Sydney Airport Noise Abatement Procedure Overview

A Noise Abatement Procedure (NAP) is a procedure designed to reduce the impact of aircraft noise on the community.

Airservices Australia has the following NAP in place at Sydney Airport:

LTOP Statistics provide information on noise sharing for Sydney Airport. Further NAP reporting is under development to compliment this information and will be available in 2026.

It is important to note that NAPs are not mandatory; ATC and pilots apply the NAPs whenever possible. Pilots and ATC will determine when critical operational requirements override the use of NAPs.

The overview below provides monthly movement numbers, runway end usage, and the types of aircraft operating at Sydney airport.

Note: Due to rounding, percentage values may not sum to exactly 100.0%. Minor discrepancies of up to ±1% are expected and do not indicate any errors in the underlying absolute figures, which remain accurate and unaffected.

Adelaide Airport NAP 2: Preferred Runway Use

The NAP lists the preferred runways during daytime hours as:

Priority 1: Arriving Runway 05/ Runway 23 and departing Runway 23 

Priority 2: Arriving Runway 05 and departing Runway 05/ Runway 23

Priority 3: Arriving Runway 12/ Runway 30 and departing Runway 30

Priority 4: Arriving Runway 12 and departing Runway 12/ Runway 30

Note: Non-jet aircraft under 32,000 kg can use any runway between 7am and 9pm local time

The following NAPs are not able to be reported on by Airservices Australia as we do not have ready access to the required data:          

  • 2.3: Jet aircraft noise abatement departure procedures

Adelaide’s seasonal wind patterns affect usage of the different runways. The prevailing wind is from the south for most of the year which results in aircraft arriving and departing towards the ocean most often using Runway 23. During the cooler months, aircraft arrive over the water and depart towards the city using Runway 05 more often, as the winds tend to be from the north.

Between 6am and 11pm the preferred runway is Runway 23, followed by Runway 05 as a second preference. This keeps departures, which are generally louder than arrivals, over water. If the main Runway 23/05 is not available, the preferred runway is the short cross Runway 30, and the second preference is Runway 12.

During the daytime period (6am-11pm local):

Priority 1:

Arriving Runway 05 or Runway 23, departing Runway 23

Priority 2:

Arriving Runway 05, departing Runway 05 or Runway 23

Priority 3:

Arriving Runway 12 or Runway 30, departing Runway 30

Priority 4:

Arriving Runway 12, departing Runway 12 or Runway 30

The report below provides the percentage use for each operating mode during daytime periods for each month (hover over each day in the column graph and the mode, the number of movements and the percentage use on that day will appear). “Other Operations” refers to modes used when preferred modes are not available, due to things like runway works, adverse weather and emergency situations.

The report is best viewed in full screen mode.

Note: Due to rounding, percentage values may not sum to exactly 100.0%. Minor discrepancies of up to ±0.1% are expected and do not indicate any errors in the underlying absolute figures, which remain accurate and unaffected.

Hobart Airport Noise Abatement Procedure Overview

A Noise Abatement Procedure (NAP) is a procedure designed to reduce the impact of aircraft noise on the community.

NAP reporting for this airport will be released in the fourth week of the month for the previous month.

We will commence reporting on preferred flight path use, including use of the NAP for arrivals to Runway 30, in coming months. In the meantime, we have provided an overview of runway end use and the most common aircraft that operate at Hobart Airport.

Reporting is now available for:

1. Preferred Flight Paths

2/3. Arrivals During and Outside Tower Hours

It is important to note that NAPs are not mandatory; Air Traffic Control (ATC) and pilots apply the NAPs whenever possible. ATC and pilots will determine when critical operational requirements override the use of NAPs.

The overview below provides monthly movement numbers, runway end usage, and the types of aircraft operating at Hobart airport.

Note: Due to rounding, percentage values may not sum to exactly 100.0%. Minor discrepancies of up to ±1% are expected and do not indicate any errors in the underlying absolute figures, which remain accurate and unaffected.

Hobart Airport NAP 1: Preferred Flight Paths

The NAP lists the preferred flight paths as::

1. Preferred Flight Paths

Arrivals

  • (1.a) Arrivals: Expect processing via published STAR.

Departures

  • (1.b) Departures: Expect processing via published SID.

Adherence with this procedure is reported below. SID operations are reported up to 10,000ft adherence.

2. Arriving Aircraft During Approach Hours of Operation

  • 2.a: Arriving Runway 12: No specific procedures apply.
  • 2.b: Arriving Runway 30:
    • Before 08:00 – Aircraft will use the RNAV approach.
    • From 08:00 to 14:00 – No special procedures apply.
    • After 14:00 – Aircraft will again use the RNAV approach.
  • 2.c: Departing Runway 12 and 30: Refer to 1.b.
  • 2.d: Arrivals VOR approaches – currently specific VOR approach data is not available.

Adherence with the 2.b procedure is reported below.

3. Arriving Aircraft Outside Approach Hours of Operation

  • 3.a: Arriving Runway 12: No specific procedures apply.
  • 3.b: Arriving Runway 30: Refer to 2.b.
  • 3.c: Departing Runway 12 and 30: No specific procedures apply.
  • 3.d: Arrivals VOR approaches – currently specific VOR approach data is not available.

The report is best viewed in full screen mode.

Note: Due to rounding, percentage values may not sum to exactly 100.0%. Minor discrepancies of up to ±1% are expected and do not indicate any errors in the underlying absolute figures, which remain accurate and unaffected.

Canberra Airport NAP 1: Preferred Runway Use

The NAP lists the preferred runways during daytime hours as:

Priority 1: Arriving Runway 35/ Runway 17/ Runway 30 and departing Runway 35

Priority 2: Arriving Runway 12 and departing Runway 17

Note: Daytime NAPs apply between 7am and 8pm local time

The NAP lists the preferred runways during night-time hours as:

Priority 1: Arriving Runway 17 and departing Runway 35

Priority 2: Arriving Runway 35/ Runway 30 and departing Runway 17

Priority 3: Arriving Runway 12 and departing Runway 30/ Runway 12

Note: Night-time NAPs apply between 8pm and 7am local time

A Noise Abatement Area applies to most areas of Canberra and Queanbeyan, however, some exemptions apply if it is not possible for aircraft to avoid the area. Smaller propeller aircraft are permitted to fly in this area.

The NAP priorities seek to avoid the Noise Abatement Area and concentrate noise over less densely populated areas to the north of the airport. Canberra’s seasonal wind patterns support arrivals and departures to the north on Runway 35 more than 70 percent of the time. Arrivals and departures towards the south on Runway 17 tend to be used more frequently in the warmer months than at other times, but this does vary. The shorter cross runway is used mainly by smaller propeller aircraft.

During the daytime period (7am-8pm local):

Priority 1.1: (Equal)

Arriving Runway 30 or Runway 35, departing Runway 35

Priority 1.2: (Equal)

Arriving Runway 17 and departing Runway 35

Priority 2:

Arriving Runway 12 and departing Runway 17

Priority 3:

Arriving Runway 12 or Runway 17 or Runway 30 or Runway 35, departing Runway 12 or Runway 30

During the nighttime period (8pm-7am local):

Priority 1:

Arriving Runway 17, departing Runway 35

Priority 2.1: (Equal)

Arriving Runway 35, departing Runway 17

Priority 2.2: (Equal)

Arriving Runway 30, departing Runway 17

Priority 3:

Arriving Runway 12, departing Runway 12 or Runway 30

*Priority 3 applies only to departures

The report below provides the percentage use for each operating mode during daytime and night-time periods for each month and a daily breakdown across the month (hover over each day in the column graph and the mode, the number of movements and the percentage use on that day will appear). “Other Operations” refers to modes used when preferred modes are not available, due to things like runway works, adverse weather and emergency situations.

The report is best viewed in full screen mode.

Note: A discrepancy was identified in the May 2025 data and has since been corrected. The report now reflects the most accurate and up-to-date figures.

Note: Due to rounding, percentage values may not sum to exactly 100.0%. Minor discrepancies of up to ±0.1% are expected and do not indicate any errors in the underlying absolute figures, which remain accurate and unaffected.
