Study Notes

Class A Airspace

Extends from 18,000 feet MSL up to FL 600
Includes airspace 12 nautical miles offshore from the continental US and Alaska

Class B Airspace

Ranges from surface to 10,000 feet MSL surrounding the busiest airports
Configured as a surface area with two or more layers, resembling an upside-down wedding cake
Requires ATC clearance to enter

Class C Airspace

Extends from surface to 4,000 feet MSL
Typically has a 5 nautical mile radius core area and a 10 nautical mile shelf area
Shelf area extends between 1,200 and 4,000 feet above the airport elevation

Class D Airspace

Extends from the surface to 2,500 feet MSL around controlled tower airports
Requires two-way radio communication to enter

Regulations Reference

Specific airspace dimensions and operational requirements can be found in the Code of Federal Regulations (CFR) (3-1-1)

Visual Flight Rules (VFR) Restrictions

No operation beneath the ceiling of controlled airspace when the ceiling is below 1,000 feet

Unmanned Free Balloon Operations

Cannot operate below 2,000 feet above the surface in Class B, C, D, or E airspace designated for an airport, unless authorized by ATC

Class B Airspace Operations

Generally extends from the surface up to 10,000 feet MSL around major airports, characterized by high IFR operations or passenger enplanements

Class C Airspace Characteristics

Typically from the surface to 4,000 feet MSL surrounding airports with control towers and radar approach controls

Speed Restrictions in Class C Airspace

Aircraft must not exceed 200 knots when operating at or below 2,500 feet within 4 nautical miles of a primary Class C airport

Class D Airspace Operational Limits

Ranges from surface to 2,500 feet MSL around airports with operational control towers

Class E Airspace Specifications

Extends upward from either the surface or a designated altitude, with no defined vertical limit up to 18,000 feet MSL

Federal Airways

Class E airspace areas that extend from 1,200 feet to just below 18,000 feet MSL unless specified otherwise

Special Use Airspace

Contains areas where activities are confined, imposing limitations to protect non-participating aircraft

Warning Areas

Airspace extending 3 nautical miles outward from the US coast, where hazardous activities could affect non-participating aircraft

Military Operating Areas (MOAs)

Defined airspace for separating military training activities from IFR traffic

Speed Authorization in MOAs

DOD aircraft may exceed 250 knots below 10,000 feet MSL in active MOAs

Alert Areas

Marked on aeronautical charts to indicate high volumes of pilot training or unusual aerial activity

Controlled Firing Areas (CFAs)

Areas where potentially hazardous activities can occur but are controlled to ensure safety for non-participating aircraft

Advisory Services

Three advisory type services available at selected airports to assist pilots
