To achieve the best aircraft safety outcomes for Adelaide, Airservices is working towards making Smart Tracking technology permanently available for all suitably equipped aircraft landing at Adelaide Airport. Implementation will be designed to maximise noise and emissions benefits. Smart Tracking has been trialled at Adelaide since 2009.
All Smart Tracking tracks at Adelaide are within existing long-standing flight paths (Proposed Smart Tracking routes – Adelaide).
As part of the evaluation of Smart Tracking at Adelaide, Airservices has analysed potential changes in aircraft noise distribution between 2011 and 2020 with and without Smart Tracking being used. The analysis assumes 85 per cent of jets will use Smart Tracking by 2020. The information below includes forecast growth in air traffic to 2020. However, the analysis shows only any difference in the noise impact of aircraft which could be attributed to Smart Tracking.
Approaches to Runway 23 (from the north east)
There are four Smart Tracking routes proposed to be made permanent for approaches to Runway 23.
- Track 1: Arrivals from the southwest to the southern runway. There will be no noticeable increase in overall noise levels. A few locations may experience noticeable increases or decreases in noise from the loudest aircraft – but where increase occur, the levels will not exceed 70 dB (the threshold beyond which noise is likely to impact on everyday activities). This track has a low level of use – the average number of flights is currently four a day with a maximum of ten on any given day.
- Track 2: Arrivals from the west to the southern runway. There may be some locations that could experience noticeable increases in noise from the loudest aircraft. However this track has a low level of use – the average number of flights is currently 3 a day with a maximum of 10 on any given day.
- Track 3: Arrivals using the overland straight-in approach to the southern runway. This track overlies the flight path which aircraft are generally required to use at night and during bad weather. There is expected to be a reduction in the number of aircraft using this track, as alternative tracks will be available. No changes in maximum noise levels are anticipated, and some areas are expected to experience a noticeable decrease in average noise levels.
- Track 4: Arrivals from the northeast to the southern runway. A few locations may experience noticeable increases or decreases in noise from the loudest aircraft – but where increase occur, the levels will not exceed 70 dB (the threshold beyond which noise is likely to impact on everyday activities).
Approaches to Runway 30 (from the south east)
- Track 5: Arrivals from the east to the western runway. A very low number of jet aircraft use this runway (0.3 a day on average) and there are 347 days per year when there are no jet arrivals. Therefore, there will be no noticeable noise impacts resulting from the implementation of Smart Tracking for this track.
Approaches to Runway 05 (from the south west)
The three Smart Tracking approaches to Runway 05 are almost exclusively over water to the south and west ofAdelaideairport and follow existing flight path corridors. The overland portions of the procedures overlay existing arrival paths.
- Track 6 – there may be a small decrease in noise from the loudest aircraft around Lonsdale.
- Tracks 7 and 8 are over water and will not cause any noticeable changes in noise levels.
