Study Notes

Class A Airspace

Extends from 18,000 feet MSL and all operations are conducted under IFR.
VFR minimums for visibility and cloud distance are not applicable.

Class B Airspace

Covers from ground up to 10,000 feet MSL surrounding busy airports.
Requires ATC clearance to enter; acknowledged with "Cleared thru Bravo."
VFR minimums: 3 statute miles visibility, clear of clouds.

Class C Airspace

Ranges from the surface to 4,000 feet above airport elevation, often shaped with a 5 NM surface area radius and a 10 NM outer radius.
Mandatory two-way radio communication; full call sign used for entry.
VFR minimums: 3 statute miles visibility, 1,000 feet above, 500 feet below, and 2,000 feet horizontal from clouds.

Class D Airspace

Extends from surface to 2,500 feet above airport elevation.
Requires two-way communication for directions to enter.
VFR minimums: 3 statute miles visibility, 1,000 feet above, 500 feet below, and 2,000 feet horizontal from clouds.

Class E Airspace

Begins at 14,500 feet MSL if no other class is indicated; bases often at 1,200 feet or 700 feet AGL.
VFR minimums vary:
- At or above 10,000 feet: 5 statute miles visibility, 1,000 feet above, 1,000 feet below, 1 statute mile horizontal.
- Below 10,000 feet: 3 statute miles visibility, 1,000 feet above, 500 feet below, 2,000 feet horizontal.

Class G Airspace

Extends from the surface to the base of overlying Class E airspace, typically 700 or 1,200 feet.
ATC has no control authority.
Daytime VFR minimums vary with altitude, generally requiring more strict visibility and distance from clouds regulations than at night.

Special Use Airspace (SUAs)

Defined areas where specific activities occur or operations are limited.
Includes prohibited areas, restricted areas, warning areas, military operation areas (MOAs), alert areas, and controlled firing areas (CFAs).

Prohibited Areas

Denoted with a "P" followed by a number (e.g., P-40).
Flight prohibited due to security concerns, such as around national landmarks.

Restricted Areas

Indicated with an "R" followed by a number; risky operations present hazards to nonparticipating aircraft.
Entry may be permitted if not active and authorized by ATC.

Warning Areas

Charted with a "W" followed by a number (e.g., W-237).
Extends from the U.S. coast; may contain hazardous activities to nonparticipating aircraft.

Military Operation Areas (MOAs)

Airspace defined for military training to separate it from IFR traffic.
Nonparticipating aircraft may transit if IFR separation is ensured.

Alert Areas

Indicated by an "A" followed by a number (e.g., A-211); caution advised due to high training activity.

Local Airport Advisory (LAA)

Provided by Flight Service Stations; offers local advisories and weather reports using designated frequencies.

Military Training Routes (MTRs)

Established for military aircraft training, usually under 10,000 feet MSL at speeds exceeding 250 knots.
Denoted as IFR (IR) or VFR (VR) routes; marked with identifying numbers.

Temporary Flight Restrictions (TFR)

Issued via FDC NOTAMs to restrict aircraft from flying in certain areas temporarily, commonly for security purposes post-9/11.

Published VFR Routes

Designed for navigating complex airspace transitions, known by terms like VFR flyway or transition route.

Terminal Radar Service Areas (TRSAs)

Areas where VFR pilots can receive enhanced radar services; participation is optional but recommended.

National Security Areas (NSAs)

Defined airspace requesting voluntary avoidance to enhance security; may have temporary prohibitions.

Basic VFR Weather Minimums

Pilots prohibited from flying under VFR in certain visibility conditions; 14 CFR part 91 outlines specific requirements.

Controlled Firing Area (CFA)

Activities are coordinated to eliminate hazards to nonparticipating aircraft and ensure safety.

Parachute Jump Aircraft Operations

Information published in the Chart Supplement U.S.; frequently used sites indicated on sectional charts.
