Air Traffic Management Concept Baseline Definition - The Boeing ...

• Definition of normal, non-normal and rare-normal conditions for each
operating phase in the ATM system, and accounting for these in the entire
process to ensure that systems will be certifiable.
2. The relationship between capacity and efficiency must be developed, including the
following primary components:
• Degree of structure needed to ensure throughput as contrasted with
routing flexibility to achieve efficient flight.
• Internal schedule flexibility for larger operators, and how collaborative
decision making can be incorporated in flow planning.
• Flow planning and separation assurance for improved routing flexibility.
Planning roles in the system must be coordinated and clearly defined.
3. Transitions from en route to high density terminal areas must be addressed. One
of the possible methods is to base a plan on required time of arrival at particular
points around the terminal areas. The need to perform conflict prediction and
resolution through possibly intermediate sectors is an issue.
4. Trajectory prediction accuracy and use of intent information for traffic planning
and separation assurance must be addressed, in the context of the collision risk
model discussed in item 1.
5. Flow planning in extended terminal areas and high density regions such as the
northeast corridor is a challenging topic and of considerable importance.
6. Surface automation and the overall coordination with terminal area airborne
operations must be examined.
7. The problem of wake vortex in a variety of situations (including approach,
departure, parallel approaches and airborne) is one of the largest challenges on the
road to increased capacity.
8.3.4 Human Factors Performance
The output from the following items could be in the form of contributions to both a
database and knowledge base. It may be possible to formulate either models or analysis
and development tools in specific instances.
1. Decision Support Systems:
The main issues identified in Section 4.3.1 were how controllers would become
dependent on decision support systems, how this dependency might affect
situational awareness, and what type of intervention skills may be necessary for
any rare-normal or abnormal events. Research should be focused at identifying the
relationship between dependency and situational awareness with specific emphasis
on determining the ability of the controller to:
• Identify when intervention is necessary
• Maintain the necessary skills to intervene.
