SPECIAL flight safety checks are being carried out at eight NSW aerodromes in late February 2015, including Grafton.
The checks are being conducted for the Civil Aviation Safety Authority to make sure flight paths at the aerodromes continue to be safe.
NSW aerodromes being checked between 22 February and 1 March 2015 include Ballina, Coffs Harbour, Grafton, Kempsey, Lismore, Orange, Port Macquarie, Taree.
A series of low level flights will be undertaken at each aerodrome to check flight paths. This will ensure navigation aids are operational and not suffering interference, as well as looking for any new obstacles that could be a danger to aviation safety.
A twin-engine Cessna Conquest aircraft will be used to carry out the safety checks within an area up to 35 kilometres from the aerodromes. 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.
The Civil Aviation Safety Authority requires aerodrome flight path safety checks to be carried out every three years to maintain a high level of air safety at all aerodromes.
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.
CASA has contracted the operation of the special check flights out to Corporate Air, one of Australia's largest and longest established aviation services providers.
