(4 marks) what factors make it a system accident in the Russian plane and Cargo’s mid-air collision? (explain them in the context of the accident).

should use the following systems characteristics to explain the systems accident:

· Proximity: planes were too close together in the air corridor

· Tight coupling: due to speeds and altitude,

· Non-linear systems relations between ATC + 2 planes,

· Complex automated situation

· Not reversible

· Common mode ATC --à 2 planes

There may be other reasonable points as well.
