SMS Most Wanted

Image
A safety management system includes a list of the ten most wanted fugitive hazards and they are on the run. The most wanted hazards are identifiable hazards, but airports or airlines are unable to locate the whereabouts of their solutions. Hazards are locally different in the operational environment of airport or aircraft operation based on locations, destinations or flight conditions and require an operating environment specific safety risk management system applied.  Conventional wisdom is that hazard is a condition, when left unattended becomes a risk that foreseeable could cause harm to personnel or contribute to an incident or accident. The person managing a safety management system (SMS) has an obligation to identify hazards and carry out risk management analyses of those hazards. When the whereabout of hazards are unknown there are no requirements to carry out risk management. Make sense. The person managing the SMS is also responsible for implement a reporting system to ensure

Elevated Runway Edge Lights By Inversion

Image
When operating in the arctic, subarctic, mountainous areas, or sparsely settled areas, airlines and airports needs a safety management system (SMS) that includes optical illusion by inversion, optical illusion by sun angle, and optical illusion known as the black-hole effect. An optical illusion is real and the same as a mirage. A mirage is a real optical phenomenon that can be captured on camera since light rays are actually refracted form the false image. A mirage occurs when there is a temperature inversion. An inversion is when air at higher altitudes is warmer than the air below. When the air below the line of sight is colder than the air above it and when passing through the temperature inversion, the light rays are bent down, and so the image appears above the true object. Mirages tend to be stable, as cold air has no tendency to move up and warm air has no tendency to move down. Mirages make objects below the horizon, or outside of a normal line of sight, visible at the horizon
