In accordance with the Civil Aviation Safety Authority (CASA) mandate that all aircraft operating under Instrument Flight Rules (IFR) are required to navigate primarily using satellite-based means and to ensure we continue to have the safest and most efficient air traffic management system possible, Airservices is re-designing arrival flight paths at some airports for aircraft flying on instrument flight rules.
According to recent ICAO and CASA requirements, the last few nautical miles of all final approaches to runways, including satellite based approaches, must be in a straight line with the runway to ensure the highest level of safety is achieved.
What is the change?
The non-directional beacon (ground-based navigation aid) at Archerfield Airport is being removed and replaced by satellite-based technology. As a result, an arrival flight path at Archerfield Airport is being re-aligned with the runway according to ICAO and CASA requirements.
When will the changes happen?
The arrival flight path will be available for suitably equipped operators from 26 May 2016.
How many aircraft use this flight path?
The flight path is expected to be used, on average, for 15 flights a day.
Will GNSS flight paths be different?
Arrival flight paths using GNSS are aligned with the runway, whenever possible, to reduce the operating complexity for the pilot. CASA has decided that GNSS arrival flight paths not aligned with the runway (offset) may be used only when siting or obstacles permit no other option. An ‘offset’ arrival flight path cannot be established as a noise abatement measure.
