Final objective:

Development of an operational concept in the 4DTRAD environment Environment including CPDLC for 4D clearances To resume: Introduction of a partial automation of the ATC task

Resolution of a part of conflicts by an automated system

Concept of SESAR W.P.4.7.2:

Including two complementary services in ATC working situation:

The TC-SA service: De-conflicting service The CD aid service: Conflict identification

Make easier the detection and resolution of conflicts for controllers

Pre-requisites:

• 1. Define the way to integrate these “solutions” to the ATC

working environment:

Integrate conflict aid services to the working situation

Define the HMI (Human Machine Interface) that could be used

• 2. Determine which parameters make possible the evaluation
• f the impact generated on the controllers:

The level of Mental Workload

Working position chosen:

All electronic => The controllers has to give information to the interface about his/her actions Built by the R&D service of the French civil aviation Composed of 2 main parts: An upper part: The radar screen A lower part: A Wacom pen display

Including conflict aid services in the working position:

Dedicated study Solutions chosen:

• 1. TC-SA: Conflicts automatically resolved => A green clock on the label of aircraft

constrained by speed adjustment

• 2. CD aid: Residual conflicts detected appear in a timetable

Three kinds of parameters have been recorded to assess mental workload felt by participants

Performance assessment: Radio frequency data

Number of clearances and radio occupancy Subjective assessment: ISA assessment scale and AIM questionnaire Evaluation of mental workload felt (from 1 to 4), each 5 minutes periods Questionnaire to assess the impact of automation on mental workload Objective assessment: Eye-tracker data Number and duration of eye fixations Pupil diameter data

Three consistent mental workload evaluations:

Radio activity (number of clearances and radio occupancy) lower with conflict aid services Especially for TC-SA and TC-SA and CD aid conditions Subjective assessment shows a higher level of mental workload felt for reference condition Lower levels are observed for TC-SA and TC-SA and CD aid conditions Eye-tracking data Number of eye fixations on conflict aircraft is higher for the reference condition The average duration of eye fixations on conflict aircraft is lower for CD aid and TC-SA + CD aid conditions The maximum of pupil diameter during eye fixations on conflict aircraft is lower for TC-SA and TC-SA + CD aid services

The TC-SA and TC-SA + CD aid conditions seem to be the most mental workload efficient

The average number of clearances per experimental condition The average occupancy of radio frequency per experimental condition (seconds)

Mental workload felt by Air traffic Controllers is lower with the use of conflict aid services:

Especially for the TC-SA and TC-SA + CD aid services

Consistent results have been obtained with several approaches

Perspective of this project:

Proposing a new version of the CD aid service
