Here is the list of cheap airfare san diego wiki pages: strategies employ three principal types of interventions: ground holding , i.e., intentionally delaying an aircraft�s takeoff for a specified amount of time; rerouting , i.e., changing or restructuring some flight routes to modify the distribution of traffic flows; and metering , i.e., controlling the rate at which traffic crosses some specified spatial boundaries by adjusting the spacing between aircraft. Ground holds are typically employed when a serious overload is expected at a specific airport and are imposed on aircraft with that destination. Rerouting is often used when convective weather is blocking a route or if there is a traffic overload in a specific sector. Metering is used to manage aircraft flow rates into specific sectors. In recent years, the ATCSCC in the USA has increasingly coordinated its interventions with airlines, airports and ATC facilities, in a process which is known as collaborative decision making (CDM). The objective of CDM is to share information among stake- holders and thus provide a �common knowledge base� on which to base TFM decisions. Prior to CDM, the CFMU would often base its interventions on obsolete information. For example, when a major snowstorm reduced capacity at hub airports, such as Chicago O�Hare, the airlines would proactively cancel many flights. However, the CFMU did not have this information and thus could not assess accurately the extent of the projected overload. In the absence of information about flight cancellations, the overload would typically be overestimated and the CFMU would often impose unnecessary restrictions on traffic. To optimize the performance of the TFM system, CDM employs a variety of information-sharing techniques including a web-based Flight Schedule Monitor, periodic teleconferences with the airlines, and rescheduling methods aimed at ensuring fairness in the allocation of the limited available capacity among the airlines and other airspace users. A detailed overview of the air traffic flow management systems in the USA and in Europe, as well as a description of how CDM currently operates in the USA, can be found in Ball et al . (2007).
