The operation safety of the civil aircraft at plateau airports is a hot topic in civil aviation. In the terminal area of plateau airports, the navigation performance of the aircraft is easily affected by complex terrain and varied climate, and the single sensor’s altitude information is unreliable, which threatens flight safety. Therefore, in order to guarantee the safety and reliability of civil aircrafts in vertical direction under the complex environment, this paper constructed a unified model of altitude datum for heterogeneous sensors and proposed a relative/absolute altitude fusion method based on terrain state recurrence and barometric altitude assistance. It sets terrain height to a state and integrates atmospheric data system and radio altimeter with inertial navigation system simultaneously, which improves the vertical accuracy and estimates the terrain height effectively. In conclusion, this method can ensure the vertical safety of the civil aircraft flying under the complex environment of plateau airports. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Characteristics of runoff and sediment yield for two typical erodible soils in southern China

International Journal of Sediment Research 2022年第5期37卷 653-661页

Granite red soil(GRS) and Quaternary red clay(QRC) are two typical erodible soils in the red-soil region of southern China. Analytical and comparative studies of the characteristics of runoff and sediment yield for the two soils at various slopes are currently needed. The purpose of the current study was to clarify the characteristics of runoff and sediment yield for GRS and QRC at different slopes and to establish models for estimating sediment yield for the two soils. Forty-eight runoff microplots with four slopes(5°, 15°, 25°, and 35°) and two soils(GRS and QRC) were established and exposed to natural rainfall. Runoff and sediment yield were measured 10 times during the study period. Runoff and sediment yield for the two soils under the various slopes had similar temporal variations, and both increased with prior cumulative erosive rainfall. Runoff for GRS and QRC was moderately temporally variable, with coefficients of variation(CVs) from 46.2% to 60.6%, and sediment yield for QRC was strongly temporally variable, with CVs from 114.8% to 145.8%. Sediment yield for GRS increased with slope, but sediment yield for QRC first increased and then decreased, with a calculated inflection point of 18°, but runoff for both soils decreased with slope. The CVs of both runoff and sediment yield with slope for the two soils ranged from 3.6% to 88.0%, lower than the temporal variabilities, indicating that rainfall may have a larger impact than slope on runoff and sediment yield for QRC and GRS. Under the various slopes, runoff and sediment yield for both soils increased with rainfall and sediment yield increased with runoff, but the proportions of effective rainfall and runoff differed. Pedotransfer-function models based on rainfall, runoff, and slope accurately estimated sediment yield for the two soils, with the model fit coefficient of determination(R2) > 0.81 and the R2for verification >0.79. These results improve the understanding of the laws governing erosion for differe
