Abstract
Congestion is a problem at major airports in the world. Airports, especially high-traffic ones, tend to be the bottleneck in the air traffic control system. The problem that arises for the airspace planner is how to mitigate air congestion and its consequent delay, which causes increased cost for airlines and discomfort for passengers. Most congestion problems are fixed on the day of operations in a tactically manner using operational enhancements measures. Collaborative Trajectory Options Program (CTOP) aims to improve air traffic management (ATM) considering National Airspace System (NAS) users business goals, particularities faced by each flight and airspace restrictions, making this process more flexible and financially stable for those involved. In CTOP, airlines share their route preferences with the air control authority, combining delay and reroute. When CTOP is created, each airline might decide its strategy without knowledge of other airline’s flights. Current solutions for this problem are based on greedy methods and game theory. There is potential space to improve. This paper examines CTOP and identifies important strategic changes to ATM adopting this philosophy, particularly in Brazil.
Highlights
Air delay is an existing problem in most airports around the world, bringing higher cost to the airlines and discomfort to the passengers
Collaborative Trajectory Options Program (CTOP) is one of many new traffic management initiatives been developed within CATMT and is a part of the NextGen and SESAR initiatives
This name difference is basically caused by the European consortium which wants a more collaborative environment, where trajectories are agreed between all the air traffic management (ATM) stakeholders, for example air traffic control (ATC), airports, airlines, military and general aviation
Summary
Air delay is an existing problem in most airports around the world, bringing higher cost to the airlines and discomfort to the passengers. This type of inefficiency brings economic consequences for all stakeholders involved in the airline business. The total fleet is expected to double in 15 years In this context, some cities are expected to concentrate the air demand with long-haul and regional traffic, creating global hubs. The fundamental shift in ATM paradigm will be from clearance-based air traffic control (ATC) to trajectory-based ATC operations This new type of trajectory will include new constraints, for example target time of arrival (TTA), that will improve its predictability and as consequence, and facilitate air traffic controllers’ work. As [9] reminds, ATM is foremost about safety
