TEB is an extremely busy GA airport near NYC
Executed Part 150 study
Well-designed flight tracks, preferential runway use and useful rules
Teterboro Airport (TEB), operated by the Port Authority of New York & New Jersey, is one of the nation’s busiest (2016: 178,369 aircraft operations, averaging 488 per day: 65.6% general aviation, 34% air taxi, 0.3% military, and <1% airline. 121 aircraft were then based at this airport: 81% jet, 10.7% helicopter, 6.6% single-engine, and 1.7% multi-engine. It is located in the suburban New Jersey only 10 miles from downtown Manhattan.
TEB, with clear challenges, has done an excellent job of addressing noise. After reviewing the noise impacts of its flights on its neighbors through a Part 150 process, management has designed an array of flight tracks and runway preferences to minimize impacts. A well-designed noise program is based on careful consideration of
substantial command of the technical operations constraints,
recognition of the limitations defined by safety
understanding of the air traffic control efficiency optimization
The TEB Aircraft Noise Compatibility Plan is an aggressive set of tactics.
One of the cardinal rules of safety is standardization, standardization and standardization. Adding to the complexity of piloting, particularly during critical phases of flight, like take-off, reduces the margin of safety. The TEB noise plan is built on the NBAA Noise Abatement Departure Procedure, so the crews are likely to be familiar with this flight profile.
Adding to cockpit awareness is another sound technique to mitigate noise. If the pilot knows how the departure, for example, affects the community, (s)he will be more sensitive to where the aircraft should operate carefully.
While all of this information helps to conform patterns to the Noise Abatement Design, it is the structure of the departure/arrival lines, the preferential runway times/directions and the sagacious choice of difficult alternatives. The Part 150 sessions assessed all the options and sought input from all of the stakeholders.
Winnowing down the array of permanent flight patterns involves balancing community, safety, operations and safety to a balanced solution.

NBAA continues working with airport authority to reduce aircraft noise.
The people on and around the airport in Teterboro, New Jersey (KTEB)—one of the busiest general aviation airports in the nation at 302,000 takeoffs and landings—take aircraft noise very seriously. My introduction to the Port Authority of New York & New Jersey employees who keep an eye on arrivals and departures occurred when a noise office van pulled up next to the Hawker I was flying as we shut down at the FBO. The warning citation the Port Authority official handed me had time-stamped data that showed our arrivals a few minutes earlier had surpassed the limit set on the local noise sensor that guards Runway 6. I came to realize that another violation could cost me—and possibly the company—so I made sure I never again made the same mistake on future visits.
NBAA says exceeding Teterboro’s mandatory noise limits by 1 dB (A) earns a violation; three violations in two years bans the offender from the airport. Runway 1/19 has KTEB’s highest maximum noise level, 95 dB (A), at all times. The maximum noise levels for Runway 6/24 is 80 dB (A) between 10 p.m. and 7 a.m. and 90 dB (A) between 7 a.m. and 10 p.m. The Teterboro authority highly recommends using Runway 19 because it reduces the risk of exceeding the 80 dB(A) limit and avoids noise-sensitive communities. [Teterboro has a “three strikes and you’re out” program for noise violators. It basically states that if an aircraft operator violates the noise threshold more than three times in a two-year period, the aircraft can be banned from operating at TEB. The program was in place prior to the Airport Noise and Capacity Act of 1990, and thus was grandfathered. In addition, the airport has a voluntary nighttime operations restriction; a 100,000-lb. aircraft restriction; and, a ban on scheduled air carrier service.]
During the current COVID-19 pandemic, noise awareness of corporate jet traffic at KTEB has actually increased in the communities that surround airports, according to the NBAA. “Some days operations at [Teterboro] surpass those at [KEWR] and [KLGA]. To remain within the maximum noise limits operators must use FAA-approved procedures, manufacturer recommendations or NBAA-recommended noise abatement departure procedures. The airport also urges voluntary restraint of all nonessential operations between 11 pm and 6 am.”
Gabriel Andino, Teterboro’s manager of noise abatement and environmental compliance, and chair of the NBAA Access Committee Airports Working Group, says, “It may seem counterintuitive in wide open skies, but operators are encouraged to be even more vigilant about following voluntary noise abatement procedures.”
To continue the authority’s efforts to reduce noise, Teterboro is receiving three new RNAV approaches, Andino said. “RNAV Y (GPS) 19 overlays an existing ILS with an RNAV; RNAV (GPS) X RWY 19 is an offset approach to Runway 19 that will be made available to address noise concerns north of the airport. RNAV (GPS) RWY 24 provides an instrument approach to Runway 24, a runway that previously didn’t have one. RNAV (GPS) Y 19 and RNAV (GPS) RWY 24 have been published, but an additional environmental review has pushed RNAV (GPS) X RWY 19 to the first quarter of 2021.”
Good planning is usually a reliable predicate to good outcomes. There have been occasions where the theoretical collided with the practical. Hopefully TEB results in minimization of its flights’ impact on its neighbors.
