Regions
The regions are broken up into unrestricted, transition, and restricted.
Unrestricted - In the unrestricted region there will be very little guidance from ATC since aircraft density will be low. Pilots will have a great deal of flexibility to exercise free flight in this area. However, it may become complicated when bad weather is calculated into the equation. Pilots may have to adjust their course to avoid inclement weather. In doing so other pilots attempting to avoid the conditions may cross path with each other. ATC will have to assist the pilots and guide them through this issue.
Transition – Slightly restricted however pilots retain some flexibility to exercise free flight.
Restricted - The freedom of the pilot has been restricted significantly.

Famous quotes containing the word regions:
“Within the regions of the air,
Compassed about with heavens fair,
Great tracts of land there may be found
Enriched with fields and fertile ground;
Where many numerous hosts
In those far distant coasts,
For other great and glorious ends,
Inhabit, my yet unknown friends.”
—Thomas Traherne (1636–1674)
“It is doubtful whether anyone who has travelled widely has found anywhere in the world regions more ugly than in the human face.”
—Friedrich Nietzsche (1844–1900)
“What is a television apparatus to man, who has only to shut his eyes to see the most inaccessible regions of the seen and the never seen, who has only to imagine in order to pierce through walls and cause all the planetary Baghdads of his dreams to rise from the dust.”
—Salvador Dali (1904–1989)
