Sydney Airport CAP is essential - don’t change it Kerrie Mather, CEO of Sydney Airport stated in Sydney Morning Herald of 16 February, that Sydney Airport is seeking to “modernise these 20-year-old [restrictions]" and expand the flight movement cap to cater for increased flight movements (more flights per hour) citing the current era of quieter planes as justification.Planes are becoming “quieter” but bigger or more powerful so the difference in noise is not discernible to the human ear. The Airbus A380 mooted as a “quiet plane” is still the second most noisy plane using Sydney Airport. Therefore, there is no valid argument to increase the CAP Sydney Airport based on quieter planes. No Aircraft Noise believes the flight movement CAP should NOT be expanded as it is essential for a reasonable life in Sydney and would spell the end of noise sharing throughout Sydney returning Sydney to the heavily concentrated flight paths. The noise intensity and frequency of concentrated flight paths resulted in the federal government recognising the need for operating constraints on Sydney Airport’s operations. This resulted in the Government implementing constraints in terms of the hours of operation (curfew), the frequency of movements (flight CAP) and access to Sydney Airport for regional planes. Flights to Sydney Airport overfly the most densely populated areas of Sydney and constraints are essential to the quality of life of the residents of Sydney, so any change impacts many people by reducing their quality of life with increasing noise.The noise from increasing flight frequency is currently a problem and any increases in the CAP would increase aircraft noise and require additional noise insulation in a number of Sydney suburbs to meet noise standards which is not included in the Sydney Airport proposal.Using every technique in their legal and lobbying portfolio to impede and or minimise Western Sydney Airport is monopolistic behaviour by Sydney Airport. They are wanting to squeeze more and more capacity and profit out of Sydney Airport without funding the construction costs of building Western Sydney Airport. Their increasing the CAP proposal would undermine the viability of the Western Sydney Airport when it becomes operational in 2026.It should be noted that Sydney Airport has the first right of refusal to construct and operate Western Sydney Airport, thus their behaviour is either impeding the construction of Western Sydney Airport or to make it unviable for another operator. The timing of this CAP proposal is purely profit driven and monopolistic. Sydney Airport’s proposal to increase flights beyond the CAP should NOT be allowed, it would result in unbearable increase of aircraft noise and the end of noise sharing within Sydney.
