Objectives

The main objectives of the HAIC project are to allow the European aeronautical industry to face challenges related to the evolution of regulation regarding mixed phase and glaciated icing conditions by characterising high ice water content environments and developing the Acceptable Means of Compliance (test facilities and numerical tools), to improve aircraft operation in such weather conditions by developing appropriate detection and awareness technologies to be fitted on aircraft and being able to alert the flight crew and thus to continuously enhance international flight safety.

In particular, within the HAIC project the characterization, optimization, enhancement and selection of the most sophisticated cloud microphysics probes will be performed in order to measure mixed phase and glaciated icing conditions during flight tests and to calibrate icing wind tunnels. Furthermore, within the HAIC project the measurement and characterization of the microphysical properties of core or near-core regions of deep convective clouds, including cloud liquid and ice water contents and particle size and shape distributions, is expected to be performed.

Moreover, the HAIC project is expected to develop the Acceptable Means of Compliance through the understanding and modeling of the specific physical phenomena, the development of numerical tools and the upgrade of the European icing wind tunnels capabilities in order to simulate the impact of mixed phase and glaciated icing conditions on aircraft components and to allow the European Aeronautical industry to perform equipment qualification.

Another important objective of the HAIC project is related to the improvement of the aircraft operation and the enhancement of international flight safety when flying in mixed phase and glaciated icing conditions. In order to do so, appropriate detection and awareness technologies to be fitted on aircraft and able to alert the flight crew or enable the adaptation of the flight path well in advance so as to avoid flying in such weather conditions.

Additionally, within the HAIC project the assessment of the proposed mixed phase and glaciated icing environment and the provision of recommendations to the regulatory bodies (European Aviation Safety Agency (EASA) and Federal Aviation Administration (FAA)) is expected to be performed. Finally, the HAIC project promotes international cooperation and collaboration thanks to the involvement of key international organizations and companies as partners of the project and through the HAIC Advisory Board.
