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.
