INTERIM REPORT – DATA SUMMARY AND ANALYSIS
EASA.2009.OP.21
1.3 Questionnaire respondents
As of 15 th October 2010, completed questionnaires have been received, as follows:
− 37 questionnaires from the Aerodromes
− 69 questionnaires from the Service Providers
− 30 questionnaires from the Air Operators (Questionnaire 1 - Regulations and
Operations)
− 25 questionnaires from the Air Operators (Questionnaire 2 - Maintenance, including
Quality Assurance)
− 13 questionnaires from the National Aviation Authorities
Thus, the overall participation of the stakeholders is considered to be most satisfactory.
The different response ratios of the stakeholders may, in themselves, be interpreted as a
potential finding of the study.
− The high level of participation of the service providers can be explained by the fact that
they are the most involved in the field of de-icing / anti-icing, and will be potentially the
most affected stakeholder group by the impact of this present study. The identification
of a responsible person for this study and the provision of detailed quantitative figures
was straightforward, possibly because service providers are used to being frequently
audited by the aircraft operator.
− The medium level of participation of the aerodromes (37 answers for over 150
aerodromes directly contacted) is related to their current level of involvement in deicing
/ anti-icing services. Most aerodromes do not provide directly for de-icing / antiicing,
and therefore do not feel responsible for third-party providers. Such aerodromes,
within the study, simply forwarded the relevant questionnaires to their service
providers (this further also explains the high participation of the service providers).
− The medium, and partially incomplete, involvement of the NAAs in the study is
probably due to the difficulties of the authority to identify a central focal point
responsible for the field of de-icing / anti-icing. In most cases, no such dedicated
persons exist within the NAAs.
− The medium level of participation of the aircraft operators is due to similar reasons as
mentioned above for the NAAs. De-icing / anti-icing related matters are dealt with by
several distinct departments (air operations, quality assurance, maintenance etc.), and
the identification of a focal point was difficult.
