The potential hazard of one aircraft encountering the trailing vortex wake of another aircraft during either take-off or landing is well known. The wake vortex hazard in the terminal area has been virtually eliminated using the operational procedures and aircraft separation criteria mandated by the air traffic authorities. This paper presents arguments that wake encounters at cruise altitude ar...

Unmanned Aerial Systems (UAS) are a promising technology for many areas, including transportation, agriculture, inspection, and rescue missions. However, to enable high level of autonomy, Beyond Visual Line Sight (BVLOS) filght, the drones should be able perform safe landings in unknown areas without an operator. Hence there is need development landing methods autonomous drones. The UAVs can of...

Landing gear is a structural component of an aircraft to support the weight while it is on the ground and also to aid safe landing. A generic analytic model for linear dynamic analysis of landing gears, which captures responses of individual components, is seldom available in literature. In the present work an analytical model for the linear response analysis of landing gear is developed. The l...

With the availability of comprehensively integrated Airport Operational Databases, as motivated by the emergence of Collaborative Decision Making for example, new forms of automated information processing become available: Particularly, proactive Decision Support Systems can be developed based on the concepts of Artificial Intelligence. From various potential fields of application, this paper f...

Landing gear is an essential part of aircraft. However, the components landing are susceptible to degradation over life their operation, which can result in shimmy effect occurring during take-off and landing. In order reduce unplanned flight disruptions increase availability aircraft, predictive maintenance (PdM) technique investigated this study. This paper presents a case study on implementa...

Unmanned aerial vehicles (UAVs) are increasingly replacing manned systems in situations that are either too dangerous, too remote, or too difficult formanned aircraft to access. Modern UAVs are capable of accurately controlling their position and orientation in space using systems such as the Global Positioning System (GPS) and the Attitude and Heading Reference System (AHRS). However, they are...

Relative navigation of an aircraft (fixed wing or helicopter) close to ships at sea is a unique navigation problem. Shipboard helicopter operations provide a difficult operational environment. Wind over deck and wake turbulence shed by ship super structure offer challenging and unpredictable conditions during takeoff and landing. This is especially true in the operational environment that inclu...
