keep Air Navigation Regulations (Amendment)
Air Navigation Regulations (Amendment) registered 2005-01-01 - Amendment to the primary Air Navigation Regulations governing airspace usage, flight procedures, and aviation safety coordination in Australia.
Provisional assessment: aviation navigation regulations address genuine safety externalities and coordination problems (airspace management, collision avoidance) that are difficult to address through market mechanisms alone. Without the specific text I cannot identify provisions for deletion, though any future review should scrutinize barriers to entry for smaller operators and compliance costs that may impede competition.
