DIFFERENT DESIGN OPTIONS BASED
ON POINT MERGE SYSTEM FOR
METROPLEX OPERATIONS
Özlem ŞAHİN MERİÇ, PhD.
AIM
The parallel and serial combination of PMS STAR model
has been designed in the radar simulator for adjacent
airports in the same terminal area which defined as
metroplex.
POINT MERGE SYSTEM (PMS)
PMS is an innovative method which merging arrival
traffic flows on a single point, not on an axis, and it
enables sequencing arrival traffic with Continuous
Descent Approaches (CDAs) [1]. The elements of
PMS are sequencing legs, range rings and a merge
point [Fig.1]. And also typical design options of PMS
are shown in Figure 2.

METROPLEX AIRPORTS
“Metroplex” is a term which could be defined as a
system of two or more airports whose arrival and
departure operations are highly interdependent [3].
Istanbul Ataturk International Airport (LTBA) and
Sabiha Gokcen International Airport (LTFJ) are in the
same terminal control area and in close physical
proximity (20nms). They could be considered as
metroplex airports. At these airports RNAV (GNSS)
STARs have been implemented [Fig.3 and Fig.4].

PMS STAR MODEL PROPOSAL
A PMS model with serial and parallel combinations has
been implemented to LTBA (Rwy 05) and LTFJ (Rwy 06)
metroplex airports. It is presented in Figure 5.
CONCLUSIONS
This PMS model proposal has the following expected
benefits at metroplex airports:
• Improve flight efficiency and predictability
• Improve descent profiles (CDA) and minimize the
environmental impact
• Provide more orderly traffic flows with predefined
trajectories
• Standardized controller working methods and also
improve controller situation awareness
• Reduction in controller’s workload and frequency
occupancy
• Maintain or possibly increase airspace capacity.
