Problems to Solve

The current ATM system lacks stability and predictability which has a negative impact on decision making and efficiency.

C-ATM proposes a Mode of Operation that addresses the following deficiencies:

Stability & Predictability: Poor information distribution leading to fragmented, short-term and

uncoordinated decision making; Poor resource allocation; ‘First come first served’ leading to undesirable effects; Adverse weather affecting surface and airspace operations.

Inefficiency: Poor use of existing technology and operational capability;

Growth Potential: Human work load limitations; Airspace complexity; Airport runway, surface and taxiway complexity;

Principles

The C-ATM Concept adheres to the following principles Separation responsibility remains with the controller. Users and airports are fully integrated into the system:

Distributed air ground responsibilities enabled through Airborne Separation Assistance System package one;

Aircraft Derived Data exploited by the ground system through Data Link Airport CDM provides data to ATM processes.

Network Operations Plan - provides current information access to all, concerning the day of operation:

Built up from 18 months ahead All system participants contribute and maintain the plan; Layered planning process builds and refines the plan; Scenarios developed to manage expected and unexpected events; All actors manage according to plan – “on-time, first served”; Collaborative decision making processes implemented; a final decision

maker always declared.

Airspace Organisation & Management

A shared resource, treated as a continuum, irrespective of national boundaries.

Collaboratively developed airspace and route configurations: Dynamic sectorisation through predefined modular sector configurations; Flexible Use of Airspace with pre-defined, multi dimension and mobile

training areas; Routes are based on:

Different traffic flows predicted over a 24 hour period; Equitable application User Preferred Profiles.

Highways – defined routes with predetermined aircraft profiles; PRNAV routes and procedures enhance separation management; Continuous descent procedures to improve environment and flight

efficiency;

Layered Planning

Layered Planning is a continuous process of demand and capacity balancing.

Output is Network Operations Plan, optimal schedules and pre-defined scenarios directed to assuring a predictable ATM system.

The continuous processes are organised in three layers: More than one year before : strategic

Planning of resources and infrastructure; Optimal schedule, pre-defined scenarios

and airspace configurations; 7 days to 3 hours before : pre-tactical

7 day rolling review of plans; Airspace scenario promulgated; Airline flight planning activity; Update of Network Operations Plan.

3 hours before until end of flight : tactical Preferred user profile is filed; 4D plan and pre-tactical clearance agreed Re-balancing and traffic synchronisation

activities by Central and Local Traffic Managers

4D Plan

The 4D plan is an agreement between the network manager and AOC as to how a flight should proceed reflecting:

Capacity and demand situation for airspace and airport resources; Users preferred profile; Target times for turnaround, taxi, runway, airspace, arrival and on-blocks.

The 4D plan: Is executed by the AOC (pilot) and ATC (controller); Can be set aside for safety reasons at any time; May be amended to take account of:

Separation management and traffic synchronisation;

ATM environment changes (e.g. weather);

Application of a scenario; Specific requests by the AOC

or Military.

Co-operative Air Traffic Management

Synchronisation and Separation Management

A major goal of C-ATM is the safe and consistent delivery of aircraft according to the Network Operations Plan.

The Network Operations & 4D Plans manage traffic through: Local Traffic Management:

Local capacity and demand balancing; Local traffic synchronisation within a centre;

Sector Traffic Synchronisation: Creating sequences and flows;

Separation Management: Planning entry, exit and through sector separation; Safely separating individual flights from one another

and from known hazards.

Co-operative Air Traffic Management

Local Traffic Management

Local Traffic Management is the link between network management and separation management;

ensuring segregated organised traffic flows leading to increased sector throughput through reduced sector complexity

Carried out by the ANSP to optimise the capacity of the local network; Operates up to 40 minutes prior to traffic entering its area; Two main functions:

Local traffic balancing and local management of the network operations plan: Balance traffic flows between sectors and adjacent centres; The timely application and coordination of modular sector configurations; Coordinating with AMCs to maximise Flexible Use of Airspace.

Traffic synchronisation to organise traffic sequences on routes and in sectors: Rerouting to segregate departures, arrivals and over flying traffic; Traffic delay mechanisms (in trail, speed); Flight level allocation plans to reduce crossing traffic complexity.

Management of degraded situations and application of local scenarios, including with the network manager.

Actions that change the 4D plan are transmitted: Direct to the aircraft if impact is local; Via the appropriate sector controller for application prior to sector entry.

Air Traffic Control

Distributed air ground responsibilities facilitate an integrated flight deck and sector team.

Flight deck support through an ATC friendly FMS interface for: Managing the 4D plan and ATC clearances; ASAS surface situation awareness and sequencing and merging applications; Trajectory exchange.

Modular sectors ensure resources are allocated to traffic flows according to traffic density and workload;

Controller working positions will present filtered traffic and system support information that enhances the controllers competencies for:

Traffic assessment, separation and monitoring; Problem/conflict detection, evaluation and resolution; ASAS spacing; 4D plan management.

Medium term planning tasks remain human centred assisted by: Decision support tools for problem detection and resolution, routing,

sequencing and metering, arrival/departure/surface management, and coordination.
