Introduction A growing trend is that the administration structures in the airports have been changing significantly in several parts of the world. A major transformation in the industry is changing of airports from being public or government utilities. There has been a rise in cases where private individuals own airports as well. The government has the powers to introduce regulations that control both private and public airports. These regulations are meant to determine the quality, price and the quantity of the airports and to specify the traffic control system, which is an issue of concern between the academics and the practitioners (Sydney Airport Carparks 2010). Sydney Airport being the busiest airport in terms of cargo movement and passengers both internationally and nationally, the Australian government had to introduce rules and regulations to monitor its operation. The regulations came in terms of curfews and control of the number of aircraft landing or setting off from the airport. The government had good intentions to both the natives, passengers and everybody in general. Without regulation, the airport is most likely to be mismanaged with rising cases of congestion. That can cause delays to both the cargo and passengers. It also prevents the likelihood of occurrence of accidents in the airport. In spite of the reduced freedom, the ATC has always remained the chief organization. The slow growth of the airport in terms of market penetration and share acquisition results from the monopolistic nature in the creation of this service. The cost of controlling flights tends to lower as the Area Control Centre covers. The economists argue that if the market was to be opened to all, the charges incurred in controlling the flights will considerably decrease (Sydney Airport Carparks 2010). The rationale for the introduction of the night curfew and aircraft number limitations The curfew that was introduced at the Sydney airport was not meant to stop all flights from landing at the airport during the night. Instead, it limited the number of flights that took off or landed at the airport. They realized this objective by limiting the types of aircrafts that used the port, the runway that was functional and the volume of flights that were permitted into the port. The passenger plane flights were not permitted. The planes that had small propellers and those that met noise and weight requirements were allowed during the night. This made possible the movement of critical freight such as fresh food and mails. Because of the time disparity with the northern hemisphere, a few international jet flights were permitted from between 5am to 6am. During the embargo, aircrafts used the Botany Bay. A maximum of not more than 15 aircrafts was allowed per an hour. In case of emergencies for example, air ambulance, mechanical malfunctioning or search and rescue, the curfew did not apply. The curfew was a legal action and failure to adhere was a criminal offence punishable in the courts of law. Fines not exceeding $550,000 were charged as a penalty. One of the reasons for the main reasons for the development the night curfew was the noise impact on the natives. Despite of the economic value of the airport, the government had to look further into the dangers and uncomforting environment
