SL2. PBN feasibility assessment

ESSP relies on its own PBN feasibility methodology to evaluate the most suitable PBN solutions, as a function of the customer needs, requirements and its operational reality.

This service is intended for decision makers of ANSPs, airport operators, CAAs and NSAs. ESSP delivers extensive and detailed reports which can be used as guidance and business arguments to move forward into the actual implementation and all benefits that will come from it.

ESSP performs the following activities divided in different subservices for the customer:

• Traffic and fleet CNS assessment
• Conceptual airspace design
• Airport operating minima and MET assessment
• Instrument approach procedure benchmarking assessment
• CBA for aircraft and airport operators

SL2.1 Traffic and fleet CNS assessment

WHAT To ascertain the rate of aircraft operators to reach by the airport through the implementation of new instrument flight procedures.

HOW The evaluations comprise the NAV-COM-SUR on-board equipment, as well as the AOC readiness.

The following on-board capabilities are taken into account:

• NAV: conventional and PBN
• COM: conventional and data link – based
• SUR: conventional and ADS-B

SL2.2 Conceptual airspace design

WHAT To evaluate the implementation feasibility in terms of:

• Airspace compatibility
• Obstacle terrain clearance
• Achievable minima
• Annex 14 OLS penetrations

HOW To develop preliminary airspace and procedure design. It includes a proposal accomplishing airspace constraints and other operational user requirements but does not include a complete obstacle assessment.

SL2.3 Airport operating minima and MET assessment

WHAT To ascertain that the rate of DDC (delays-diversions-cancellations) could have been avoided thanks to lower operating minima.

HOW The evaluation considers the airport’s meteorological history data exploitation. Airport operation disruptions are evaluated with regard to MET conditions (VIS/RVR, cloud ceiling).

SL2.4 Instrument approach procedure benchmarking assessment

WHAT To select the instrument approach flight procedures of a network of airports that need to be upgraded.

HOW Undertaking benchmarking analysis for selecting the best candidate scenarios (airport infrastructure+navaids+AOCs).
