Safety Assessment process


Data Link HMI Definition & Prototyping Prototype of a new Human Machine Interface Related working methods for the use of the datalink services Based on the one currently in operation in Rome ACC

Efficiency Analysis Analyse the impact of data link communications on ATCOs

Workload. Definition and validation of new controller’s tasks by Real Time

simulations.

Safety Objectives Validation Specific Safety Scenarios were developed and injected in the

RTS Validation of FHA Safety Objectives compliance with the

Hazards identified in the FHA and in the ED120

FTS/RTS: step by step approach


Innovative Control Working Position solutions supporting Data Link services for testing CPDLC operations

FTS/RTS: HMI prototyping

ACL message: authorized to level … (UM19, UM20, UM21)

AB button on ALV or Modo C field label:

ALV menu to send clearances.

AB button on clearance level of right column (DL mode):

DL message will be sent.

In the label a yellow frame will close ALV field.

Pilot has receveid clearance.

Pilot will answer WILCO.

When WILCO message will be received from system, yellow frame around ALV field get off.


2 2 Real Time Simulation (Human-in-the-loop) and 1 Fast Time Simulation (SICTA and ENAV Experimental Centre)

11stst Real Time Real Time Simulation exercise aiming to define and evaluate new controller’s tasks (qualitative and quantitative approach), to feed FTS

A Fast Time Simulation exercise to evaluate the

efficiency and the potential increase of sectors capacity, based on preliminary indications from 1st RTS

22ndnd Real Time Real Time Simulation exercise to evaluate Safety and Human Factors aspects

FTS/RTS: main activities


Constant decrease of workload in each of future (CPDLC) scenario

Progressive and regular decrease of the voice communications amount

Decrease of time duration of voice communication

Increase of Sectors Capacity up to 12.8% (with 100% of traffic D/L equipped). The different results in term of capacity depend on the typology of Sectors (e.g. Feeder of Roma TMA) and the characteristic of traffic (e.g. overfly)

Slight reduction of improvement margins in case of non-nominal scenario

FTS/RTS: main results of FTS

FTS/RTS: evaluation activities


FHA Safety Objective Validation

Identification and evaluation of the effects of Hazards on the basis of ATCO behaviours and feedback

Evalutation of the effective risk related to more critical Hazards (e.g. Misdirection of message, Corruption of Flight Level message)

Supported by proof the Severity of Operational Consequences and the Safety Objectives derived from the FHA

Identification of some mitigation means to apply in design and implementation of new HMI

FTS/RTS: output of SO validation


Measurement of workload through the “Instantaneous Self Assessment”

Contract objectives

Implementation of DLIC, ACM, ACL, AMC Initial CPDLC services will be implement in Roma

ACC using VDL2 network

Implementation of data link network A new network supporting VDL2, AOA, ACARS

protocol will be developed and implemented

Implementation of D-ATIS and DCL D-ATIS and DCL will be implement in Fiumicino and

Malpensa airport using ACARS protocol

Operational Implementation


Implementation Phases

Definition, Testing, Implementation of Multimode Ground Station New VHF, VDL, ACARS Ground Station to manage ATS and AOC messages. Partnership Agreement with ARINC.

Implementation of data link network Network of initial 10 MGS to cover Roma UIR and most important airport, starting from

Fiumicino and Malpensa. MGS will be connected together and integrated in ENAV network using E-Net transport

services (ENAV program to implement ATM network connections)

Upgrade of the HMI Data link new functionality will be implement in operational HMI used in Roma ACC.

Pre-operational phase in PSA Pre-operational phase will be performed in PSA of Roma ACC (Test, Simulation and training

room) Assess operational validation of CPDLC services. Training sessions for controllers.

Operational phase CPDLC services will be implement in Upper sectors managed by Roma ACC.
