Uncontrolled Airspace

It may come as a surprise that there are many
different classes of airspace and if you plan to attend our aeronautics school, you will need to learn
them. To begin, there is a difference between uncontrolled airspace and
controlled airspace. Uncontrolled airspace refers to space in the air that is
not monitored or controlled by Air Traffic Control (ATC).

Class
G airspace is the only uncontrolled airspace class in the United States. In the
simplest form, class G airspace is leftover airspace that does not fit into one
of the other airspace classes. In this area, you do not need air traffic
control clearance, but there are still weather requirements and speed
restrictions for safety reasons. Class G airspace extends from ground level to
the bottom of airspace E which is discussed in more details below.

Controlled Airspace Classes

The other airspace categories qualify as controlled
airspace. Controlled airspace is an area in the sky that air traffic control
does have authority over.

Class A Airspace
The first of the airspace classes is class A. Class A airspace requires instrument
flight rules. This area extends from 18,000 feet mean sea level (MSL) up to
flight level 600 and out to 12 nautical miles from the contiguous United
States.

Class B
Airspace
– This designated area starts at ground level and goes up to
100,000 MSL. This class of airspace is used around busy airports.

Class C
Airspace
– Class C airspace also starts at the ground but extends to 4,000
feet about the airport elevation. This airspace class is also used around
airports that meet certain standards. Pilots must get permission via radio to
enter this airspace.

Class D
Airspace
– The area from the surface to about 2,500 feet above the airport
elevation is considered class D airspace. This class surrounds airports with an
operational control tower. Radio approval from ATC is required to enter this
area as well.

Class E Airspace– Class E is a large portion
of airspace in the country and basically includes the leftover controlled
airspace that does not fit into another class.

Special Use Airspace

Special
use airspace is used for areas where there are strict limitations on aircraft
operations. Special use airspace includes restricted areas, military operation
areas, warning areas, alert areas, and controlled firing areas.

Other Airspace Classes

Other
airspace is another way to categorize the leftover space not already meeting the
requirements for the other different classes of airspace. Some of the other airspace
includes areas like temporary flight restrictions, national security areas,
local airport advisor, military training route, and parachute jump aircraft
operations.

If
you find this information interesting, then you should consider attending an aircraft dispatcher school like
ours and getting your aircraft dispatcher license. At Sheffield
School of Aeronautics, we will not only go into this information is more depth
but also open your eyes to a world of new information.
