Summary
Amendment to Air Navigation Regulations imposing aircraft noise restrictions, operating curfews, and noise-based operational limits at Australian airports. Likely establishes noise quotas, quiet periods, and compliance requirements for aircraft operators based on noise certification standards.
Reason
Aircraft noise regulations exemplify concentrated benefits with diffuse costs—residents near airports receive noise reduction benefits while the broader traveling public, airlines, and freight operators bear higher costs through curfews, restricted operations, and compliance burdens. Such regulations restrict voluntary transactions in air travel markets, inflate airfares by reducing competition and capacity, and impose property rights violations through regulatory coercion rather than negotiation. Environmental noise concerns, while legitimate, are more efficiently addressed through property rights mechanisms (easements, noise insulation subsidies) or zoning rather than operational restrictions on aircraft. The 2005 amendment likely tightened restrictions that already strangled airport capacity and competitiveness.
