Safety management systems (SMS) are widely accepted as a way of improving safety and are currently required by the aviation regulations. Safety training and education of all professionals in the aviation safety system is vital for the success of any safety management strategy. At the same time some of the terms in the field are not uniquely and consistently defined, e.g. hazard, threat, safety issue, risk, risk area to name a few. This could be confusing for the users of the SMS who are not required to be safety experts. In addition, the abstract nature of the safety concepts and system thinking combined with the formal language of the regulations makes catching and keeping the attention of the trainees a challenge. A methodology for aviation safety training was developed and studied. The first objective of the elaboration was to introduce the students gradually by building on tangible and actionable items as performance indicators and accident scenarios. The second objective was to connect the above material with the standard safety management framework as defined by the International Civil Aviation Organization (ICAO). The main emphasis was on understanding the fundamental concepts, notations and relationships through practice. The presented approach has demonstrated higher engagement and improved material mastery of the students.

This study introduces a high-resolution wind nowcasting model designed for aviation applications at Madeira International Airport, a location known for its complex wind patterns. By using data from a network of six meteorological stations and deep learning techniques, the produced model is capable of predicting wind speed and direction up to 30-minute ahead with 1-minute temporal resolution. The optimized architecture demonstrated robust predictive performance across all forecast horizons.

With the projected expansion of the general aviation sector and recent breakthroughs in sustainable aviation fuels (SAF), accurately measuring emissions from novel aircraft engines powered by SAF is paramount for evaluating the role of aviation industry in emission reduction trends and environmental consequences. Current SAF research primarily centers on low blend ratios, neglecting data on 100% SAF. This study bridges this gap by experimentally determining emissions indices for gaseous pollutants (CO, CO, HC, NOx), total particulate matter (PM) counts and sizes, and non-volatile particulate matter (nvPM) number and mass concentrations from a heavy-fuel aircraft piston engines (HF-APE) using hydroprocessed esters and fatty acids-derived SAF (HEFA-SAF), adhering to airworthiness-standard sampling and measurement protocols.

Understanding the kinematics of aerosol horizontal transport and vertical mixing near the surface, within the atmospheric boundary layer (ABL), and in the overlying free troposphere (FT) is critical for various applications, including air quality and weather forecasting, aviation, road safety, and dispersion modeling. Empirical evidence of aerosol mixing processes within the ABL during synoptic-scale events over arid and semiarid regions (i.e.

The great horned owl (Bubo virginianus) is a generalist predator that inhabits wide-ranging territories that are relatively stable throughout the year. These owls are also involved in a variety of human-owl conflicts, including killing of domestic poultry, predating colonially nesting seabirds and shorebirds, and pose a hazard to safe aircraft operations. Managing these conflict situations presents unique challenges as great horned owls are nocturnally active and occupy a wide range of habitats.
