skybrary supports improved safety risk awareness and mitigation by offering insight into the main safety hazards, such as loss of control, cfit, loss of separation and mid-air collision, runway excursion, runway collision, in-flight fire, airspace infringement, air-ground communication failures, drones and ground collision. skybrary articles describe the aviation safety hazards in terms of causal and contributory factors, effects on safety aircraft operations and humans, safety barriers and risk mitigation solutions. primary focus is the operational safety improvement in the domains of air traffic management, flight operations and human performance. however, safety management, safety promotion and sharing of safety knowledge, safety improvement tools and safety regulation have been addressed, too.
