February 2011 Department of Conservation announced that DOC will require all aircraft concession holders and all aircraft operators that want to work in the DOC Estate to be AIRCARE™ Accredited by April 2012.

Extended to 1/01/13 (incl. Milford) (24/01/12)

New Applications: on application or by 1/01/13 (whichever comes 1st.)

Page 5: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

DOC will achieve this by mandating in the CMS reviews currently underway.

Extended concessions

Page 6: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

The biggest threat to aircraft activities is poorly written legislation being developed to protect the environment.

The way the industry is reacting to that is to develop the AIRCARE™ Program

The AIRCARE™ Program is an enabling program.

Page 7: Aircare ™  Code of Practice for Aircraft operators Noise Abatement
Page 8: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

The AIRCARE™ Accreditation Program includes codes of practice about discharges (Spraying, Topdressing & aerial poison drops) engineering and Amenity Values (the Noise Abatement Code)

 

Page 9: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

SMS that sits above the codes requires that operators are independently audited against both the SMS and the codes.

To be awarded accreditation an operator has to prove compliance with the relevant code(s) every time they go to work.)

Compliance Flowchart

Page 11: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

ENVIRONMENTALCode of Practice for Aircraft Operations

-Amenity Values

-NOISE ABATEMENT

Page 12: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

In accordance with the requirements to preserve amenity values as described in the RMA, aerial operators need to manage noise.

By following the principles detailed in this code, that can be achieved.

Page 13: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

This code forms part of the Environmental Management System offered as part of the AIRCARE SMS run by the Aviation Industry Association of NZ.

 It recognises the issues involved with the operation of aircraft in and around noise sensitive areas

Details a plan by which the aviation industry and regulators can work together in order to achieve the long term goal of limiting the noise and environmental impact of aircraft

Page 14: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

With a proactive approach the aviation community can pre-empt legislation being enforced upon the industry that could itself be unworkable.

Does not address: Aircraft Noise measurement

Page 15: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Members of the aviation community are invited to join this accreditation program that both trains and measures pilots and operators in ‘flying neighbourly’ and in noise abatement methods.

The aviation community needs work with regulators to identify measures that reduce the impact of aircraft noise.

Page 16: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Amenity values Means those natural or physical qualities and

characteristics of an area that contribute to people’s appreciation of its pleasantness, aesthetic coherence, and cultural and recreational attributes

Noise Sensitive Area An area where the impact of adverse effects

from noise diminishes the amenity values of that area

Excludes CBD but may include residential areas and smaller towns between 1900 – 0700.

Populous Area A collection of ten residences or more in an area less

than two hectares, or a gathering of more than 100 people.

Page 17: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

The Resource Management Act 1991 empowers legislators to control elements of

aircraft operations e.g. noise as it impacts on amenity values.

Does not control overflight

The Civil Aviation Act 1990 empowers the CAA to control aircraft

operations. The Civil Aviation Act does not empower CAA to have any control of aircraft noise. Notwithstanding this, the majority of complaints that CAA fields are noise related

Does not control noise

Page 18: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

The Conservation Act 1987, Specifically Part 3B Concessions Section 170

(2) says that no activity will be carried out in a conservation area unless authorized by a concession.

The National Parks Act 1980 Specifically Section 14 Wilderness Areas

s14(2)(d) This clause prohibits aircraft landing or hovering in Wilderness Areas.

Page 19: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

What has changed?? RMA 1991 CA Act 1990 Conservation Act 1987 Nat. Parks Act 1980

Tolerance has changed What was considered normal or acceptable in

years gone by is no longer so.

Page 20: Aircare ™  Code of Practice for Aircraft operators Noise Abatement
Page 21: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Culture has to change The measure of a pilot

Crashes Productivity

Least breakages Most versatile / professional/ lowest insurance risk

What is needed now is both helicopter and fixed wing operators and pilots who adapt the quickest

Page 22: Aircare ™  Code of Practice for Aircraft operators Noise Abatement
Page 23: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Understanding the impact of noise on the environment and on amenity values and how that noise can be effectively managed is about:

Staying in business

Keeping your job

Page 24: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

There are sounds that please us

And there are noises that disturb us

Not everyone likes the same types of noise

Page 25: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Irrespective of the sound /noise being generated, the environment will dictate its character. F1 GP, Airshows, Jet ski carnivals

Churches, Nat. Parks, schools, hospitals, holiday resorts, outdoor gatherings / concerts

More peaceful the environment the bigger the impact

Page 26: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

NOISE – CAUSE & REMEDIES Fixed wing

Propeller (design & speeds) retrofitable Settings & sync

Set RPM at lowest recommended setting in all flight phases

100 rpm difference in mid-range of prop setting will raise or lower noise emission by 3 - 5 dB.

High rpm very intrusive and increases at higher end of prop rpm setting (2450 rpm upwards)

2600 – 2700 rpm setting can double perceived sound at ground level (Rayward)

Stuff them. Ignore them and they will go away

Get right up ‘em. Best form of defence is attack.

There’s always a couple of moaners. No one else seems to have a problem.

We were operating here long before they came along.

Page 39: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Wait ‘til they break a leg. Then they’ll be pleased to see us.

We’ve got a job to do, so they might as well get used to it.

Not much I can do about it.

Page 40: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Some more sensitive to noise than others Noise inducted vibration & rattle A/c noise irritating low frequency content Helicopter noise more irritating than

f/wing Periodic impulsive character

Personal judgement, fear and negative attitude

Industry’s response to these concerns……….

Page 41: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Confusion of legislation leads to unsatisfactory results for complainants

Ignored or fobbed-off. Frustration Concerns need to be listened to Soon settle down when they realise they

are being heard Nearly all will be satisfied when they see

some response to their concerns

Page 42: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

For the purposes of this Code the word “shall” refers to practices that are mandatory for compliance with the Code and the word

“should“ refers to practices that are advised, recommended or are industry best practice.

Page 43: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Pilots Attend & pass Fly Neighbourly training

Take all reasonable steps to minimise noise footprint

Comply with Code of Practice and company procedures except:

Notify operator when conditions cannot be complied with

Page 44: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

To meet the requirements of this code pilots shall complete the Fly Neighbourly training program and pass an assessment set by the AIA. The term of this qualification shall be three

years. The Fly Neighbourly Guide upon which this

training is based is included as Appendix 1.

Page 45: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Pilots shall take all reasonable steps to minimize their noise footprint. In flight, pilots should observe the following noise abatement procedures:

Avoid noise-sensitive areas where possible

Follow high ambient noise routes Maintain an altitude as high as possible Fly normal cruising speed or slower Avoid sharp manoeuvres

Page 46: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

use steep takeoff and descent profiles (helicopters only) – Vy -5kts

Operate (f/wing)propellers at the low end of the propeller recommended RPM operating range for all phases of the flight.

Vary the route, repetition contributes to annoyance.

Page 47: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

For low level operations – use techniques that minimise the noise footprint: operating RPM (rotor or prop). keeping high ground or shelter belts between

flight tracks and any nearby residence hours of operation and timing of operation.

Where company (or User Group) operating areas or transit routes are developed, confine flights to those places.

Page 48: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Comply with the Code of Practice except where they would conflict with: Flight safety, or C A Rules, or ATC clearances or instructions, or Passenger comfort. A/c limitations

Pilots unable to comply with company Policy or guidelines in respect to noise abatement shallshall document the event and notify the operator using an Event Notification form.

Page 49: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Operators Policy on noise minimisation and plan

operations accordingly Emphasise awareness of noise sensitive areas Consider fleet , a/c type selection Maintain a noise complaints register Ensure staff attendance at FN courses Ensure pilot’s ongoing awareness and

understanding of noise minimisation

Page 50: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Operators (cont.) Include FN in Management Review Meetings Promote customer education Maintain active participation in Airspace User

Groups

Page 51: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

To meet the requirements of this code operators shall: Maintain a policy on noise minimisation that

shall be promoted to all staff.

This policy shall reflect the operator’s intent to reduce the amount of noise created by aircraft and

other equipment. ????

The policy will identify current and anticipated areas of noise concern.

Page 52: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

To meet the requirements of this code operators shallshall: Plan flight ops in accordance with noise

abatement procedures to minimize the impact of aircraft movements giving consideration to:

a/c type selected Time of day or week to be least obtrusive.

In sensitive areas, develop the location of operational areas and transit routes in consultation with the any relevant parties or local authorities.

Page 53: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

To meet the requirements of this code operators shall: Assist flight crews and operations personnel to

develop responsible mission profiles without infringing on operational reality, without conflicting with CARs, ATC instructions, or a/c operating limitations.

These guidelines shall emphasize awareness of sensitive routes and landing areas.

Page 54: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

To meet the requirements of this code operators shall: For low level operations near populous areas, consider the fleet and select an aircraft type

that has the least intrusive noise footprint.

Page 55: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Maintain a register of noise complaints including: the name and address of the complainant, location of the concern and the date and time to which the event refers. corrective and preventative actions undertaken

Evaluate and discuss with pilot concerned. Review procedures

Page 56: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

To meet the requirements of this code operators shall ensure all relevant staff:

attend the Fly Neighbourly training course

pass an assessment on the noise abatement procedures detailed in that course.

undergo recurrent training and assessment every three years.

Page 57: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Operators shall ensure pilots awareness and understanding of the following is assessed during routine company flight checks (FCCC, Ag Comp.)

Contents and updates of manufacturers published noise abatement information (Flt. Manual Supps)

Documented company noise abatement policies and procedures

Operational noise minimisation techniques

Page 58: Aircare ™  Code of Practice for Aircraft operators Noise Abatement
Page 59: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

To meet the requirements of this code operators shall: As part of regular Management Review

Meetings (required under the AIRCARE Environmental Management System), ensure that the noise minimisation policy is considered to ensure that it is still relevant in respect to any changing conditions or legislation and that it is revised when required.

Page 60: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

To meet the requirements of this code operators shall: Educate customers about noise abatement

prevent or minimize conflicts between their expectations and company policy.

Where a User Group has been established maintain membership and take an active part in its activities.

Strive for continuous improvement .

Page 61: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

It is recommended that operators adopting this code of practice should: Where possible, when operations below 500ft

AGL are anticipated, arrange notification to all affected parties near the proposed flight path.

 Promote the safety record and the benefits of aircraft use to improve public acceptance of aircraft.

Develop good working relations with the media presenting favourable aircraft related media coverage of events, achievements and outcomes including Fly Neighbourly seminars.

Page 62: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

It is recommended that operators adopting this code of practice should: Engage in public relations to develop awareness of

the the company’s Fly Neighbourly Program through attendance at meetings of local government, government agencies, service clubs and environmental groups.

 Utilise demonstrations and press conferences covering such capabilities as fire fighting, emergency medical evacuation, search and rescue and the benefits of aircraft transportation to the general public.

Page 63: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Land-owners Administrators Notify visitors / neighbour etc. who might be

affected

Page 64: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

When aircraft operations are planned over sensitive areas, it is the responsibility of the Land Owner/Administrator to notify people who could be adversely affected by the aircraft noise.

Doing this will reduce the element of surprise and disappointment that often lead to frustration for visitors and owners/administrators alike.

Page 65: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Examples: Restaurant / lodge owners - neighbours Visitors to the DOC Estate – a/c noise Visitors to National – a/c noise and track /

hut work Landowners/Administrators should work

with aircraft operators to identify flight routes that will cause the minimum of noise nuisance.

Page 66: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Acceptance of aircraft activities is, in general, poor.

Engender acceptance. Provide media with : valid and favourable aviation related information

(e.g. press releases - good news stories) SAR ops, local police support, fire fighting

Get involved with Govt agencies – Influence their thinking and decisions Partner with them to promote your services

Page 67: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Publicise F/N seminars and initiatives Front-foot it with:

Changes to operational practices Establishing a new base

Consider safety, operational and environmental issues

Develop a public acceptance program

Programs to prevent or resolve complaints Use the media to project positive relations

Utilise local, national and trade media Av News, Pac Wings, Kiwi Flyer etc.

Good noise - bad noise Aircraft make lots of it. Multiple noise sources from helicopter:

RotationalRotational (main & tail rotors) Directional downwards & forward

ImpulsiveImpulsive (BVI, TRI, HSI) Most obtrusive Most easily remedied

BroadbandBroadband Less obtrusive except start-up, hover

Page 79: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Distance Double distance (or altitude) = 5-6 db noise

reduction = halved perceived noise Temperature

Lower temp= greater noise Humidity

Higher humidity – greater noise Wind

Downwind – greater noise Terrain

Page 80: Aircare ™  Code of Practice for Aircraft operators Noise Abatement

Main rotor speed Design – blade structure, mechanics

Anti torque design Blade speed, blade spacing Alternatives (notar)
