SEE2 948.0095/03 Presented by IATA meeting, Bangkok, 23rd April 2003 Customer Services Presented by Doug Carlile Senior Director, Environmental Systems and Cabin Interior Engineering Services SARS - Airbus aircraft systems SEE2 948.0095/03 April 2003 Page 2 © AIRBUS S.A.S. All rights reserved. Confidential and proprietary document. SARS - Airbus aircraft systems Several operator questions received on : •Products and procedures to disinfect aircraft •Handling of cabin air re-circulation filters Status communicated to all operators by Operator Information Telex (OIT) SE 999.0037/03 OIT rev. 3 update issued 15 April 2003 SEE2 948.0095/03 April 2003 Page 3 © AIRBUS S.A.S. All rights reserved. Confidential and proprietary document. SARS - Airbus aircraft systems OIT content summary : • First and foremost, advice and recommendations of local medical authorities must be sought • Aircraft Maintenance Manual references given for standard (aircraft compatible) disinfectants • If non-standard products are to be used, specific advice given on precautions for structure & furnishing materials • E-mail contacts given for specific advice from the World Health Organisation • No specific operational recommendations, it is not recommended to operate with the cabin fans off SEE2 948.0095/03 April 2003 Page 4 © AIRBUS S.A.S. All rights reserved. Confidential and proprietary document. SARS - Airbus aircraft systems Cabin Airflow Design Principles • Air enters at the top and exits downward and produces no longitudinal airflow. Air from one person passes another at floor level only. • The combination of outside air and filtered recirculated air produces a flowrate that removes cabin generated contaminants fast and raises humidity • Extracted air flows to the outflow valve and to the recirculation filters • Airbus aircraft use high efficiency recirculation filters with no bypass capability - all recirculated air is filtered. • Ventilation air used for galleys, toilets, cargo holds and avionics compartments is vented overboard. It is not recirculated. Inlet air Extracted air SEE2 948.0095/03 April 2003 Page 5 © AIRBUS S.A.S. All rights reserved. Confidential and proprietary document. SARS - Airbus aircraft systems Cabin re-circulation fan operation : • Augments cabin air relative humidity, reduces rate of drying of nose/eyes/throat • Optimises cabin temperature comfort •Maximises air exchange rate • With HEPA filters, the cabin air can have less particulate content than air from outside All Airbus production aircraft have HEPA filters SEE2 948.0095/03 April 2003 Page 6 © AIRBUS S.A.S. All rights reserved. Confidential and proprietary document. SARS - Airbus aircraft systems Cabin air filters : •Made of micro glass fibre, highly efficient filtration with low pressure drop • Reduce risk by removing dust, mold spores, bacteria and viruses • Utilize three different capture mechanisms with a collection efficiency greater than 99.97% • Virus size range 0.01 to 0.2 microns. • Corona virus size is 0.08 to 0.12 microns • Virus survival time is very low, due lack of live human cells SEE2 948.0095/03 April 2003 Page 7 © AIRBUS S.A.S.

SARS - Airbus aircraft systems Inertial impaction: Smaller particles tend to impact the filter material rather than following the tortuous path through the media. Diffusional interception: Very small particles undergo considerable motion, which increases the probability to be retained by molecular forces Direct interception: Interception of all particles which are bigger than the pore size. Filtration Principles SEE2 948.0095/03 April 2003 Page 9 © AIRBUS S.A.S. All rights reserved. Confidential and proprietary document. SARS - Airbus aircraft systems Conclusion • Operators must comply with the recommendations of local medical authorities • No specific change in aircraft operational procedures • Airbus maintains close links with the World Health Organisation and will continue to provide information updates as appropriate SEE2 948.0095/03 April 2003 Page 10 © AIRBUS S.A.S.
