and\n    (b) how the information is to be given; and\n    (c) that the operator must comply with the notice within 30 days after receiving the notice.\n  (3) The operator of an aircraft commits an offence if:\n    (a) the operator is subject to a requirement under subsection (1);

the Secretary may delegate these powers to senior APS employees (sections 15–17).\n- Exceptions: Victoria Police use and aircraft engaged in defined emergencies are permitted to operate despite the bans (section 14).\n\n**Why it matters and what behaviour it changes\n\n- It limits night-time operations and heavier aircraft at Essendon Fields, so operators will generally avoid scheduling flights that start or end within the curfew window and will avoid using Essendon as a planned alternate if the flight ends during curfew (sections 7–10).\n- Operators of small or propeller-driven aircraft who want to operate during curfew must hold valid noise certificates and, for some types, meet numerical noise limits (sections 12–13 and cross-reference to the Air Navigation (Aircraft Noise) Regulations 2018).\n- Operators must file flight plans for any movement during curfew and be ready to produce information if the Secretary requests it; failure carries penalty units (sections 10, 16).\n- The Secretary’s dispensation power introduces an administrative route for one-off exceptions; operators who expect to rely on that route will incur application and post-event reporting obligations (section 15).\n\n**Penalty and evidential rules\n\n- Key offences carry penalties expressed in penalty units (commonly 50 penalty units for unlawful take-offs/landings and flight-plan failures, and 10 penalty units for failures to comply with dispensation reporting or information notices) (sections 6, 8, 9, 10, 15, 16).\n- There is a strict liability offence if a scheduled flight names Essendon as an alternate airport and the flight is scheduled to end during curfew (section 9).\n- The instrument notes that defendants bear an evidential burden in relation to some matters — referencing the Criminal Code evidential-burden provision (see notes to sections 6, 8, 10).\n\n**Stated purpose and how the instrument achieves it\n\n- The instrument operates mechanistically to limit noise and disturbance during night hours and to restrict larger aircraft operations at Essendon Fields by: imposing a curfew window (s7–8), banning heavy aircraft (s6), limiting alternate-airport use (s9), imposing flight-plan and noise-certificate requirements (s10, 12–13), and providing narrow administrative exceptions (s11, 14–15).\n\n**Costs, incentives and trade-offs (practical effects)\n\n- Who pays: aircraft operators bear the compliance costs — adjusting schedules, rerouting to other airports, obtaining and maintaining noise certificates, submitting flight plans, and responding to information notices (sections 10, 12, 16).\n- Who decides: the Secretary (and any delegate) controls individual dispensations and information requests, creating administrative discretion that operators must manage (sections 15–17).\n- Competitive effects: scheduled public transport operators are expressly constrained (definition of \"regular public transport operation\" and restrictions in s6(2)(b)(iii)), which may direct scheduled regional airline capacity away from Essendon and toward other airports.\n- Compliance burden and implementation risk: numerical noise limits, evidential burdens, and strict-liability provisions increase documentary and operational risk for operators. The Secretary’s discretion to grant one-off dispensations reduces predictability for commercial planning (sections 9, 12, 15).\n- Concentrated benefits vs diffuse costs: the instrument concentrates benefits (reduced night noise/disturbance for nearby residents) while costs (operational disruption, potential increased fuel/time for diversions) are dispersed across operators and passengers.\n- Possible substitution effects: operators unable to use Essendon during curfew or with heavier aircraft may shift flights to other airports or different times, affecting traffic patterns and commercial choices.\n\n**Implementation and oversight notes\n\n- The Secretary must keep a record of any dispensation and reasons; applicants must produce a written statement after using a dispensation (section 15(6)–(7)).\n- Delegation is allowed only to senior APS employees and delegates must follow any Secretary directions (section 17). These provisions create an administrative chain while preserving centralized accountability.\n\n(References in parentheses are to the numbered sections of the instrument cited above.)"}},"importantCases":[],"_links":{"self":"/api/acts/air-navigation-essendon-fields-airport-regulations-2018","history":"/api/acts/air-navigation-essendon-fields-airport-regulations-2018/history","analysis":"/api/acts/air-navigation-essendon-fields-airport-regulations-2018/analysis","conflicts":"/api/acts/air-navigation-essendon-fields-airport-regulations-2018/conflicts","importantCases":"/api/acts/air-navigation-essendon-fields-airport-regulations-2018/important-cases","documents":"/api/acts/air-navigation-essendon-fields-airport-regulations-2018/documents"}}
