Airspace Classification Unit 4 Vocabulary Part 1

Study Notes

Advisory Circulars (ACs)

Informational documents created by the FAA for guidance within the aviation industry and general public.
Intended to be informative, not regulatory, but often recommend FAA actions.

Aeronautical Information Manual (AIM)

Official FAA guide covering basic flight information and Air Traffic Control (ATC) procedures.
Contains essential aeronautical knowledge needed for flying in the U.S. National Airspace System.

Airman Knowledge Testing Supplement

Supplementary book for FAA Knowledge Exams at computer testing centers.
Features full-color charts, referred to during exams for navigation and reference.

Airport/Facility Directory (A/FD)

Now known as Chart Supplement in the U.S., providing detailed information on airports and aviation facilities.
Covers both large and small airports along with related operational procedures.

AGL (Above Ground Level)

Refers to height measurements above the actual ground surface rather than mean sea level (MSL).

Alert Area

Designated airspace that alerts pilots to common activities in the area.
Generally allows for flight without restrictions unless it involves other controlled airspace.

Altimeter

An instrument that measures altitude relative to a fixed reference level.

ATC (Air Traffic Control)

Ground-based service managing aircraft on the ground and through controlled airspace.
Key objectives include collision prevention, traffic organization, and support for pilots in non-controlled airspace.

Chart Supplement U.S.

Civil Flight Information Publication updated every eight weeks by the FAA.
Contains data on public-use airports, navigational facilities, military facilities, and communications information.

Class A Airspace

Extends from 18,000 feet mean sea level (MSL) up to flight level 600.
All operations require Instrument Flight Rules (IFR); not depicted on maps but understood.

Class B Airspace

Encompasses airspace from the surface up to 10,000 feet MSL around major airports.
Requires ATC clearance for operations and provides aircraft separation services.

Class C Airspace

Extends from the surface to 4,000 feet above the airport elevation for controlled towers with radar approach.
Covers mid-size airports, requiring specified IFR operations or passenger enplanements.

Class D Airspace

(Definition incomplete; context suggests it surrounds smaller airports with control towers and different operational requirements.)
