DOCUMENT OBJECTIVES AND SCOPE 

As the prior section indicated, Doc 9854 and derived documents call for increased levels of collaboration across the spectrum of decision-making. While these documents indicate a need for and a description of the applicable areas of collaboration, the guidance on implementing CDM is not complete; this manual provides that additional guidance.

It is recognized that CDM is applicable to long-term planning activities such as infrastructure investments and procedural changes. For those types of activities, the performance-based approach, as described in Doc 9883, provides guidance on the methods for attaining collaborative, performance-focused solutions. Furthermore, given the long time horizons available for collaboration, rules, methods and roles of individual collaborating participants can be customized to the situation. Some types of decisions are out of the scope of this manual and will be covered by Doc 9883, Part I — Global Performance and Part II — Performance-based Transition Guidelines, First Edition, 2009.

For other types of CDM requiring additional guidance beyond the performance-based approach (e.g. agreement on day-of-operations configurations, flight-specific trajectory changes as required for queue or traffic flow management), this manual provides guidance material in the following areas:

a) CDM description in addition to overarching collaboration principles and processes, which include:

1) a description of the ATM areas suitable for collaboration;

2) a classification and description of the types of collaboration, and conditions under which they apply;

3) a description of complementary decision-making, and conditions under which it may apply; and

4) issues to be addressed when implementing collaborative processes, including the use of rules managing behaviour;

b) the role of information exchange — information-sharing is central to collaborative processes; important considerations in this area are described below:

1) data standards — why standards at a syntactic and semantic level are necessary;

2) information quality — types of approaches for mitigating impacts, where applicable; and

3) role of the collaborative environment — how the information for a collaborative environment supports collaboration;

c) articulating a CDM process — identifying what is necessary to describe a CDM process given an objective for collaboration, including:

1) participants — who is participating in the collaboration;

2) roles and responsibilities — what functions do the participants perform and how do they interact;

3) information requirements — description of requirements and standards imposed on information exchanged as part of the above interactions;

4) making the decision — how is a decision made; and

5) rules — what are some rules constraining the behaviour;

d) examples of present-day CDM processes, which include:

1) airport and surface CDM;

2) network operations planning;

3) coordination of airspace use;

4) CDM under adverse weather;

5) special traffic management programmes and security; and

6) use of collaborative working groups and tools.
