“…For example, metallic screens can create false targets for surface surveillance radars. At the same time, the limitations of sensitive or critical areas for multiple devices also pose challenges for siting metallic visual screens [90,92]. As a result, the global use of metallic visual screens is not widespread.…”

“…Analyses were also conducted on the impact of visual screens at different locations on the ILS system. According to the simulation result, the visual screen mainly affects the glide path antenna signal, and the distance between the screen and glide path antenna should be greater than 800 m [92]. Before installation, the possible influence of a screen on the signal of the glide path should be analyzed.…”

Hub airports typically have multiple parallel runways, requiring aircraft to transfer between them. This increases the risk of runway incursions. End-around taxiways (EATs) mitigate such risk by enabling bypassing without runway crossings. This review summarizes 15 EAT layouts worldwide and presents two classification methods: by configuration (N-type, M-type, Large N-type) and by operational relationship with runways (back-around, runway end-around, start-around). The key benefits of EATs were manifold, including the reduction of runway incursions, controller workload, and delays while improving communication safety, capacity, and efficiency. However, drawbacks such as increased land use, construction costs, and potentially longer taxi times and distances should be considered. Therefore, the optimization of the EAT layout is essential. In pursuit of optimal design, considerations should encompass limiting obstacle surfaces, flight procedures, navigation/lighting facilities, jet blast, and visual obstructions from end-around aircraft to departing aircraft. Notably, challenges arise in reducing distances between EATs and thresholds/ends. The given solutions include displacing thresholds, creating “sunken” lowered elevation EATs, and utilizing terrain shielding instead of metallic visual screens. A case study was introduced to demonstrate the successful improvement of the EAT via sunken EATs and terrain shielding at Guiyang Airport. The conclusion encourages further optimization of EAT layouts that balance safety and efficiency.

This paper is centered around the theoretical, experimental, and simulation analysis of safe passage redundancy and the mechanical deformation of the taxiway bridge under the fatigue accumulation state, and we define the redundancy as the remaining times that the aircraft can pass safely on the taxiway bridge. Based on the principle of stress control, the entity of the taxiway bridge was scaled to establish a laboratory model. The accuracy of the simulation model was verified by the comparative analysis between the experimental and the simulation data. The fatigue–life curve (S–N curve) was introduced to overlay the material fatigue state cycle into the simulation model of the taxiway bridge, and the safe passage redundancy and mechanical deformation of the bridge under the fatigue accumulation state were analyzed. By analyzing and processing the simulation data, a calculation model for the safe passage degree of the taxiway bridge under the fatigue state and a prediction calculation model for the remaining passage life were constructed. By comparing the simulation data with the model data, the accuracy of the established model was verified to be higher than 95%, which provides an important theoretical reference for the development of research on the safety life detection and evaluation of the subsequent taxiway bridge under the fatigue state.
