Progress mostly due to : Development of avionics (large displays, situation awareness, status of A/C trajectory, GPS) Development of Collision avoidance (ground GCAS, air TCAS) TOMORROW EXPECTATIONS Users expect a safety improvement by a factor of "ten", meaning no more than one accident in Europe in commercial transportation every three to five years. Achievement of this ambitious objective will request efforts in all domains with : A new approach of aircraft systems (better monitoring, fail passive & fail operative generalization) A large effort in the domain of continuous airworthiness A redefinition of the crew role (pilot misjudgment is becoming the prime source of accident) Nevertheless for years and years the pilot will remain the "ultimate computer" GCAS : Ground Collision Avoidance System TCAS : Traffic Collision Avoidance System

Page 4 SL2006-51 ASAS TN2 Glasgow 060912.ppt Crew Role CREW WORKLOAD In terminal area, under critical circumstances crew workload can be high (too high) Communications in use today represent a large part of the pilot workload Solution is to use datalink and to limit voice coms to a minimum (specific procedures) Aircraft configuration management is an other one Solution is to develop automatic management of Slats, Flaps, A/B, Landing gear and to use FBW to maintain the aircraft in its flight envelope and to counter engine failure CREW COORDINATION Generally airliners are proud of their "crew procedures" Unfortunately these procedures are sources of misunderstandings and errors Solution : One pilot in charge of the flight behavior, the other one in charge of the monitoring PILOT FORMATION It's a new and difficult challenge. Aviation will need more & more pilots. Pilot selection criteria are changing "less skill, more expertise" FBW : Fly by Wire

Page 6 SL2006-51 ASAS TN2 Glasgow 060912.ppt Cockpit Crew Organization COCKPIT "1" QCM (Qualified Crew Member) (CS/FAR 23/25-1523) Purpose of this cockpit To allow FAR 25 aircraft (Cargo) operations with only one crewmember To allow FAR 23/25 Business Jet operations with only one crewmember Aircraft configuration The aircraft is configured as a UAV (flight might be made in complete automatic mode) The crewmember monitors the flight operation and intervenes in case of malfunction The crew can flight the aircraft through the FBW but only using upper modes Less crew qualification No direct flight operation in "roll" mode (to avoid spatial disorientation effects) Initial application VLJ aircraft ( Eclipse is envisaging on its VLJ "an automatic aircraft recovery system in the event of pilot incapacitation). AC 25-1523-1 Minimum Flight Crew 4.c.(4)(vi)(B) Although Part 25 does not specifically disallow certification of single piloted transport category airplanes, the FAA has been reluctant to approve this operation when all aspects of the intended use of the airplane and the consequence of pilot incapacitation are considered, as well as the historical accident record noted in paragraph (A) above.

Page 10 SL2006-51 ASAS TN2 Glasgow 060912.ppt ASAS ASAS (Airborne Separation Assistance System) Traffic increase will increase the number of actions to maintain proper A/C separation There is a need to put the "pilot in the loop" and so to develop ASAS methods ASAS means also additional workload for the crew ASAS CONCERNS & PROPOSALS Symbology must be "crystal clear" (Controller in absolute mode, crew in relative motion) Actions must always follow the same rules and must be coordinated (ATC & crews) A PRELIMINARY PROPOSAL FOR "AIRCRAFT CROSSING" The procedure will have to be initiated by the ATC controller (normal case) Only one aircraft will do the maneuver, the aircraft which is passing "aft" (wake vortex) The maneuver will consist in a turn (track change) in the direction of the intruder To minimize the trajectory change, the maneuver will be initiated when the track change will correspond to a predetermined selected value (20°) The procedure can be made in automatic mode (pilot arming the sequence)

Page 12 SL2006-51 ASAS TN2 Glasgow 060912.ppt Concerns FIRST CONCERN It is important to keep independent aircraft separation (ADS-B) from collision avoidance In case of TCAS alert (TA), ASAS symbology must be removed and replaced by TCAS one There is a risk that a pilot involved in an ASAS action will not thrust the TCAS order Solution might be to implement an automatic TCAS SECOND CONCERN A communication party (A/C crews & controller) must be implemented (Data link & voice) Party organized by ATC controller Coordination by messages (A/C doing the maneuver, start and end of maneuver) THIRD CONCERN Accuracy of A/C positions (accuracy and time delay) Integrity of aircraft positions (GPS), (possibility to correlate aircraft distance (mode S)) Use of a common means of communication (TCAS mode S, ADS-B 1090 ES) POSSIBILITY Possibility to reduce separation distance without wake vortex effect, by increasing the "aft aircraft" altitude to flight slightly above the intruder (~100 ft baro-alt & GPS alt) In any case "separation distance" must be sufficient to not trigger TCAS TA
