Traffic Synchronization Services

The services that FerWay can provide are illustrated by means of practical ATM System questions and paths for solution that FerWay services will employ. Most importantly, the  questions illustrate the types of challenges in which FerWay can support your organization. Feel free to contact FerWay for your specific ATM Developments and their innovations.

 

In this section, some examples of questions that an ANSP may encounter when progressing towards Trajectory oriented ways of managing Air Traffic.

 

To the left, an example of Trajectory Management at work in real life. This is a perfect example of a concrete step towards true Traffic Synchronization. The blue profiles shows lateral trajectories in the terminal area with a Trajectory Management solution, the red trajectories represent a baseline set without such a solution.

Question: Progressing towards Trajectory Oriented Operations.

 

We have developed requirements for our Arrival Operation. We also established that in order to achieve those goals, we need to enhance the operation by Trajectory Oriented solutions. What kind of solutions could we consider in the near term and how do we implement them? 

 

Solution:

  • Several options for operational Trajectory Management elements will be reviewed and assessed:
    • Airborne based solutions
    • Ground based solutions
    • Hybrid forms
  • Selection from these options depends on many factors that will be analyzed:
    • ANSP preferences
    • Fleet mix
    • Airspace structure (complexity, external centers)
    • Air-Ground integration
    • Performance of ground based infrastructure (ATM Technical Systems).

Once the option or options have been selected, the requirements for the ATM System are defined in view of the current ATM System configuration. For example: if a ground based solution is chosen, the requirements for the TP accuracy, AMAN performance and procedures are defined. The requirements for support tools to assist in generating Trajectory Management Solutions are also defined.

Question: Trajectory Management to integrate ATC units, sectors and centers.

 

We want to improve integration of our ATC operations across different units and sectors. How can we use Trajectory Management Solutions for that? 

 

Solution:

  • The situation with respect to the units and sectors of interest are analyzed:
    • inter-unit and centre system support functions, data exchange, etc.
    • inter-unit and centre procedures
    • ATC and airline operating practices.
  • From the analysis, solutions are designed to create small steps towards an integral trajectory approach, resulting in increased predictability for ATC and pilots. For example: In a non-AMAN supported operation, too much traffic may be delivered to the terminal area. If the introduction of an AMAN operation is too big a step, other support tools may be devised and developed to support awareness across units. This tooling will use integral trajectory information to foster this awareness. Requirements will be defined to achieve this integral trajectory information and may be as detailed as software specifications for an existing or new support tool.

Question: Trajectory Management and Air-Ground Integration.

 

We are exploring possibilities for better Air - Ground trajectory information integration. Which possibilities would fit our ATM System best and which modifications could we start with to make actual progress in this field? 

 

Solution:

  • The following components will be analyzed:
    • The current technical capabilities of the ATM Systems, including availability and use of air-ground datalink.
    • The extent to which Trajectory related information is managed within the ATM System as well associated procedures.
  • From the analysis, several design solution will be evaluated taking into account factors like: complexity, cost, target Operational Concept, etc.
  • For the design solution chosen, detailed requirements will be defined to add required system functionalities and/or operational procedures.
  • Additionally, training of operational personnel or interactive sessions with airline pilot representatives can be held to facilitate smooth introduction.

Question: Trajectory Management to achieve Continuous Descent Operations (CDO or CDA).

 

Our target Operational Concept includes development towards CDO for our main airports. Which changes are needed to our technical systems and procedures? Do we need to redesign airspace, arrival & departure routings and profiles?

 

Solution:

  • An extensive analysis is conducted of the current Arrivals Operation including: systems, procedures, airspace, profiles and operating practices. 
  • Several configurations of systems and procedure modifications are evaluated and weighed against all the relevant criteria. 
  • The balanced solution chosen will then be further detailed such that these changes can be developed and implemented by the organization possibly with further assistance in specific areas like operational validation.
