1. U.S. AIRSPACE

2. There are 6 basic types of airspaces in the U.S. Airspace system?
A B C D E G

4. Class A: All operations must be conducted under Instrument Flight Rule (IFR) or Special Visual Flight Rules (SVFR).[1] All aircraft are subject to ATC clearance. All flights are separated from each other by ATC. Aircraft flying in Class A airspace are required to be IFR-equipped and have DME if flying above FL240. This airspace is managed by Air Route Traffic Control Centers (ARTCCs)

5. What are the lateral dimensions of Class A Airspace?
Class A airspace lies over the 48 contiguous states and Alaska, including airspace overlying waters within 12 NM of the coast.

6. What are the vertical dimensions of Class A Airspace?
Class A airspace vertical limits are 18,000 feet MSL to FL 600. In Alaska, excludes airspace below 1500 AGL.

8. Class B Airspace

9. Class B: Surrounds major hub airports with heavy traffic operations
Class B: Surrounds major hub airports with heavy traffic operations. This airspace is layered, generally in the form of an upside-down wedding cake, so that it surrounds all aircraft approaching or departing from the airport up to 10,000 feet MSL. Operations may be conducted under IFR, SVFR, or Visual flight rules (VFR). All aircraft are required to receive an ATC clearance prior to entering Class B airspace. All flights are separated from each other by ATC. Required onboard equipment includes one VOR navigation unit. This airspace is managed by the approach/departure control facility linked to the airport with which the airspace is conjoined. (Cleveland KCLE)

10. Class B airspace is the most congested and the biggest airspace
. Class B airspace is the most congested and the biggest airspace. You have to have certain specifications to be able to fly in class B airspace. These are: You must have a 2 way radio, to be able to have constant communication with ATC so you can stay updated with incoming aircraft and such. Also, you must have a mode C transponder(a mode C transponder is required in class A,B, and C airspace). This allows the ATC to see your current altitude. Class B airspace has been known as a sort of an upside down cake like airspace because of its shape (a circle).

11. What are the lateral dimensions of Class B Airspace?
The lateral boundaries of Class B airspace are individually tailored. There are no special dimensions. The airspace consists of at least 2 layers.

12. What are the vertical dimensions of Class B Airspace?
Class B airspace extends from the surface to generally 10,000 feet MSL. Each layer has its own defined vertical limit.

13. What are the minimum cloud and visibility requirements within Class B Airspace?
Minimum weather requirements for Class B Airspace are: 3 miles visibility Clear of clouds

14. What are Class B Airspace communications requirements?
Must have positive ATC clearance prior to entry or departure from airspace. For IFR operations, must have VOR or TACAN.

15. What is the Class B Airspace transponder requirement?
Aircraft must have a transponder with Mode - C.

16. What is the Mode - C veil?
The mode-C Veil is the airspace within 30 NM of the Class B airport in which a transponder with Mode-C is required. Active from surface to 10,000 feet MSL. The Veil is denoted on VFR charts by a thin blue line.

17. How is Class B airspace charted on a VFR sectional map?
Class B airspace is charted on a VFR sectional by a series of blue circles.

19. Class C Airspace

20. Class C: Operations may be conducted under IFR, SVFR, or VFR
Class C: Operations may be conducted under IFR, SVFR, or VFR. Entering Class C airspace only requires radio contact with the controlling air traffic authority, but an ATC clearance is ultimately required. Aircraft operating under IFR and SVFR are separated from each other and from flights operating under VFR. Flights operating under VFR are given traffic information in respect of other VFR flights. Operations from the primary airport or satellite airport with an operating control tower must establish and maintain two-way radio communications with the control tower. This airspace is managed by the approach/departure control facility linked to the airport with which the airspace is conjoined. (CAK)

21. What are the lateral dimensions of Class C Airspace?
Class C airspace has 2 circles centered on the airport: The inner circle has a radius of 5 NM The outer circle has a radius of 10 NM

22. What are the vertical dimensions of Class C Airspace?
Generally the inner circle starts at the surface up to 4000 Feet AGL The outer circle starts at 1200 Feet AGL up to 4000 Feet AGL

23. What are the minimum cloud and visibility requirements within Class C Airspace?
Minimum weather requirements for Class C Airspace are: (152) Distance from clouds 1000 feet above 500 Ft below 2000 Ft horizontally. Minimum Visibility = 3 SM

24. What are Class C Airspace communications requirements?
You must establish communications with ATC prior to entry.

25. What is the Class C Airspace transponder requirement?
Aircraft must have a transponder with Mode - C within and above all Class C airspace, up to 10,000 Ft MSL.

26. What is the outer area of Class C airspace?
The outer area is not part of Class C airspace. The outer area has a radius of 20 NM from the airport. It starts at the lower limit of radio/radar coverage and goes up to the upper limit of Approach Control’s delegated airspace.

27. How is Class C airspace charted on a VFR sectional map?
Class C airspace is charted on a VFR sectional by two magenta circles.

28. Class C Airspace

29. Class D Airspace

30. Class D: Operations may be conducted under IFR, SVFR, or VFR
Class D: Operations may be conducted under IFR, SVFR, or VFR. All flights are subject to ATC clearance. Aircraft operating under IFR and SVFR are separated from each other, and are given traffic information in respect of VFR flights. Flights operating under VFR are given traffic information in respect of all other flights. The controlling authority for this airspace is the control tower for the associated airport, and radar may or may not be used. County (CGF) / Mansfield (MFD)

31. What are the lateral dimensions of Class D Airspace?
Class D airspace is normally a 5 SM radius from the airport. Some airports may have extensions protruding from the circle.

32. What are the vertical dimensions of Class D Airspace?

45. What are Class E transition areas and what altitudes do they start at?
A. Class E airspace that is used to transition to/from the terminal or enroute environment is called a transition area. A fading magenta color on a VFR sectional denotes a transition area starting at 700 Ft AGL. A fading blue color on a VFR sectional denotes a transition area starting at 1200 Ft AGL. However, the blue color is not shown unless it abuts uncontrolled Class G airspace.

48. Airports with Class E surface areas
Airports with Class E surface areas can have a fair amount of traffic, and may or may not have a way to reach people on the ground. Look for an RCO (remote communications outlet).
A RCO on the field can be set up to reach FSS or ATC.
