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:
“Nature seems to have taken a particular Care to disseminate her Blessings among the different Regions of the World, with an Eye to this mutual Intercourse and Traffick among Mankind, that the Natives of the several Parts of the Globe might have a kind of Dependance [sic] upon one another, and be united together by their common Interest.”
—Joseph Addison (1672–1719)
“We have wasted our spirit in the regions of the abstract and general just as the monks let it wither in the world of prayer and contemplation.”
—Alexander Herzen (1812–1870)
“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)
