MFF | FLIGHT TRIALS REPORT à The MFF Project MFF main objectives are: à To provide operational requirements and procedures based on the use of new CNS/ATM technologies enabling the introduction of ASAS and Free Flight operations in Mediterranean area; à To address fight transition issues between FFAS and any other airspace (MAS in fixed routes or free routes, UMAS); à To provide users community with results to address standardisation and further maturation of relevant CNS/ATM technologies and applications both in ground systems and avionics à MFF Consortium is composed of: ENAV, AENA, DSNA, EUROCONTROL, HCAA, LFV, MATS, NLR, UK NATS. 4

MFF | FLIGHT TRIALS REPORT à MFF Applications A 1 – Free Route A 2 – Air Traffic Situation Awareness A 3 – ASAS Spacing à Remain Behind, Heading then Remain Behind à Merge Behind, Heading then Merge Behind A 4 – ASAS Separation à Lateral separation (Pass behind, Pass abeam) à Vertical separation (Pass above, Pass below) à Longitudinal separation (Remain behind, Merge behind) A 5 – Airborne Self Separation 5

MFF | FLIGHT TRIALS REPORT à MFF Applications – Delegation levels A 3 – ASAS Spacing à Execution of a separation value required by ATC. The flight crew is responsible for applying the spacing clearance issued by ATC with respect to another aircraft, while maintaining and monitoring the separation value required by ATC. A 4 – ASAS Separation à Provision and monitoring of airborne separation from one aircraft specified by ATC. The flight crew is responsible for providing aircraft separation in accordance with separation minima required for safe operations, and deciding on the means by which to provide it under possible ATC restrictions (related to the surrounding traffic or airspace). A 5 – Airborne Self Separation à Airborne self-separation of an aircraft with respect to the surrounding traffic (without ATC support). 6

MFF | FLIGHT TRIALS REPORT à The Role of FT in MFF Concept Development (WA 2) Fast Time Simulations (WA 3) • Acceptance of concepts and procedures Flight Trial (WA 5) • workload issues • Pilot situation awareness • Suitability of tools and HMI in a real environment Real Time Simulations (WA 4) 7

MFF | FLIGHT TRIALS REPORT à FT Area à Designed as a dedicated area to avoid interference with GAT/OAT activities à Designed in cooperation with ITAF, Rome ACC and several APPs à Reserved on permanent base to MFF during week ends (AIP Suppl. ) à Coordinated on tactical base with ITAF 8

MFF | FLIGHT TRIALS REPORT à Flight Trials Rules à Flights performed in a FTDA à Separation minima: à 1000 ft minimum vertical separation (also in S&M) à 8 Nm minimum (ASAS Spacing, Separation) à 5 Nm minimum separation, but 1000 ft vertical separation for FF Application à VMC day light operation à Surveillance à Radar monitoring à ADS-B/TIS-B à MFF dedicated Teams at Roma ACC and Experimental Centre 9

MFF | FLIGHT TRIALS REPORT à FT Execution Phases: 1. Missions design à FT master list à Exercise design (test cards) 2. Training à Theory (class lectures) à Practices (CDTI and cockpit simulators) 3. Missions rehearsal à aimed to examine the dynamics of missions to establish their practicability, usefulness and effectiveness à consolidation of training à evaluation of the “flight test data cards” 20

MFF | FLIGHT TRIALS REPORT à FT Execution Phases: 4. Execution à 1 real a/c vs 1 cockpit simulator à 1 real a/c vs 1 real aircraft à 1 real a/c vs 2 real a/c Total number of flight hours: 255 FIRST TIME IN EUROPE 21

MFF | FLIGHT TRIALS REPORT à FT execution Tipycal Mission: à LIRA-LIRA à Y & Z FPLs à FL 180 -190 à Duration: 3 h 30 m IFR LIRA VFR à Each mission is composed of a set of exercises aimed to evaluate a specific validation objective 22

MFF | FLIGHT TRIALS REPORT à Initial Results – ASAS Spacing à Pilots and ATCOs stated the allocation of responsibility and tasks between ATC and aircrew are acceptable. à ASAS Spacing operations increase pilots’ workload, but within acceptable limits; required attention for the CDTI/ASSAP was considered high. Further improvements on the CDTI/ASSAP (e. g. aural warnings) and its integration with avionic systems will reduce pilot workload. à Pilots and ATCOs found the phraseology long and complicated and inducing an increase of the perceived workload. The communication overhead should be reduced. à During FT the situational awareness was judged adequate by the pilots, even if they want to be informed/aware when they are target of a delegation. à The concept of tolerance should be included for the delegation parameters. 23

MFF | FLIGHT TRIALS REPORT à Initial Results – ASAS Spacing à The ASAS Spacing algorithm should take into account aircraft performance and passengers’ comfort. à Both Pilots and ATCOs should be provided with tools to a priori assess the feasibility of the delegation instructions. 24

MFF | FLIGHT TRIALS REPORT à Initial Results – ASAS Separation à Pilots stated the allocation of responsibility and tasks between ATC and aircrew are acceptable. à ASAS Separation acceptability for ATCOs should be further investigated, especially with reference to contingencies and critical situations, where ATCO has no time to prevent a loss of separation. To reduce ATCO workload, monitoring of ASAS traffic should not be requested, however it is still an open issue to be better investigated and clarified. à ASAS Separation operations increase pilots’ workload, but within acceptable limits; required attention for the CDTI/ASSAP was considered high. Further improvements on the CDTI/ASSAP (e. g. aural warnings) and its integration with avionic systems will reduce pilot workload. à During FT the situational awareness was judged adequate by pilots, even if they want to be informed/aware when they are target of a delegation. 25

MFF | FLIGHT TRIALS REPORT à Initial Results – ASAS Separation à Pilots and ATCOs found the phraseology long and complicated and inducing an increase of the perceived workload. The communication overhead should be reduced à The ASAS Spacing algorithm should take into account aircraft performance and passengers’ comfort. à ATCOs expressed the need to have ADS-B Intent information; à The concept of tolerance should be included for the delegation parameters. à Both Pilots and ATCOs should be provided with tools to a priori assess the feasibility of the delegation instructions. 26

MFF | FLIGHT TRIALS REPORT à Initial Results – Airborne Self Separation à During FT pilots positively accepted A 5 because of several positive effects (no R/T, more flight efficiency, low workload) à Pilot workload remains well within tolerable limits, even if workload should be assessed in a more realistic environment with more traffics and more complex geometries. à During FT no workload peaks were experienced à During FT the situational awareness was judged adequate. Aural warnings in case of conflict are strictly necessary. à Airborne Self Separation would benefit from having a fully integrated system coupled to the aircraft’s FMS and autopilot. à The concept of tolerance should be included for the application parameters. 27

MFF | FLIGHT TRIALS REPORT à Conclusions: the MFF WORKSHOP MFF Final Workshop “Moving closer to Free Flight in the Mediterranean” Rome – 1, 2 December 2005 The key objective of the workshop is to present the results of the innovative concepts, procedures and supporting technologies which have been assessed and simulated in five years. The focus will be on operational validation activities. . Further information may be obtained on www. medff. it or writing to workshop_secretariat@medff. it 28
