Separation
Aircraft separation is divided up into the Protected Zone and the Alert Zone. In the larger zone, called the "alert zone", the system informs the aircraft through one of the three approaches that an aircraft is in the vicinity. It acts as a flag and merely alerts the aircrew. In the protected zone, the area must remain sterile of all foreign objects. It is the minimum distance anything can approach. The system should alert the aircrew before anything comes close to it but if it manages to enter the protected zone aircrew will take evasive maneuver to avoid a collision.

Famous quotes containing the word separation:
“Just as children, step by step, must separate from their parents, we will have to separate from them. And we will probably suffer...from some degree of separation anxiety: because separation ends sweet symbiosis. Because separation reduces our power and control. Because separation makes us feel less needed, less important. And because separation exposes our children to danger.”
—Judith Viorst (20th century)
“Like sleep disturbances, some worries at separation can be expected in the second year. If you accept this, then you will avoid reacting to this anxiety as if it’s your fault. A mother who feels guilty will appear anxious to the child, as if to affirm the child’s anxiety. By contrast, a parent who understands that separation anxiety is normal is more likely to react in a way that soothes and reassures the child.”
—Cathy Rindner Tempelsman (20th century)
“Last evening attended Croghan Lodge International Order of Odd Fellows. Election of officers. Chosen Noble Grand. These social organizations have a number of good results. All who attend are educated in self-government. This in a marked way. They bind society together. The well-to-do and the poor should be brought together as much as possible. The separation into classes—castes—is our danger. It is the danger of all civilizations.”
—Rutherford Birchard Hayes (1822–1893)
