post evacuation scenario has the potential to provide problems to cabin crew, flight
crew and ground rescue personnel.
The 25.803 certification requirements only takes into account the evacuation of the
aeroplane up until the time that passengers and crew have reached the bottom of the
evacuation slides.
Operational requirements take into account the need for crowd control once the
passengers have left the aeroplane.
Appendix 1 JAR-OPS 1.1010 (f) states: “Crowd control. An operator shall ensure
that training is provided on the practical aspects of crowd control in various
emergency situations, as applicable to the aeroplane type”. Additionally, IEM to
Appendix 1 to JAR-OPS 1.1005/1.1010/1.1015/1.1020 includes a reference that
cabin crew training should include ‘The marshalling of passengers away from the
aeroplane”.

During emergency evacuations, as well as during precautionary evacuations, some
exits will be opened before other exits. There is a potential for aeroplanes with “off
wing” evacuation slides and upper deck slides, for these slides to deploy on top of
passengers who have already evacuated. Although not unique to the A380-800, this
scenario is more likely in that there are two large decks and a greater number of
evacuation slides in close proximity.
Forward of the A380-800 wing there are two main deck slides and one upper deck
slide on each side of the aeroplane. Aft of the A380-800 wing there are three main
decks slides (including one off-wing slide) and two upper deck slides on each side of
the aeroplane.
The proximity of the following slides to each other might be an issue in terms of the
timing of slide deployment:
U1 and M2
U2 and M3, and M4
U3 and M4, and M5
The issue of upper deck slide interaction with passengers on the ground was raised
during the certification process, and then devolved to the JOEB for an operational
solution.
Following discussion by the JOEB, Airbus proposed to include information in all preflight
briefings that passengers should move rapidly away the bottom of the
evacuation slides, considering that while it is not possible to exclude all risks as with
other large transport category aeroplanes, the information in all pre-flight briefings to
passengers, reduces the risk identified.
The JOEB accepts that if operators implement relevant information in both
passenger briefings and safety cards, and if such information is complied with by
passengers then the risk of passengers being struck by an upper deck slide is
potentially mitigated.
As already stated, although it is not possible to entirely eradicate the risk of
passengers being struck by an upper deck slide during an emergency evacuation,
one solution is to ensure that both operators and cabin crew are made aware of the
specific safety procedures to avoid this risk.
JOEB Conclusion: Operators and National Authorities should be aware of the
issues of post-evacuation control of passengers. Operators should include in
all pre-flight passenger briefings information that in an evacuation, passengers
should move rapidly away from the bottom of the slides and away from the
aeroplane. This information should be repeated in pre-planned ground
evacuation scenarios. In an emergency evacuation, upper deck slides should
be deployed as rapidly as possible. Cabin crew should be made aware of the
above issues. Operators may wish to consider alternative cabin crew
procedures and associated training.

3- JAR-OPS 1 Subpart K – Instruments and Equipment
The EASA Certification Panel 8 criteria was for cabin emergency equipment to be
uniformly distributed throughout each deck and that each deck be treated
independently in this respect. Regulations that specify quantities or arrangements of
such provisions will be applied to each deck separately.
In addition to the emergency equipment required by certification criteria, the
requirements of JAR-OPS 1 Subpart K were reviewed by the JOEB to determine if
additional equipment was required, over and above the current requirements. Refer
to Appendix B for rationale.
The outcome is summarized in the table below and is applicable to the A380-800
at maximum passenger seating capacity:
