Residents near RAAF Base Pearce, north of Perth, may see an aircraft flying unusually low as the Civil Aviation Safety Authority (CASA) carries out important flight path safety checks.
The checks are being conducted by CASA to validate amended instrument approach procedures at RAAF Pearce to ensure they operate safely.
The checks of the new approach procedures are being carried out on Saturday, 5 April.
A twin-engine Beechcraft Baron aircraft, registration VH-MQM, will be used to carry out the safety checks within an area up to 10 kilometres from the aerodrome and several locations to the north and east.
Low-level flying is an essential part of the safety exercise, with the aircraft down as low as several hundred feet at times.
Local residents may notice an uncommon flying pattern, but this is to make sure obstacles are accurately marked on charts and no new obstacles exist. Obstacles can be towers, trees, masts or buildings that can be a danger to aircraft.
If poor weather or other factors do not allow the safety checks to go ahead on the planned days, they will be carried out as soon as possible.
