Comparison of FAA 2005 and Users’ 2005 Operational <strong>Concept</strong>s<br />

Separation<br />

assurance<br />

<strong>Traffic</strong> Flow<br />

<strong>Management</strong><br />

Gaps<br />

Responsibility still with Service Provider.<br />

Changes to separation assurance function a result of increased decision<br />

support (conflict detection and resolution)..<br />

Availability of flight data for all flights. Improvements in separating<br />

controlled and uncontrolled flights and in VFR flight following service.<br />

Separation from SUA - activity info. availability allows more efficient<br />

planning of trajectories<br />

New role - Coordination of the dynamic changes to airspace structure.<br />

Better real-time information (airborne times) gives improved<br />

capabilities for strategic management.<br />

NAS info. available to all Users .<br />

Problem solving to change structure/flows a collaborative process<br />

involving Users.<br />

Use Conflict Detection tools of en-route control but with longer time<br />

horizon.<br />

Doesn’t cover benefits.<br />

Doesn’t talk of where capacity will come from. Doesn’t refer to<br />

separation assurance being transferred to pilot.<br />

Responsibility still with Service Provider.<br />

Reduced horizontal separation standards - in form of time-based separation. -<br />

provides more capacity.<br />

CDTI for more GA a/c enhances safety.<br />

Use of ground system enhanced conflict probe and alerting.<br />

Doesn’t cover much of the Ground System.<br />

Doesn’t refer to pilot taking over separation assurance role - even in specific<br />

circumstances<br />

Differences Covers <strong>Traffic</strong> Flow <strong>Management</strong> Doesn’t refer to <strong>Traffic</strong> Flow <strong>Management</strong>.<br />

Covers international aspects of flight plan transfer.<br />

Refers to VFR access to busy terminal airspace.<br />

Key Aspects<br />

Carrier preferences on the sequencing of their arrival aircraft<br />

Flexible airspace structure. Route structure only for high density<br />

periods. Facility boundaries are adjusted to accommodate dynamic<br />

changes in airspace structure.<br />

Automated inter/intra facility coordination and communication<br />

functions.<br />

Doesn’t refer to Free Flight. Doesn’t talk of separation assurance being vested<br />

with pilot.<br />

Refers to Ground Based Conflict Probe thus assumes separation assurance<br />

remains with Service provider.<br />

Covers international aspects of flight plan transfer<br />
