Progress and prospect of meteorological service for aircraft flight test in China
With the advancement of China's aviation industry,particularly through the continuous breakthroughs in the development of domestic civilian aircraft models,meteorological services and technical research for aircraft flight tests have garnered increasing attention from various sectors.Due to the unique,high-risk,and complex na-ture of flight test scenarios,new demands have been placed on meteorological services.Compared to typical civil aviation meteorological service settings,flight tests require more stringent weather conditions,have different thresholds for high impact weather events,and unlike commercial aviation,which avoids hazardous weather,flight tests need to seek out specific weather conditions.Consequently,there is a higher demand for precise forecasts of high impact weather,particularly with a lower tolerance for false alarms.Flight test meteorological services en-compass seamless forecasting and prediction,climate condition analysis,observational plan design for flight test campaign,and interpretation of meteorological standards for airworthiness,etc.This article analyzes the current state of meteorological services for flight tests in China,focusing on mile-stone events during type certification flight tests and key subjects such as aircraft icing.It is found that China pos-sesses relatively abundant flight test climatic resources,which is sufficient to guarantee the relevant aircraft models to complete all the special weather flight tests in domestic environment for type certification.Utilizing long-term,multi-source meteorological observation data and effective diagnostic algorithms can enhance flight test scheduling more rational and more scientific,thereby improving flight test efficiency.More accurate aircraft icing potential forecasting methods,combined with analyses of aircraft icing meteorological characteristics based on multi-source observations,have enabled efficient organization and accomplishment of domestic aircraft type icing flight tests,also providing preliminary insights into the microphysical characteristics of super-cooled clouds in China where aircraft icing occurs.However,the phenomenon of"over-prediction"in aircraft turbulence index forecasting algo-rithms still presents challenges in accurately capturing turbulence during flight tests.Considering future needs with further advancements in aircraft manufacturing and flight test in China,in-depth research in meteorological support technologies for flight test,like aircraft icing and turbulence,remains necessary,such as studying different icing environments and their transformation mechanisms and integrating artificial intelligence with physical meth-ods to improve turbulence forecasting accuracy.
