SESAR project IN INTR TRODU ODUCTION CTION Introduction Contents Experiment Pre-requisites: Data analysis 1. Define the way to integrate these “solutions” to the ATC Results working environment: Conclusion 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 of the impact generated on the controllers: The level of Mental Workload 3 Direction Générale de l’Aviation Civile Ministère de l'Écologie, du Développement durable, et de l’Énergie

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 5 Direction Générale de l’Aviation Civile Ministère de l'Écologie, du Développement durable, et de l’Énergie

SESAR project DAT ATA A RECORD ORDED ED AN AND AN ANAL ALYSI YSIS S Introduction CAR ARRIED IED OU OUT Contents Experiment Three kinds of parameters have been recorded to assess Data analysis mental workload felt by participants Results Performance assessment: Radio frequency data Conclusion 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 10 Direction Générale de l’Aviation Civile Ministère de l'Écologie, du Développement durable, et de l’Énergie

SESAR project FIR IRST T RESULTS ULTS AC ACHIE IEVED VED Introduction Contents Three consistent mental workload evaluations: Experiment Radio activity (number of clearances and radio occupancy) lower with Data analysis conflict aid services Results Especially for TC-SA and TC-SA and CD aid conditions Conclusion 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 The average duration of eye fixations on conflict The average maximum value of pupil diameter during The average number of eye fixations on conflict aircraft according to experimental condition eye fixations according to experimental condition aircraft according to experimental condition Eye-tracking data Number of eye fixations on conflict aircraft is higher for the reference condition The average occupancy of radio frequency per experimental The average number of clearances per experimental condition The average duration of eye fixations on conflict aircraft is lower for CD condition (seconds) ddddddddddddddd aid and TC-SA + CD aid conditions The maximum of pupil diameter during eye fixations on conflict aircraft The TC-SA and TC-SA + CD aid conditions seem to is lower for TC-SA and TC-SA + CD aid services be the most mental workload efficient The score of AIM questionnaire defined for each experimental condition The average value of ISA scale for each experimental condition 11 Direction Générale de l’Aviation Civile Ministère de l'Écologie, du Développement durable, et de l’Énergie

SESAR project CON ONCLUSION CLUSION Introduction Contents Experiment Mental workload felt by Air traffic Controllers is lower with Data analysis the use of conflict aid services: Results Especially for the TC-SA and TC-SA + CD aid services Conclusion Consistent results have been obtained with several approaches Perspective of this project: Proposing a new version of the CD aid service 12 Direction Générale de l’Aviation Civile Ministère de l'Écologie, du Développement durable, et de l’Énergie
