Some overall Vector operations statistics

Recorded approximately 26,000 operations (roughly 13,000 takeoffs / 13,000 landings) from 11/1/13 – 10/31/14 Conducted by approximately 2,600 specific aircraft

Approximately 25% of all annual operations were conducted by 25 specific aircraft 14 helicopters 5 single turbopropeller seaplanes 5 other propeller aircraft 1 jet

The aircraft that flew the most operations over the entire year was a twin-engine piston propeller

The second most frequently operated aircraft was a single engine turbopropeller seaplane

Piston props are moderately “seasonal” and are the most active

off-season

Many aircraft conduct multiple operations a day

Turboprops 12 5Piston Props 9 6

HTO is not a typical general aviation airport where users (other than pilots conducting training operations) typically conduct only one or two operations on a given day

It is not unusual for a specific aircraft to conduct multiple round trips on a given day

Multiple round trips are most common in helicopters and turboprops, particularly around weekends in season

Almost identical toannual, because most

operations and complaintsare in the season

22

Complaints per operation observations

Complaints about fixed-wing operations Increase in a roughly “linear” or “straight-line” fashion Even during busiest hours, there is never more than one complaint per

operation on average for jets, seaplanes, or other propeller operations

Complaints about helicopter operations People are far more likely to complain about helicopter operations

than jet, seaplane, or other propeller operations The rate at which helicopter complaints are submitted increases faster

than the rate at which operations increases On average, there is more than one complaint per helicopter operation

in any given hour

“Seasonal” and annual results are essentially identical Because most operations and complaints are in the season

23

Noise from aircraft operating at East Hampton Airport disturbs many residents of the east end of

Long Island.

Residents find helicopters more disturbing than any category of fixed-wing aircraft.

(Helicopter complaints increase faster than the rate at which operations increase.)

Noise from aircraft events disturbs many residents of the east end of Long Island.

Residents find helicopters more disturbing than any category of fixed-wing aircraft.

Residents are most disturbed by all types of aircraft operations under two circumstances: (1)

during evening and night hours, and (2) when operations are most frequent.


26

Problem Definition

Noise from aircraft operating at East Hampton Airport disturbs many residents of the east

end of Long Island. Residents find helicopters more disturbing than any

category of fixed-wing aircraft. Disturbance caused by all types of aircraft is most

significant when operations are (1) most frequent and (2) in evening and night hours.

2. BansBan “noisy” aircraft

Alternatives that have been rejected as not reasonable

No action

Noise mitigation

Fee-based restrictions To address the problem, the fee would have to be high enough

to change behavior Such a high fee may not be reasonable under federal law Fee-based alternatives run a high risk of unintended

consequences, e.g., practical limits on who can use the airport, including users of light aircraft

30

Alternatives that merit additional review

Several alternatives are not directly responsive to the problem statement

Additional analysis is needed to determine effectiveness and reasonableness

31

Ban(s)

Can a ban address the problem? Ban “noisy” aircraft

– In general, jets are louder than helicopters on a single event basis– Complaints, however, appear to respond to frequency and timing of

operations rather than decibel level Ban specific aircraft types (e.g., helicopters)

– Residents do find helicopters most disturbing– Complaints, however, appear to respond to frequency and timing of

operations rather than aircraft type Ban specific types of operations (e.g., touch-and-go)

– Residents have cited touch-and-go patterns as an issue– Complaints, however, appear to respond to frequency and timing

rather than type of operation

32

Voluntary measures

Can voluntary measures address the problem? Existing voluntary measures

– Result of many years of testing and refinement Need to analyze 2014 data

– Was compliance better in 2014 than in 2013? Need to coordinate with operators

– How do we measure effectiveness?

33

Required routes or altitudes

Are required routes or altitudes a “reasonable” answer? Required routes or altitudes might address the problem The Town itself has no authority to regulate aircraft in flight The Town could encourage FAA to enforce optimal flight paths

34

Possibly reasonable alternatives

Time of day/week/year restrictions Restricting/prohibiting operations during evening/night/early a.m.

and/or peak periods would address the identified problem Example:

– Evening, night, and early morning curfew Air traffic flow management

Implementing a “slot” system to limit concentrated operations for any given time or day would address the identified problem

Examples:– Focus on individual aircraft conducting multiple arrival/departure

“cycles” on a given day and require advance permission for multiple cycles on any day

– Require advance permission during peak periods

35

Finding the solution to the problem

One alternative alone may not address the problem Recommend that the Town consider a menu of options

** ILLUSTRATION ONLY **

1. Curfew. Close airport during

evening, night, and early morning.

2. Slot/allocation system.

- Limit the number of hourly

arrivals. - Prohibit multiple, daily arrivals by

any given aircraft .

- Require advance permission for

operation in peak periods.

3. Compliance and Enforcement.- Vector Airport Solutions is responsible for monitoring.- Violations are misdemeanors subject to civil penalties. - Exemptions for emergency and safety circumstances.
