Increase Safety / Mitage Aircraft Noise
Kilkenny Aerodrome adheres to strict aircraft noise and flight safety standards. Over its 56 year history it has always maintained an excellent relationship with the community. We want to ensure this is always the case.
Aircraft Noise & the Law
According to the EPA Act 2002 - 2006, aircraft noise is exempt.
According to the Environmental Protection Agency Act 2002 - 2006, aircraft Noise is exempted as a noise nuisance.
Section 108 (4)(a) expressly exempts aircraft noise as a nuisance.
The Department of the Environment, Community and Local Government requires that:
"Complaints about aircraft noise are specifically exempted from the Noise Regulations and should be directed to the airport authority in question or to the Department of Transport. Please also refer to the section on the Environmental Noise Regulations 2006." Click Here
Procedure For Reporting Aircraft Noise Complaint
We take aircraft noise very seriously and wish that all flights are carried out in accordance with best practice. We are responsible operators and we depend on you to help us mitigate noise. We are limited in our control over aircraft noise - which is subject to a wide range of factors including pilot, passenger and aircraft safety all of which are materially affected by weather conditions.
We welcome feedback from the public who feel they are affected by noise and we are committed to addressing complaints. Please submit complaints in writing and we recommend you provide the following details to help us investigate your complaint:
1. Your full name and address, contact info.
2. Date and time of aircraft noise matter.
3. Registration of the aircraft.
4. Type of aircraft (helicopter, fixed wing (single or twin engine, glider, canopy, paramotor, microlight or aerobatic)
4. Details of your complaint to help us gather a clear picture.

Aircraft Noise Complaints
Aircraft Noise Factors
Aircraft Noise Certifiation:All certified aircraft that operate to and from Kilkenny Aerodrome are required to be issued with a Noise Certificate from the national state of the aircraft's registration.
Non-Certified Aircraft: For any non-certified aircraft to operate in and out of Kilkenny Airport is must be issued with a permit to fly from the Irish Aviation Authority or other national authority.
Noise Mapping: Noise Mapping regulations are only required to be adhered to for airports in the State that receive over 50,000 movements per year. Kilkenny Airport has nowhere near 50,000 movements and is not affected by these regulations. Currently, only Dublin Airport is the only airport affected by this usage.
Aircraft Noise - Factors: Aircraft noise is affected by several factors. Measuring noise is complex matter and there are various methods and instruments available. In general the following are common factors in particular for General Aviation, Light Aircraft.
Propeller Diameter: The larger the propeller, the faster the speed of the tips rotate on the blade. If the blade tips exceed the speed of sound the effects can be a significant increase in sound. Our noise abatement procedures means we do not allow any aircraft to be permanently based at the aerodrome whose propeller(s) tips exceed the sound barrier.
Engine & Exhaust: The engine model and type (piston v turbine) is a factor. Noise from any engine is reduced through the exhaust system. The issue with aircraft is that unlike cars or normal vehicles, it is not possible to retro-fit any part one desires to any certified aircraft because there are rigorous certification requirements laid down by the European Aviation Safety Agency (EASA).
Weather Conditions: Different types of weather effect the transmission of noise through the air. Wind and air temperature are most significant.
Aircraft Noise Abatement Procedures: It is not always possible for safety reasons but aircraft can be flown and operated in a more noise friendly manner. The pilot may have scope to reduce power setting after takeoff which reduces noise impact. The approach and departure to the aerodrome and being careful to avoid overflying private residence at low altitudes is also important.
In general, the circuit pattern height of the aerodrome is 1000 AGL. No aircraft should be any lower than this in the vicinity of the aerodrome unless it is taking off or preparing to land.
Flying Training Aircraft: Aircraft flights for flight training, frequently involve aircraft flown by student pilots either on solo sortie or while under instruction by a qualified Flight Instructor. The flights involve intense aerodrome circuit training whereby the flight conducts repeated takeoff and landings (Touch and Go). This is an essential part of the pilot training program.
While conducting circuit training the the flight remains within the circuit height of Kilkenny Aerodrome, which 1,000ft AGL (Standard circuit height). The pilots will vary the pattern from a left hand to a right hand pattern (either runway 09 or 27 depending on wind) as part of the aerodrome noise abatement procedure.
Aerobatics: Aerobatics involved high powered aircraft performing high speed aerial manoeuvres, loops, rolls and spins. The Aerodrome noise abatement procedure means an aerobatic aircraft is not permitted to perform these high engine powered drills below 1000ft AGL.
Skydiving / Gliding: The altitude at which the aircraft ascends can range from 2,000ft up to 12,000ft. Once established at the pre-determined height the skydiving canopies and gliders will be released and glide and return to the aerodrome. Although, gliders/skydiving canopies are practically silent. The aircraft used to lift, for our noise abatement procedures, is required to avoid operating/climbing overhead the same area in a repeated manner. For this reason the pilot is required to vary the climb pattern (depending on the wind) - subject to weather limitations. The distance and range from the aerodrome is 8-9 nautical miles. This is the internationally recognised method of mitigating aircraft noise impact. Cloud cover has a great effect on the freedom the pilot has over the navigation of the aircraft. Once the gliders/skydiving canopies are released the aircraft reduces power to a very low setting (just enough to keep engine temperatures controlled) while descending overhead the aerodrome for landing.
Helicopters / Rotorcraft: It is widely accepted that helicopter and rotorcraft emit the highest noise by far over any other aircraft type. Helicopter aircraft have the ability to approach the aerodrome from any direction and does not necessarily need to approach or depart the runways in the same way fixed aircraft need to. Heli traffic also will typically fly at much lower heights then fixed wing aircraft. It is the noise abatement policy that helicopter traffic is required to approach and depart the runways in the same manner as fixed wing aircraft.
Suggestions & Feedback: We are willing to consider any reasonable suggestions you might have for inclusion in our Fly Neighborly Policy at Kilkenny Aerodrome. If you have any suggestions to submit please do so in writing and email to - firstname.lastname@example.org
IMPORTANT: Control & responsibility of aircraft navigation once the aircraft is airborne and has departed the Aerodrome Runway rests in the first instance with the pilot-in-command of the aircraft and thereafter Air Traffic Control and Irish Aviation Authority. The Rules of the Air is applicable to all flights conducted within the State and in this regard, aviation is a highly regulated activity. The pilot-in-command of any aircraft has full responsibility for the flight being conducted.
Approach & Departure - Runway 27
This is the most frequently used runway given that prevalent winds at Kilkenny are from the west. Aircraft normally take-off and land on the runway mostly favouring into the wind. Aircraft landing on Runway 27 approach from the city side of the aerodrome (located 2km east).
Landing - Runway 27
Allows a straight in approach for 1.46km to Runway 27 runway threshold clear of overflying any private residence. This is considered a clear path for the purpose of noise-abatement.
Departure - Runway 27
Allows a straight climb out for 2.16km from Runway 27 threshold before overflying the nearest residence. This is considered a clear path for the purpose of noise-abatement.
Approach & Departure - Runway 09
The approach to land on Runway 09 provides ample clear pathway almost entirely free of any private residence. The aerodrome has 300m length of open and clear grass on this approach. This forms part of the aerodrome property and ensures no obstacles will ever penetrate this approach path.
Landing - Runway 09
Allows a straight in approach clear of overflying private residence for 2.16km to Runway 09 threshold. This is considered a clear path for the purpose of noise-abatement.
Departure - Runway 09
Allows a climbout for 1.46km from Runway 27 runway clear of overflying any private residence. This is considered a clear path for the purpose of noise-abatement.
Approach Runway 27/ Departure - Runway 09
Approach Runway 09/ Departure - Runway 27
Fly-Neighborly Standard Policy
During appropriate weather conditions the preferred runway is runway 27.
Propellers generate as much noise as engines; flying with the lowest RPM setting will reduce aircraft noise (AOPA).
On take off gain altitude as quickly as possible without compromising safety (AOPA).
Avoid flying over built up areas.
Consider neighbours on the ground who might not enjoy aircraft noises as much as a pilot would.
