Proposed future measures
15 Degree offset approach to runway 35
The provision of a 15-degree offset approach to Runway 35 in visual conditions has been proposed. This is in addition to the current curved or RNP approach currently flown by B737NG aircraft. This proposed Noise Abatement measure could provide noise amenity to Jerrabomberra, as arriving aircraft would fly over rural land west of built-up areas. GPS-based technology such as RNP will be able to expand these opportunities, possibly allowing for the offset approach to join the extended Runway centreline closer to the airport and allowing use of an offset approach in instrument (non-visual) conditions.
Runway 17 as preferred runway
Runway 17 is already nominated as preferred Runway at Canberra Airport for arrivals after 8pm and before 6am. It is proposed that this is increased to cover all times of day and night, when weather conditions permit.
This measure would provide significant noise abatement to the residents of Jerrabomberra as arriving aircraft would pass over rural land to the north of the airport and departing aircraft use the offset departure flight path and pass over rural land at Tralee and Environa rather than over Jerrabomberra.
Future GPS opportunities
Global Positioning System (GPS) technology is expected to revolutionise airport arrival and departure flight path procedures in future years, replacing old Instrument Landing System (ILS) and other technology. This is already evidenced by the growing use of RNP technology by aircraft at Canberra Airport. Full precision GPS enabling instrument landing being progressively introduced around Canberra International Airport. Offset approach opportunities are being introduced to provide noise respite to existing residents by shifting noise away from Jerrabomberra to the rural areas of Tralee and Environa.
