Introduction This report is prepared for the Rhode Island General Assembly in conformance with the Permanent Noise Monitoring Act of 1998, as amended. It contains statistical information on aircraft operations, activity levels by aircraft types, and noise complaints for the Second Quarter, 2007. T. F. Green Airport is a medium-hub commercial service airport located in Warwick, RI. It serves the Rhode Island, Southern Massachusetts and Eastern Connecticut communities. In the mid-1990s, Southwest Airlines began service at T.F. Green which resulted in a significant increase in aircraft operations and the ability for travelers in the southern New England area to reach many destinations easily and affordably. The airport has two active runways, 5-23 and 16-34. Runway 5-23 is 7,166 feet long and 150’ feet wide. It is oriented in a north/south direction and serves as the primary runway for large turbojet operations. Runway 16-34 is the “crosswind” runway oriented in a northwest/southeast direction. It is 6,081 feet long and 150 feet wide and is utilized as weather conditions dictate. T.F. Green was among the first airports in the country to participate in the Federal Aviation Administration’s Noise and Land Use Compatibility Program, commonly referred to as Part 150. Under the direction of the State of Rhode Island and now the Rhode Island Airport Corporation, T. F. Green Airport has had an active noise mitigation program since the early 1980s. In 1998, RIAC undertook a complete update of the original Part 150 Study and recommended several new operations procedures designed to minimize noise impacts on surrounding communities. The center of these recommendations involved the implementation of noise abatement departure procedures for turbojet aircraft. In June 2000, the FAA approved these new procedures and the local air traffic control tower implemented the assigned departure headings in an effort to reduce the number of persons adversely affected by aircraft operations.

Permanent Noise Monitoring Act In 1998, the Rhode Island Legislature enacted Title 1, Aeronautics, Chapter 1-5, Permanent Noise Monitoring Act – Aircraft Operations Monitoring System (AOMS). This Act requires the Rhode Island Airport Corporation (RIAC) to install an aircraft operations monitoring system. Once installed, RIAC is to collect and report on a quarterly basis detailed and summary information related to the operation of aircraft at Green Airport. This document is generated to meet those requirements. The AOMS is a stand-alone system that has five (5) radar sensors deployed throughout the State of Rhode Island (see Figure 1). These sensors receive specific aircraft information from all aircraft with transponders operating within 20 miles of T. F. Green Airport. This information is delivered real-time to the Noise Program Manager where it is correlated daily and displayed on a computer screen. The data is archived for use in generating reports.

Information collected includes; aircraft type, flight number, registration number, altitude, arrival/departure status and the origin or destination. The use of five sensors throughout the state allows for a greater accuracy in identifying the flight tracks. This system is independent from the Federal Aviation Administration (FAA) air traffic control radar. The movement of aircraft to and from an airport is the responsibility of FAA Air Traffic Control.

Passenger Activity Airports use two different criterions to measure activity for an airport, the number of operations and the number of passengers. This section discusses the passenger activity levels associated with aircraft operations at T. F Green Airport. T. F. Green served approximately 1,314,595 passengers during the second quarter, an 18.55% increase over the previous quarter. Passenger levels decreased approximately 4% over the same quarter 2006. Passenger decrease can be attributed to a number of factors some of which are decreases in airline seating capacity by Delta and American Airlines; American Airlines ending its service to Dallas and Chicago; and Spirit Airlines discontinuing their service on the 30th of April. Southwest will begin daily nonstop service to Ft. Lauderdale beginning June 4th as well as adding a sixth daily flight to Orlando. In addition, on June 22nd Azores Express will commence a weekly nonstop service to the Azores. Figure 2 shows the number of passengers that have utilized the airport via scheduled air carriers, commuter and charter flights since 2006. Figure 2: Total Passengers, by Quarter

Aircraft Operations Aircraft operations can be classified in a number of ways including by type of aircraft, arrivals/departures, origin/destination, airline fleet, Part 36 (relative noisiness) and time of day. To present the overall perspective of operations, Table 1, highlights the arrivals and


Second Quarter 2007

departures of all aircraft by runway at T. F. Green Airport. In general aircraft must take off into the wind, therefore, aircraft also arrive into the wind to remain consistent with the traffic flow and avoid aircraft departing and arriving in the same direction. As previously stated there are two runways at T. F. Green, 5-23 and 16-34. Runways are given numbers based on the compass heading for each runway end. By designating each runway end, the Tower and pilots know which direction to land or depart. For example, Runway 5 has a compass heading of 050 degrees and is oriented to the north. Aircraft operating on this runway will depart to the north and arrive from the south. Conversely, Runway 23 has a heading of 230 degrees and is oriented to the south. Aircraft operating on Runway 23 will depart to the south and arrive from the north.

Total Operations The Aircraft Operations Monitoring System (AOMS) collected 30,121 flight tracks during this reporting period. There were 15,247 departures and 14,874 arrivals for an average 331 operations per day1. Table 1 depicts aircraft operations by runway and operation type.2 Table 1: Total Operations by Runway, 2nd Quarter 2007

Departures were divided equally between Runways 5 and 23 with a majority of arrivals from the north on Runway 23. As the weather turns warmer, there is a marked decrease in the number of operations utilizing the crosswind runway (Runway 16-34). Figure 3 depicts this runway use graphically over an aerial view of the airport.

1 On April 16, 2007, due to weather related construction damage, the airport was closed to air carrier operations

from 2:00 am until 12:30 pm. 2 Detailed record of operations by aircraft type and time of day can be found on T.F. Green Airport’s website,

www.pvdairport.com, listed under Quarterly Aircraft Operations Report, 2nd Quarter, 2007.

The balance of this report will highlight the scheduled commercial aircraft and cargo operations, since these operations are the primary focus of the noise abatement efforts and Part 150 Study as well as the predominant operator category at the airport.

Part 36 Certification During the 2nd Quarter of 2007 there were approximately 8,323 departures of commercial aircraft from T. F. Green Airport, which averages out to approximately 91 operations per day. This number includes air carrier, commuter and cargo operations. The overall percentage of pure Stage 3 aircraft operating at T. F. Green Airport is at a high of 97% or 8,069 operations during this quarter. Figure 4: Schedule Departures by Noise Classification, 2006 - 2007

Source: RIAC, Airline Activity Reports and Operations Monitoring System, 2005-2007

The airlines (air carrier and commuter) accounted for 8,053 (97%) of the 8,323 commercial departures from T. F. Green Airport, (Table 2). The airlines are operating at 99% pure Stage 3 aircraft and 1% Stage 3 compliant (hushkitted Stage 2 aircraft). The cargo carriers operating at T. F. Green account for 181 (71%) of the 254 hushkitted Stage 2 aircraft operations. In addition there were 22 (9%) charter aircraft that were Stage 3 compliant. All airline operations are scheduled to occur between 6:00 a.m. and midnight. Table 2 also illustrates each scheduled air carrier’s contribution to daily flights and percentage use of the quietest aircraft.

Late Night Operations (Midnight – 6:00 a.m.) RIAC has implemented a voluntary nighttime curfew for operations between midnight and 6:00 a.m. therefore; the airlines have no flights scheduled during this time period. However, should a flight be delayed for weather or mechanical reasons, it will continue to operate so that passengers will not be unduly disrupted. Airline operations conducted the greatest number of late night operations during this quarter with 155 operations. Total commercial aircraft (air carrier and commuter) conducted 255 operations. There were 140 general aviation operations, 1 charter flight, 2 military and 2 life safety flights during curfew hours. 193 or 48% of the late night operations occurring between midnight and 1:00 a.m. and 86 or 22% occurring between 1:00 and 2:00 a.m. are comprised mainly of arrivals (Figure 5). During the month of June, there was an increased number of late night operations due to several severe storms.

Southwest Airlines, United Airlines, and U.S. Airways operated the most late night operations. It should be noted that this accounts for a small percentage of the individual airlines total operations at T. F. Green. The majority of these operations were arrivals attributed to weather or air traffic delays at the originating airports. Figure 6: Late Night Operations, by Airline, by Operations

Part 150 Noise Abatement Corridor Compliance The Part 150 Noise Study Update recommended the implementation of noise abatement departure corridors to limit the number of persons adversely affected by aircraft noise near T. F. Green. After an FAA Environmental Impact Statement, RIAC implemented the use of noise abatement corridors beginning in June 2001. There are a total of eight corridors, comprised of at least one departure corridor per runway and one arrival corridor for Runway 34. For most runway ends; there are two flight tracks that jet aircraft may follow. The Air Traffic Control Tower issues a departure heading associated with one of the Part 150 corridors based on the aircraft’s destination. A description of these flight corridors is presented below and a graphical depiction of the corridors is shown in Figures 8 and 9.


Second Quarter 2007

of 22


Runway 5: Northbound Departures (D5NA): Jet aircraft will turn left as soon as practicable after passing runway end to fly a 360-degreee heading until reaching 3 DME (Distance Measuring Equipment). Southbound Departures (D5SB): Jet aircraft will turn right to a 080-degree heading until reaching 3 DME, passing over Passeonkquis Cove, Gaspee Point Beach and Narragansett Bay. Runway 23: Northbound Departures (D2SA): Jet aircraft will turn left as soon as practicable after passing runway end to a 160-degree heading until reaching 5 DME or intercepting the 180-degree radial (whichever occurs first). This measure is intended to route traffic over Greenwich Bay and along the north edge of Goddard Memorial State Park. Southbound Departures (D2NA): Jet aircraft will turn right as soon as practicable after passing runway end to a 280-degree heading until reaching 3 DME. This measure is intended to direct departures under 3,000’ over compatible land use areas in Apponaug along I-95 and SR 115. Runway 16: Southbound Departures (D1SA): Jet aircraft will turn right to a 180-degree heading until reaching 3 DME or intercepting the PVD VORTAC 180-degree radial. This measure is intended to direct departures over compatible land use areas along Brush Creek Cove and Greenwich Bay. Runway 34: Northbound Departures (D3NA): Jet aircraft will turn left as soon as practicable after passing runway end to a 330-degree heading until reaching 4 DME. This measure is intended to direct departures along compatible land use areas located along SR37 and I-295. Southbound Departures (D3SA): Jet aircraft will turn right to a 360-degree heading until reaching 3 DME. This measure is intended to direct departures along compatible land use areas along I-95 and the Pawtuxet River corridors. Runway 34: Arrivals (A3SA): Jet aircraft will intercept the final approach course before crossing the shoreline at Rocky Point Beach on Warwick Neck (4 DME from the PVD VORTAC). This measure is intended to keep jet aircraft following the same course along the extended runway centerline from beyond the shoreline.
