“…The National Transportation Safety Board (NTSB) of the United States attributed the accident to icing meteorology caused by supercooled large droplets(SLD) with a diameter larger than 50μm 4 . After the Roselawn air accident, the icing meteorology, icing mechanisms, icing detection technology, anti-icing/de-icing technology, and airworthiness certification for SLD have become hot research topics internationally [5][6][7][8] . Subsequently, FAA issued Amendment 140 in 2014 9 , and EASA issued Amendment 16 in 2015 10 .…”

Ice detection of supercooled large droplets(SLD) is a key technology for ensuring aircraft flight safety. With reference to the advisory circular and combination of the flight scenarios, this paper studies the visual cue technology of SLD using numerical simulation method based on the Common Research Model. Unstructured grids are generated for the entire model, and FENSAP-ICE software is used to obtain the droplet impingement characteristics. Sensitivity analysis of the icing and flight parameters is carried out. The droplet impingement characteristics after encountering normal droplets and SLD conditions are analyzed. The reference component and it's specific visual location for visual cue are determined.

“…Aircraft deicing can be divided into three types in accordance with deicing mechanism: freezing inhibitors, heat melting ice, and surface deformation. 3 It has already emerged a variety of new technologies, and some technology has been successfully tested and applied in aircraft ground deicing. Typical of these technologies include infrared deicing technology, microwave deicing technology, and steam deicing technology.…”

Using deicing fluids is the main way of aircraft ground deicing, which plays an important role in ensuring flights’ safety. However, most of the airports use deicing fluids excessively to ensure the quality and efficiency of aircraft ground deicing, which will not only cause a large amount of deicing fluids wasted but also pollute water resources and the environment. Finding the optimal solution between deicing efficiency and deicing fluids consumption through effective methods is necessary. This article analyzes the energy conversion process of aircraft ground deicing, establishes multi-parameter optimization model for deicing, and optimizes the consumption of deicing fluids. The physical quantity, including the flow rate and the temperature of deicing fluids, is found as the main influence of the deicing time, which is the most concerned problem in the actual operation. Under the precondition of ensuring the deicing efficiency, the optimized parameters such as different ambient temperature, wing area, and icing thickness are obtained by genetic algorithm. The trend between the parameters with the change of environment has also been analyzed. Finally, the actual using condition in the capital airport and the optimized results are compared, and the results show that the usage of deicing fluids reduced 13% to 24%.

“…The role of ground support work of aircraft becomes significant important with the development idea "Security, Efficiency, Green" in our civil aviation field. The ice or snow on ground that can reduce the lifting power when taking off and damage the structure block of aircraft [1] . In this case, FAA demands that the ice or others on the surface of aircraft must be cleared up before takeoff.…”
