Airservices manages enquiries and complaints about aircraft noise and operations through the Noise Complaints and Information Service (NCIS). The information below is collected by the NCIS for the purpose of complaint management, analysis of issues and identification of causal factors. For this reason we refer to ‘complainants’ and ‘issues’. Complainants are people who contacted the NCIS. While some people submitted enquiries or comments rather than complaints, all are referred to as “complainants”. Issues are the primary concern they raised.
There were 42 complainants in quarter three 2018, which is a decrease from 53 complainants in quarter two. This is also a decrease from quarter three 2017 which recorded 67 complainants.
The issue of Standard flight path movements continues to be the main issue raised this quarter, as can be seen in Chart 1 below affecting 71 percent of complainants.
Chart 1: Issues raised in quarters one, two and three 2018
Use of Runway 01 has increased this quarter compared to the previous quarters, due to the prevailing winds. More information can be found on runway selection in our Factsheet. Consequently there has been an increase in complainant concerns regarding Runway 01 operations this quarter and a corresponding decline in complainant concerns regarding Runway 19 operations.
Chart 2 below provides a breakdown of the Standard flight path movements issue relating to the runway in use, and provides a comparison with quarters one and two 2018.
Chart 2: Breakdown of Standard flight path issue and runway use
Runway 01 use historically increases in the warmer months, and Runway 19 use decreases.
The issue of Night movements was raised by 24 percent of complainants in quarter three, with 60 percent of these complainants raising concerns with Runway 19 operations.
Complainants were recorded from 30 separate suburbs. The suburbs with the most complainants were Ferny Hills and Morningside with four complainants each, Coorparoo with three complainants, and Highgate Hill, Kedron, Nundah, and Wynnum with two complainants each.
Ferny Hills complainants were predominately concerned with Runway 19 departures, including operations at night. Morningside complainants were concerned with both Runway 19 departures as well as Runway 01 arrivals. Both suburbs, Ferny Hills and Morningside, are impacted by both Runway 01 arrivals and Runway 19 departures.
Coorparoo residents raised concerns over Runway 01 arrivals.
The residents of Highgate Hill, Kedron, Nundah, and Wynnum raised the issue of Standard flight path movements and Night movements with Runway 19 departures the main concern.
Twenty-three suburbs recorded a single complainant.
There were 53 complainants in quarter two 2018, which is a slight decrease from 54 complainants in quarter one 2018. This is also a decrease from quarter two 2017 which recorded 65 complainants.
The issue of Standard flight path movements continues to be the main issue raised this quarter affecting 79 percent of complainants.
Chart 1 below provides a breakdown of the Standard flight path movements issue relating to the runway in use, and provides a comparison to quarter one 2018.
Chart 1: Breakdown of Standard flight path issue and runway use
Runway 19 continued to be used to the greatest extent this quarter, and this is reflected in the number of complainants; overall 60 percent of complainants where affected by Runway 19 operations.
The issue of Night movements was raised by 22 percent of complainants, the majority also concerned with Runway 19 operations. It is important to note that a single complainant may raise one or more than one issue.
Complainants came from 35 separate suburbs. The suburbs with the most complainants were Norman Park with six complainants, and Coorparoo, Hemmant, and Seven Hills with four complainants each.
Twenty-seven suburbs recorded a single complainant.
Norman Park, Coorparoo and Hemmant residents were mainly concerned with the issue of Standard flight path movements relating to Runway 19 operations. Several residents were affected by night operations.
Seven Hills residents were also affected by Standard flight path movements, however, 50 percent of these complainants were affected by Runway 01 arrivals.
There were 54 complainants for the first quarter of 2018, which is a decrease from 64 complainants in the fourth quarter of 2017. This is significantly below the number of complainants in the first quarter of 2017 which was 83 complainants.
The issue of Standard flight path movements continues to be the main issue to be raised. This is consistent with the previous 12 months. The issue of Night movements also continues to be second most prevalent issue raised during this period. Chart 1 below shows the number of complainants raising each issue in the first quarter.
Chart 1: Issues and complainant numbers
The use of Runway 19 has increased in this quarter. This is a result of the normal seasonal wind cycle at the airport, and this is reflected in an increase in complainants raising concerns related to Runway 19 operations.
The issue of Standard flight path movements was raised by 70 percent of complainants, with 55 percent of these complainants concerned with departing traffic from Runway 19. Night movements was raised as an issue by 28 percent of complainants with 60 percent of these complainants concerned with departing traffic from Runway 19.
Complainants came from 37 separate suburbs. The suburbs with the most complainants were Coorparoo, Ferny Hills and Morningside, each with four complainants. Twenty-six suburbs recorded a single complainant.
Ferny Hills’ complainants were all concerned with aircraft departing from Runway 19.
Coorparoo and Morningside complainants were concerned with both Runway 19 Departures and Runway 01 Arrivals, reflecting that these suburbs are under both the arrival flight path for Runway 01 and a departure flight path off Runway 19.
There were 228 individual complainants for the year which is a decrease from 266 complainants in 2016.
As shown in Chart 1 below, the main issues raised for 2017 were Standard flight path movements and Night movements. The Standard flight path movements issue was raised by 187 complainants and Night movements was raised as an issue by 38 complainants in 2017.
Chart 1: Issues and complainant numbers
Standard flight path movements
The majority of complainants affected by the issue of Standard flight path movements were concerned with either Runway 01 Arrivals (46 percent) or Runway 19 Departures (35 percent). Both of these flight paths track over the city of Brisbane.
Generally Runway 01 arrival movements are higher in the warmer months whereas Runway 19 departure movements are higher in the cooler months. This is due to the way seasonal wind patterns affect runway usage, and can be seen in Chart 2 below.
Chart 2: Runway usage for Brisbane Airport 2015 to 2017
Reciprocal runway operations are used at Brisbane Airport in the night period whenever possible. This has the aircraft landing and departing over Moreton Bay. However at times this is not possible due to unsuitable weather and/or traffic conditions, resulting in aircraft flying over suburbs.
Runway 19 Departures in the night period was nominated by more than half of the complainants who raised the issue of Night movements, while Runway 01 Arrivals was nominated by around one-third of these complainants.
Chart 3: Runways nominated in Night movement issue
Complainants from 97 separate suburbs raised issues in 2017. The suburbs with the most complainants were Coorparoo with 17 complainants, Morningside with 11 complainants, Tingalpa with nine complainants, and Norman Park with eight complainants. Cannon Hill, Greenslopes, Paddington, Seven Hills and Sheldon all had seven complainants.
Coorparoo is located under the Runway 01 arrival flight path, and a section of the suburb is also overflown by some departures off Runway 19. The majority of complainants from this suburb raised concerns about Runway 01 arrivals.
Morningside is closer to the airport and is overflown by both Runway 01 arrivals and by Runway 19 departures. Most complainants from this suburb were concerned with Runway 19 departures.
Tingalpa is overflown by aircraft with destinations to the south departing off Runway 19. All complainants from this suburb were concerned with departures from Runway 19 with 66 percent raising the issue of Night movements.
Paddington is under the Runway 19 departure path for aircraft tracking to the north and northwest. All but one of the complainants from this suburb were concerned with these departures.
Norman Park, Cannon Hill, Greenslopes, Sheldon and Seven Hills are all under the arrival flight path for Runway 01.
Sixty suburbs recorded a single complainant.
Chart 4 below shows the eleven suburbs with the most complainants for 2017 and the comparison of numbers of complainants for each of those suburbs in 2016.
Chart 4: Suburb and complainant comparison 2017 and 2016
There were 64 complainants for quarter four 2017. This is a slight decrease from 67 complainants in the previous quarter. Some complainants raised more than one issue in the quarter.
As shown in Chart 1 below the main issues raised in quarter four were Standard flight path movements and Night movements.
Chart 1: Issues and complainant numbers
The issue of Standard flight path movements was raised by 78 percent of complainants, with 62 percent of these concerned with Runway 01 Arrival operations. Runway 19 Departures were raised by 24 percent of the complainants raising the issue of Standard flight path movements. This can be seen in Chart 2 below.
Chart 2: Runway directions associated with Standard flight path issues
The issue of Night movements was raised by 17 percent of complainants overall, with Runway 01 Arrivals and Runway 19 Departures each being of concern to 36 percent of these complainants. Runway 01 Arrival and Runway 19 Departure flight paths both go over the populated areas of Brisbane.
The issue of unusual movements was raised by complainants concerned with either aircraft diverting around bad weather or taken off the normal route due to traffic management requirements.
Complainants from 41 suburbs raised issues in quarter four of 2017.
The suburbs recording the most complainants were Coorparoo with five, and Canon Hill, Morningside, and Norman Park with four complainants each. All these suburbs are under both Runway 01 Arrivals and Runway 19 Departures flight paths.
Thirty suburbs recorded a single complainant.
There were 67 complainants for quarter three 2017. This is a slight increase from 65 complainants in the previous quarter but a decrease compared to quarter three of 2016, where there were 85 complainants. Some complainants raised more than one issue in the quarter.
There have been 183 individual complainants for the year to date.
Eighty-four percent of the issues raised by complainants in quarter three were regarding standard flight path movements as chart 1, below, shows,
Chart 1: Issues and number of complainants reporting them
The NCIS continues to refine how issues are classified and applied. We have recently decided to classify all complaints regarding movements that are tracking on the relevant flight path and within the normal altitudes as Standard flight path movements. In our reporting to the community this will provide greater clarity about what can be expected in the normal course of operations at the airport. Additionally the issue of Unusual Movements will be used for commercial aircraft operating outside their usual flight paths at major airports. Examples of unusual movements include, weather diversions, traffic management, radar departures, direct tracking and missed approaches.
The Night Movements category has been expanded beyond the previous 11pm – 6am hours to cover complainants who advise the NCIS that they have been disturbed by air traffic at any hour of the night.
The reason for these changes is to better reflect normal and unusual operations in our reporting and to allow us to more efficiently identify whether or not there are any noise mitigation opportunities available. In most cases at major airports, there is little that can be achieved for any standard flight paths.
The majority of complainants raising flight path issues were concerned with Runway 01 arrivals as shown in chart 2, below. The use of Runway 01 historically rises from July and this was the case for 2017.
Chart 2: Runway directions associated with flight path issues
Complainants from 39 suburbs raised issues in the third quarter of 2017. Fourteen suburbs recorded two or more complainants.
The suburbs recording the most complainants were Coorparoo with 11 complainants, Greenslopes with six complainants, and Morningside, Seven Hills, Sheldon and Tarragindi with three complainants each.
The majority of residents from all suburbs were concerned with standard flight path movements, and were affected by Runway 01 arrivals.
Additionally six residents from Greenslopes, Morningside and Tarragindi were disturbed by Night Movements on Runway 01.
There were 65 complainants for the quarter. This is a decrease from 83 complainants in the previous quarter and below quarter two of 2016, where there were 84 complainants. Some complainants raised more than one issue in the quarter.
There have been 133 individual complainants for the year to date. This means that, of the 65 complainants who contacted us in quarter two, 50 were complaining for the first time this year and 15 complained in quarter one also.
Seventy-two percent of the issues raised by complainants in quarter two were about flight paths including concerns about increased frequency of use, perceptions something had changed, and the altitudes of aircraft. A further twenty-five percent were about night-time movements.
Chart 1: Issues, quarter one
The majority of complainants raising flight path issues were concerned with Runway 19 departures as shown in Chart 2. The use of Runway 19 historically rises between February and July and this was the case for 2017, with a sharp rise in the use of Runway 19 in April and a corresponding decrease in the use of Runway 01. This is illustrated in the “Operations by runway” charts for quarters one and two on the Runways page.
Chart 2: Runway directions associated with flight path issues
Concerns about night movements were related to restricted use of reciprocal runway operations at night during the first half of the quarter due to required works. These works finished in early May.
Complainants from 39 suburbs raised issues in the second quarter of 2017. Twenty-seven suburbs had one complainant each. Twelve suburbs had two or more complainants.
The suburbs recording the most complainants were Tingalpa with six complainants, Ferny Hills with five complainants, and Morningside and Sheldon with four complainants each.
Issues raised by Tingalpa, Ferny Hills and Morningside residents were primarily about Runway 19 departures, including night movements. Sheldon residents are affected by Runway 01 arrivals (see Q1 2017).
There were 83 complainants during the first quarter of 2017, an increase from 77 complainants in the previous quarter but below quarter one in 2016 when there were 94.
Some complainants raised more than one issue in the quarter, meaning that some complainants are double-counted in the figures in the next section.
Bad weather in March resulted in the need for some aircraft to divert from the usual flight paths in order to avoid storm cells. Fifteen complainants raised the issue of aircraft flying unusual paths, including three complainants from Ascot, four from Clayfield and one each from Wooloowin and Hendra. All these suburbs were affected when jets diverted over their area by turning north-west shortly after departure to avoid storms and lightning to the south-east.
Eighty-four complainants were concerned about flight path issues including the perception that something had changed, increased frequency of movements, night movements and altitudes. Twenty-six were concerned about departures from Runway 19 and 33 were concerned about arrivals to Runway 01 as shown in chart 1.
Chart 1: Runway directions associated with flight path issues
In February and March usage of Runway 01 was above the level normally expected. Looking at usage over the last five years, February usage in 2017 was exceeded only by that in 2014 and March usage in 2017 was exceeded only in 2014 and 2015. If the typical seasonal pattern holds, as the cooler weather begins usage of Runway 01 will drop and Runway 19 will increase.
In quarter one complainants came from 49 separate suburbs.
The suburbs recording the most complainants were Ascot with five complainants and Sheldon, Clayfield and Coorparoo with four complainants each. Ascot and Clayfield were affected by weather diversions as discussed above.
Sheldon is under one of the arrival paths for Runway 01, with aircraft overflying the suburb generally between 3000 – 5000 feet. All the complainants from the suburb were concerned with Runway 01 arrivals.
Coorparoo is mainly affected by arrivals for Runway 01 but is also overflown by some of the jet departures off Runway 19 which are tracking to destinations to the west and north.
Four suburbs, Tingalpa, Ferny Hills, Seven Hills and Carindale all had three complainants each, with another 13 suburbs having two complainants. A further 28 suburbs had one complainant each.
In 2016 a total of 266 complainants raised 277 issues, which shows that a number of complainants raised more than one issue each.
237 complainants raised issues associated with flight paths. Concerns included increased frequency of movements, a perception that something had changed such as the flight path or altitudes, or a desire for a flight path to be moved.
The concerns of 112 complainants could be related to arrivals to Runway 01 and for 84 complainants to departures from Runway 19.
A total of 97 suburbs across the Brisbane basin recorded at least one complainant. 45 suburbs, or nearly half, had one complainant only. 24 suburbs had two complainants, nine suburbs had three complainants and one suburb had four complainants.
There were 17 suburbs with five or more complainants. A number of these are affected by both arrivals and departures from the main runway, arrivals if the wind is northerly and departures if the wind direction is mainly southerly. These include Morningside (21 complainants), Coorparoo (19), Camp Hill (13), Greenslopes (8), Cannon Hill (6), Seven Hills (6) and Norman Park (5). Their proximity to the airport means that aircraft are quite low over these suburbs.
Arrivals to Runway 01 caused the most concern in quarter four. Increased use of Runway 01 at this time of year is the expected seasonal pattern.
This quarter complainants from 40 suburbs contacted the NCIS. More than half of these suburbs (24) had one complainant each. The suburb with the most complainants was Morningside with eight complainants, followed by Sheldon with seven and five from Moorooka. Coorparoo and Cannon Hill had four complainants each. A further three suburbs had three complainants and eight suburbs had two complainants.
Full runway closures on the main Runway 01/19 continued throughout the quarter from midnight to 5 am. The schedules of some international flights were adjusted to allow them to arrive or depart Brisbane Airport at a time when the main runway was operational as the shorter runway is not suitable for these aircraft.
Seasonal weather patterns meant that the use of Runway 19 began to decline over this quarter and the use of Runway 01 began to increase.
Most complainants concerned about Runway 01 arrivals raised the constant nature of aircraft movements when this path is used, and the sleep disturbance caused by aircraft between the hours of 11 pm and 6 am. From quarter four 2016, when complainants advise of an aircraft operating during night-time hours the issue will be recorded as “night movements” to enable better tracking of this concern.
Complainants and suburbs
There were 85 complainants in the third quarter which is consistent with the second quarter. Four complainants raised more than one issue. For the year-to-date there have been 215 unique (individual) complainants. Some complainants have complained in more than one quarter.
The suburbs with the most complainants for quarter three were Coorparoo (nine), Camp Hill (eight) and Sheldon (five).
Coorparoo and Camp Hill lie underneath the Instrument Landing System flight path for Runway 01 and are also affected by Runway 19 departures.
Chart: Coorparoo and Camp Hill issues
“YBBN” is the code for Brisbane Airport. 01 and 19 are runway directions.
Sheldon while also affected by aircraft arriving for Runway 01 is affected by flights that are able to accept a shortened flight path. This occurs in better weather conditions. These aircraft track over Sheldon to join the main approach path in the Morningside area. They are mostly domestic jets.
The percentage of complainants who were affected by the runway closures dropped to six per cent this quarter.
There were 26 suburbs with one complainant, eleven suburbs with two complainants, three suburbs with three complainants and one suburb with four complainants.
Scheduled maintenance works on the main runway required full closure of the runway between the hours of midnight and 5 am from 9 May. During this period all traffic had to use the shorter runway.
Historically Runway 19 use peaks in quarter two and this seasonal pattern held. However the number of aircraft movements on this runway remained lower than those recorded in quarter two from 2011 to 2014.
While Runway 19 use peaked this does not mean that Runway 01 was not used. Runway 01 arrivals continued to affect complainants from suburbs aligned with the runway. The most affected are under the Instrument Landing System approach. This is due to the requirement that aircraft align with the runway from a distance of 10 nautical miles out (around 18 kilometres).
Complainants concerned about use of Runway 19 and Runway 01 tended to characterise this as increased frequency, as a change of flight path or were unhappy about the location of the flight path.

“YBBN” is the airport code for Brisbane Airport. 01, 14 and 19 are runway directions.
Complainants and suburbs
There were 84 complainants during the second quarter. This is a slight decrease from quarter one. For the year-to-date there have been 155 “unique” or individual complainants. Some complainants have complained in both quarters.
Eight complainants (ten per cent of all complainants) were affected by the night-time closure of the main runway. These complainants resided in suburbs underneath the approach or departure path to the smaller runway such as Wynnum and Nudgee.
This quarter the suburbs with the most complainants were Tingalpa (seven) and Wakerley (five). These suburbs are adjacent to the departure path to the south-east of the Airport and were affected by the seasonal increase in departures from Runway 19. Aircraft using this flight path are departing for southern destinations such as Sydney, Melbourne and Adelaide. This flight path was slightly modified in 2014 and moved 200 metres to the west to maximise use of non-residential land. More information about the Runway 19 south-eastern departures realignment
Overall the majority of complainants this quarter were concerned about departures from Runway 19. There were four complainants from Morningside and three from Coorparoo. Thirteen suburbs had two complainants each and 32 suburbs had one complainant.
In January, use of Runway 01 was high due to northerly winds. In February and March the wind became predominantly southerly and as a result use of Runway 01 dropped and use of Runway 19 rose. This is a typical seasonal pattern for Brisbane, however complainants characterised it as an increase in frequency or as a change of flight path.
Complainants and suburbs
There were 94 complainants during the first quarter. The suburbs with the most complainants are all affected by both Runway 19 and Runway 01 traffic: Morningside (nine complainants), Greenslopes (six complainants) and Coorparoo (five complainants). Due to their proximity to the airport and their location in line with the runway, these suburbs will be affected by aircraft noise regardless of in which direction the main runway is used. However Morningside complainants were more concerned with Runway 19 use this quarter, while Greenslopes complainants were more likely to raise Runway 01 use.
Sheldon and Tingalpa had five complainants each. Tingalpa is affected primarily by departures from Runway 19 while Sheldon experiences arrivals to Runway 01.
Ashgrove, which is affected by departures from Runway 19, had four complainants. A further three suburbs had three complainants. Eleven suburbs had two complainants and 30 suburbs had one complainant.
