Challenges

Commercial aircraft has been experiencing in-service events while flying in the vicinity of deep convective clouds since at least the early 1990s. Heated probes and engines are the areas of aircraft most prone to mixed phase and glaciated icing threat. In anticipation of regulation changes regarding mixed phase and glaciated icing conditions, the HAIC project will provide the necessary Acceptable Means of Compliance (numerical and test capabilities) and appropriate ice particle detection and awareness technologies to the European aeronautical industry for use on-board commercial aircraft in order to enhance safety when an aircraft is flying in such weather conditions.

HAIC will achieve high Technology Readiness Level (TRL6) for technologies (radar, detector) and capabilities (numerical models and tools, test facilities) developed as part of the project. HAIC will also develop international cooperation and collaboration thanks to the involvement of key international organisations and companies as partners of the project or through the HAIC Advisory Board.

Finally, HAIC will complement the work performed by existing international projects and working groups, notably EASA-HighIWC (European Aviation Safety Agency - High Ice Water Content), HIWC (High Ice Water Content), EIWG (Engine Icing Working group) and ICC (Ice Crystal Consortium), and pave the way towards the ACARE (Advisory Council for Aeronautics Research in Europe) 2020 and Flight Path 2050 safety objectives.
