Research program background (IISU)
Direction Générale Aviation Civile

• Tasks to be improved in the evacuation process
• Evacuation decision.
• Understanding of the situation (passenger, cabin
  crew, cockpit status).
• Preparation of evacuation.
• Order evacuation.
• Decide on the exits to be used.
• Guidance of the passenger.

Research program background (IISU)
Direction Générale Aviation Civile

• Propositions of solutions
• CAMERA provides real time image of the aircraft
  external conditions to flight crew.
• CHECK (CHeck Exit and Communicate Knowledge)
  provides cabin crew with the contextual status of
  the usability of all aircraft exits.
• SOUND A sound is emitted by loudspeaker. The
  directional sound emitted attracts passengers to
  usable exits.
• HEADSET enables several users to communicate
  with one another, very helpful in darkness and
  smoke conditions.
• SPYHOLE provides cabin crew with an increased
  range of visibility concerning aircraft external
  conditions and enable him to determine, from
  within the cabin, the presence of obstacle or
  fire in the vicinity of his emergency exit.

IISU2 Introduction
Direction Générale Aviation Civile

• This study follows the IISU project.
• Aim of these experiments to assess the
  possible improvement of CHECK and SOUND
  technologies in the evacuation process.
• 8 trials were carried out at Cranfield
  University.

IISU2 Results.SOUND
Direction Générale Aviation Civile

• H1.1 SOUND will not disturb CC when shouting
  their instructions to passengers.
• Cabin crew point of view
• SOUND is useful for CC at a blocked door, if it
  is switched off at his door, to identify usable
  exists.
• SOUND induces an additional workload.
• SOUND is too loud when door opened.
• CC have to stop shouting to listen.
• Passenger point of view
• SOUND is an alternative mean to find their way
  out even if it could be a competing resource
  compared to CC voices.

IISU2 Results.SOUND
Direction Générale Aviation Civile

• H1.2 SOUND will have a reassuring effect on
  passengers who feel less lost in the cabin.
• SOUND system seems to provide a reassuring
  effect, even if some of them had difficulties to
  understand and use it.

IISU2 Results.SOUND
Direction Générale Aviation Civile

• Synthesis
• The major issue is the redundancy between SOUND
  and Cabin Crew, using the same sense (hearing).
• SOUND did prevent the CC from communicating with
  each other in the cabin.

IISU2 Results.CHECK
Direction Générale Aviation Civile

• H 2.1 CC are going to better structure the
  evacuation process by enriching their situational
  awareness.
• CHECK enables to enrich situation awareness.
• It is possible to anticipate the expected
  passenger flow.
• CHECK induced an additional workload.
• H 2.2 With CHECK, CC will increase self
  confidence, with will allow them to be more
  assertive when guiding passengers.
• CHECK is a reliable/supporting/reassuring tool.

IISU2 Results.SOUND and CHECK
Direction Générale Aviation Civile

• Cabin Crew point of view
• CHECK is a primary mean and SOUND is a secondary
  one.
• Passenger point of view
• The redundancy between SOUND and Cabin Crew,
  using the same sense, obliged passengers to
  choose one mean.
• The lack of an adapted phraseology for Cabin
  Crew is an other issue.

IISU2 Proposals
Direction Générale Aviation Civile

• Further studies should be done in order to
  assess
• The real impact of SOUND on the evacuation
  duration.
• The impact of SOUND on the CCs ability to work
  as a team.
• The real impact of CHECK on the evacuation
  duration.
• The impact of a CHECK phraseology on passengers.
• The impact of a weaker induced workload.
