guidance and control of aircraft in the landing phase imposes extra pilot work loads, hence application of automatic landing control systems is of great importance. in this study automatic landing control systems are introduced and an optimal landing control system is designed. the control system performance criteria are based on minimum control effort. the designed system is simulated for a tr...

In this paper, a Bayesian framework is used to infer HiRISE-equivalent rock density from CTX image features without needing to explicitly identify rocks. The statistical relationship between HiRISE rock density and CTX image features is modeled using Bayesian Networks. The model is enriched by including geological features—specifically, geomorphic units. The geomorphic units are identified by g...

Landing safety is a hot issue in civil aviation management. In order to fully mine the influence factors of hard landing flight data and effectively predict risk landing, random forest algorithm was introduced. Firstly, this paper qualitatively analyzed chose features model based on data. Secondly, gives quantitative analysis method importance Gini index. Finally, for dataset class-imbalanced, ...

BACKGROUND Basketball is the most popular sport among the U.S. Air Force (USAF) active duty population and causes a large number of lost-workday injuries. The purpose of this study is to describe how basketball injuries occur to allow development of effective countermeasures. METHODS This study used data derived from safety reports obtained from the USAF Ground Safety Automated System. Basket...

We propose an model-based approach to address safety and security assessment of a system architecture. We present an integrated process where system engineers design the model of the system architecture, safety and security engineers specify the propagation of failures and attacks inside each component of the architecture using their dedicated tool. They also define the failure modes that have ...

The issue of modernization the integrated lighting equipment for take-off and landing power supply system airports in Eastern Siberia to improve safety aircraft flights was considered

Engine malfunctions during helicopter flight poses a large risk to pilot and crew. Without a quick and coordinated reaction, such situations lead to a complete loss of control. An autonomous landing system is capable of reacting quickly to regain control, however current emergency landing methods focus only on the offline generation of dynamically feasible trajectories while ignoring the more s...
