objective and approach of the study
Objective and Approach of the Study
  • Objective : identification of the main issues in order to guide future VLTA research or design
  • Approach:
    • Bibliographical research (state of the art)
      • Theoretical aspect
        • Cognitive psychology
        • Sociological field
        • Ethology
      • Past research review
  • Makerecommendations
theoretical appraisal 1 2
Theoretical Appraisal (1/2)
  • The information nature and quality are key factors in the Situation Awareness building
  • The SA is built on the basis of acquired knowledge determining the importance given to some information in the present context (prejudice, belief, etc.)
  • The SA is threatened by social factors as:
    • lack of group cohesion,
    • lack of leadership
    • lack of common experiences
  • In emergency conditions, recent acquired knowledge disappears in aid of familiar knowledge (e.g. the route to exit the plane)
theoretical appraisal 2 2
Theoretical Appraisal (2/2)
  • Emotion can forbid the access to SA during a given period of time
  • Alert phase management is fundamental to build a clear and reassuring SA
  • The group affiliation feeling has a reinsuring effect on validity of information and reinforces SA
  • The highly structured rituals setting during pre-flight and boarding phases favours
    • the spatial references
    • the time based references of the affiliation to the group,
    • allow the improvement ofthe emotional factors management
past researches review key outputs 1 2
Past researches review key outputs (1/2)
  • A lot of passengers continue to pay very few attention to safety briefings (written and oral ones)
  • Everymoment of attention capacity should be identified to use them properly. An additional safety briefing just before boarding or descent could be an alternative, especially on long haul flights
  • Passengers do not feel concerned by the safety information either because :
    • they overestimate their knowledge of safety aspect,
    • they underestimate their chances of survival,
    • they see Cabin Crews as the only safety actors possible during an evacuation (it does not worth listening to them),
    • they do not see the demonstration.

Past researches review key outputs (2/2)
  • A lot of recommendations have been already listed. They could be adapted taking into account the VLTA environment demands
  • New information means (video, interactive media…) can improve the attractiveness and the attention capture potential of the safety instructions
  • Despite safety instructions, passengers still intent to evacuate with their luggage and some personal effects.
recommendations shaped like a boarding scenario
Recommendations shaped like a boarding scenario
  • First Scene context : Cabin characteristics
    • VLTA cabin divided in several zones
    • Each zone corresponds to a safety gate
    • To each zone correspond a colour or a sign (on the seat, on the safety door, on the uniform of the CCs, on the boarding card)
    • Each zone is in charge of specific CCs
  • First Scene: Passenger Check in
    • At this first stage, passengers know their cabin area symbol (colour, sign)
    • Passengers who check in first, are assigned to area supposed to board first
    • They are provided with a bum-bag and asked to put all little “precious” objects in during all the flight (medicine, glasses, money, passport, jewels...)
recommendations shaped like a boarding scenario 2nd scene
Recommendations shaped like a boarding scenario : 2nd scene
  • 2ndScene context : Boarding room characteristics
    • Divided in the same amount of areas as the cabin
    • Drinks and light foods are proposed to promote conviviality in each area
    • A set of safety information means are proposed to passengers
    • All the information devices show the location of the areas in the whole cabin (entrance door, evacuation door of the area) and the safety briefing
    • All the safety messages are completed by technological advertisements in order to be attractive and reinsuring
  • 2nd Scene : Boarding
    • Each passenger is asked to wait to the boarding order of his area.
    • Each zone boards independently
    • The CC in charge of the zone welcomes the passenger and introduces her/himself as the responsible of the zone
    • The CC invites people to read the safety cards or to give attention to a safety message
expected effects on actors
Expected effects on « actors »
  • The Passengers Situation Awareness should contain
    • A good mental map of the aircraft with the location of her/his emergency door.
    • A precise idea of the emergency tasks involved in the evacuation (live jacket, route to reach the door, jumping,...)
    • A rational idea of the chance to survive and then motivation to be attentive to all the safety information
    • An affiliation feeling with the passengers supposed to leave the aircraft at the same door (same area).
    • The CC leadership recognition
    • The CC safety role recognition
  • An adapted collective behaviour
    • Ordered evacuation
    • CCs less inclined to move from their doors
    • Organised and spontaneous rescue and safe behaviours
