EASA HighIWC (EASA.2011.OP.28) Presented by Airbus - CNRS (LATMOS/BOM – LaMP – SAFIRE) EASA-HighIWC Final Meeting Project Overview: Context, Objectives, Deliverables EASA.2011.OP.28
EASA-HighIWC Final MeetingProject Overview: CONTEXT EASA.2011.OP.28 Commercial aircraft have been experiencing in-serviceevents (jet engine power-loss events observed in tropical convection) while flying in the vicinity of deep convective clouds since at least the early 1990s. In 2004, an industry working group was established to look at the effects of supercooled large droplets and mixed phase icing conditions on engines. The areas of aircraft that have shown sensitivity to ice particles icing threat are heated probes and engines. Ice accretion will depend on surface temperature, Liquid Water Content, Ice Water Content, air speed, etc….

EASA-HighIWC Final MeetingProject Overview: CONTEXT HAIC and EASA-HighIWCwithin international approach EASA.2011.OP.28 International HIWC fieldexperimentoriginally planned in Jan.-Mar. 2013 (then delayed by one year) out of Darwin. Use of highly instrumented G-II for in situ cloud µF of HighIWC convective clouds. G-II with 100 flight hours planned. HAIC (European L2 project) will join HIWC bringing F20 to Darwin equipped with multi-beam 95GHz Doppler cloud radar and a sophisticated state-of-the-art in situ µF package, flying at an additional flight level to G-II one. HAIC: Funding of transit + 50 flight hours of F20. EASA-HighIWC contribute to HAIC in funding the scientific and technical preparatory work of HAIC (=analysis of A340 data from 2010 and definition/preparation instrumental payload for Falcon 20).
