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

6 ATM Concept Baseline
This section details the baseline concept developed in response to the mission needs
identified in Section 2. The capacity-driven concept in Section 6.2 is based on the
methodology developed as part of the CNS/ATM Focused Team (CAFT) process, initially
developed to evaluate the RTCA Task Force 3 planned evolution to Free Flight. The
overall methodology is introduced in Section 2.3.6, Transition Planning and Tradeoff
Analyses. This process has been applied to the Task Force 3 recommendations, the
Eurocontrol EATCHIP plan and the IATA regional CNS/ATM Plans. The complete
methodology is described in the paper on CNS/ATM Transitions from the 1997 CAFT
meeting (Allen et al, 1997).
6.1 Concept Transition Methodology
The baseline concept is developed by considering possible capacity transitions from
current to future operations. The transition analysis is based on the airspace phases and
performance factors of the constraints analysis model. The model divides a flight into six
operating phases, going from the departure gate to the arrival gate, as illustrated in Figure
6.1. Phase 1 is airspace and flight planning, which spans the other five regions. Phase 2 is
the airport surface, phase 3 is final approach and initial departure, and so on through the
en route, which is phase 6.
