mass, number and size. For these reasons the ICAO Committee on Aviation Environmental Protection
(CAEP) is currently working on developing an aircraft engine particulate matter emissions certification
methodology. Towards that end CAEP is coordinating with the SAE E-31 committee which is responsible for establishing standard methods and recommended practices for sampling and measurement
of aircraft exhaust emissions. E-31 has previously
developed the Aerospace Recommended Practice (ARP) on smoke which was adopted by ICAO in the first edition of Annex 16 Volume II. This year the Committee has also finalised and approved the Aerospace Information Report (AIR) on the measurement of non-volatile particle emissions.
EASA is already working within CAEP and last year the Agency became a member of the SAE E-31 committee in order to closely participate in the development
of an ARP on non-volatile particle emissions.
When published, this ARP is expected to be used by ICAO and regulatory agencies to underpin a certification requirement on aircraft engine particle
emissions.
Research and development_ In order to contribute
towards the CAEP and E-31 work, EASA funded a study on airplane particle emissions (APE) in 2008. This has been followed up by a further research
study, SAMPLE, in 2009 to consider some of the outstanding questions regarding sampling and measurement of aircraft engine PM emissions. This study has been successful in bringing together key expertise on this issue from all over Europe, and coordinating with US FAA/EPA research projects on this same subject, with the aim of closing knowledge
gaps and progressing quickly towards a robust
PM certification requirement.
The next CAEP work programme will start in 2010 and end in 2013. One of the work items is likely to be the development of an aircraft engine based metric and methodology for application as a non-volatile PM emissions certification requirement. Significant effort is needed to achieve this task, and EASA will further contribute to this by launching a follow-on research study in 2010 known as SAMPLE II. It will build on the results and conclusions from the initial study by focusing on the sampling system and on aircraft engine tests. The Agency will also host the next SAE E-31 particulate matter subcommittee
meeting in November this year.

On 24 November, the Agency will be hosting a pilot
training conference close to its headquarters in Cologne, Germany. The symposium addresses what is emerging to be a global consensus that training needs to move up on the safety agenda. Issues
include future training needs for increasingly automated aircraft and the challenges of working in congested airspace. The purpose of the conference
is primarily to exchange views and identify key elements of best practice. The Agency’s initiative
brings together experts and speakers from Europe
and worldwide. John M. Allen, Director, Flight Standards Service FAA, will kick-off the debate along with EASA Executive Director Patrick Goudou and set the scene from the US and European perspectives,
followed by contributions from industry representatives.
The agenda is available on the events page of our website and we will keep readers posted of the outcome of the conference via the EASA News electronic
newsletter.
From 2 – 3 December, EASA will for the third year running provide the rotorcraft community with a forum to discuss initiatives or issues in the field of rotorcraft safety. Topics include rotorcraft design, continuing airworthiness, regulatory approval and operational matters. Speakers include Gunter Carloff,
Executive Director of the New European Helicopter
Association and senior representatives from the world’s leading helicopter manufacturers.

The activities of the product safety department in the past months are occurring in a general context of revision of the rulemaking programme department
in order to provide support to the Air Traffic Management and aerodrome department. Two significant events deserve to be highlighted: the publication of the amendment 6 of CS-25 which introduces new specifications for thermal/acoustic insulation material, for flight in icing conditions and for fuel tank flammability reduction and the positive
