witham Field follow procedures established by the Federal Aviation Administration (FAA), including Standard Instrument Departure (SID) routes designed to guide aircraft safely through the surrounding airspace while helping reduce overflights of residential areas when possible.

At times, aircraft routing may vary due to weather conditions, air traffic flow, airspace requirements, or aircraft performance characteristics, all of which help ensure safe and efficient flight operations.

Aircraft operating near Witham Field follow procedures and instructions established by the Federal Aviation Administration (FAA) and air traffic controllers to ensure safe and efficient operations. Altitudes may vary depending on several factors, including the type of aircraft, aircraft performance capabilities, the runway in use, and overall air traffic conditions.

In some cases, weather conditions, airspace requirements, or other operational considerations may require pilots to operate at different altitudes while arriving or departing the airport. These adjustments are coordinated by air traffic controllers to maintain safe separation between aircraft and efficient use of the airspace.

Temporary Flight Restrictions (TFRs) are issued by the Federal Aviation Administration (FAA) to temporarily manage airspace during certain events, security situations, or special activities. When a TFR is in place, aircraft operations in and around Witham Field may be subject to specific procedures or limitations established by the FAA.

These restrictions are designed to ensure safe and secure use of the airspace. Pilots operating in the area receive guidance from the FAA and Air Traffic Control to comply with the requirements while continuing to operate safely and efficiently.

Witham Field has a voluntary nighttime curfew that encourages pilots and operators to limit departures and arrivals during late evening and early morning hours when possible. This program was developed as part of the airport’s ongoing effort to be a good neighbor and help minimize nighttime noise impacts for nearby communities.

The aviation community has shown strong cooperation with this program, with an approximately 98% compliance rate.

Because the curfew is voluntary, there may occasionally be flights during these hours. In some cases, aircraft may need to operate outside of the recommended hours due to factors such as weather, safety considerations, medical or emergency flights, or other operational needs.

Witham Field continues to work closely with pilots, tenants, and aviation partners to encourage participation in the voluntary curfew and promote responsible operations whenever possible.

The Residential Sound Insulation Program (RSIP) at Witham Field is a federally funded program administered under the guidance of the Federal Aviation Administration (FAA). The program is designed to help reduce aircraft noise inside certain homes located near the airport through improvements such as enhanced insulation and other sound-reducing features.

Participation in the program is determined by FAA eligibility criteria, which may include factors such as a home’s location relative to the airport, interior noise exposure levels, when the home was purchased, and the availability of FAA funding. The Airport administers the program in accordance with FAA requirements.

Aircraft operating at Witham Field generally follow a standard traffic pattern altitude of approximately 1,000 feet above ground level (AGL). This altitude helps pilots maintain safe and consistent operations while arriving and departing from the airport.

During takeoff and landing, aircraft may operate at different altitudes as they climb to or descend from the traffic pattern. Pilots are trained to follow established procedures and safely navigate around ground features such as antennas, buildings, and trees while transitioning to the runway or the standard traffic pattern altitude.

These procedures are designed to ensure safe and efficient aircraft operations in the airspace surrounding the airport.

Flight training is a common activity at general aviation airports and is one of the many aviation services offered at Witham Field. As a public-use airport that receives federal funding from the Federal Aviation Administration (FAA), the airport operates under FAA Grant Assurances that require airports to provide fair and equal access to aviation services without economic discrimination.

Because flight training is a recognized aviation activity available to the public, airports that accept federal funding cannot prohibit these operations. Currently, two flight schools operate at Witham Field, providing pilot training and contributing to the airport’s overall aviation services and operations.

Flight training also plays an important role in developing the next generation of pilots and supporting the broader aviation industry.
