Airspace Classes Flashcards
A Remote PIC should be able to demonstrate knowledge of
General controlled airspace
Special use airspace
Other airspace areas
Air Traffic Control (ATC) and the National Airspace System (NAS)
Regulatory airspace is defined as…
Class A, B, C, D and E airspace
areas, Special Use Airspace (SAU), such as Restricted Areas and
Prohibited Areas
Non-regulatory airspace is defined as…
Military Operating Areas,
Warning Areas, Alert Areas and Controlled Firing Areas
What are the categores and types of airspace dictated by?
The categories and types of airspace are dictated by the complexity
or density of aircraft movements, nature of the operations conducted
within the airspace, the level of safety required, and national and
public interest.
What are the 5 class of Airspace?
Class A
Class B
Class C
Class D
Class E
Class A defined as?
Class A is defined as the airspace from 18,000 feet mean sea level
(MSL) up to and including flight level 60,000 feet
What airspace can you fly unrestricted?
Class G
Class B defined as
Class B airspace is defined as airspace from the surface to 10,000 Ft
MSL surrounding the nation’s busiest airports in terms of airport operations or passenger enplanement
What Airspace has a thick solid blue line?
Class B
How many layers does the class B airspace have
3 - upside down cake
Surface layer and two or more layers
What clearance do you need for operation in a class B airspace?
ATC (Air Traffic Control) clearance required in Class B airspace.
Class C defined as?
Class C airspace is defined as airspace from the surface to 4,000 feet above the airport elevation (charted in MSL) surrounding those airports that:
Are crowded or congested
Have an operational control tower
Are serviced by a radar approach control
Have a certain number of IFR operations or passenger enplanements
What is the elevation for Class C airspace
surface to 4,000 feet
A Thick magenta line is what airspace?
Class C
What must an aircraft have for class C airspace?
- must establish 2 day radio communication with ATC. maintain while within airspace
What is a class D airspace?
Class D airspace is defined as airspace from the surface to 2,500 feet above
the airport elevation (charted in MSL) surrounding those airports that have
an operational control tower (may not be operational 24/7)
A dashed blue line is what airspace?
Class D
Does a sUAS need to recieve authorization for opporating in a Class D airspace?
Yes
sUAS operations must receive authorization before operating in Class D
airspace
Class E is defined as ?
Class E airspace extends upward from either the surface or a designated altitude
to the overlying or adjacent controlled airspace.
A thick magenta shaded boundary (700) or a thick blue shaded boundry (1,200 ft) is what airspace?
Class E
Class G Airspace is defined as?
Uncontrolled airspace, portion of the airspace not designated as Class A, B, C, D, or E
Does the remote pilot need ATC authorization to operate in Class G airspace?
No! Don NOT need authorization
What is Special Use Airspace?
Special use airspace is defined as airspace in which certain activities must be confined, or
where limitations may be imposed on aircraft operations that are not part of those activities
What is Prohibited Airspace
Prohibited areas contain areas were the flight of aircraft is prohibited for security or other reasons tied to national welfare
Restricted Airspace
Restricted areas are where operations are
hazardous to non participating aircraft and
while flight in the area is not entirely prohibited,
it is subject to restrictions
What is a Warning Area?
Warning areas are similar to
restricted areas however the U.S. government does not have
complete control of the airspace
What is a Military Operation Area?
MOAs are established to allow
military training activities like high
speed flight, low level flight or
even lights out night training
What are Military training Routes
MTRs with 4 numbers
denote routes flown at
1,500 AGL and below
MTRs with 3 numbers
denote route flown with
at least one segment
above 1,500 AGL
