AIRSPACE CLASSIFICATIONS QUESTIONS AND
ANSWERS 100% CORRECT
Controlled Airspace - ANSWER The different classifications of airspace and
defined dimensions within which air traffic control (ATC) service is provided in
accordance with the airspace classification.
Class A
18,000' - 60,000' MSL.
En route, high-altitude environment used by IFR aircraft to transit from one area
of the country to another.
sUAS flights are prohibited
Class B Airspace - ANSWER Established around very large major airports; two-
way radio communication.
Surface to 10,000 feet MSL.
Surrounds the nation's busiest airports.
Consists of a surface area and two or more additional layers.
Memory Key: Big & Busy
Class C airspace - ANSWER Class C area is individually tailored, the airspace
usually consists of a surface area with a 5 NM radius, an outer circle with a 10 NM
radius that extends from 1,200 feet to 4,000 feet above the airport elevation.
, A remote pilot must receive authorization before operating in Class C airspace.
Surrounds airports with airport traffic control towers and radar approach control
Typical Dimensions
5-mile radius from surface to 4,000' AGL
10-mile radius shelf from 1,200' to 4,000' AGL
Memory Key: Controlled
Class D Airspace - ANSWER Class D airspace is generally airspace from the
surface to 2,500 feet above the airport elevation (charted in MSL) surrounding
those airports that have an operational control tower.
Class D airspace area is individually tailored and, when instrument procedures are
published, the airspace is normally designed to contain the procedures. A remote
pilot must receive ATC authorization before operating in Class D airspace.
When Class D airports that's are part-time are not in operation, the airspace turns
into Class E, or G airspace.
I. Surrounds airports with operational control tower
II. Radius is individually tailored and normally designed to contain any published
instrument procedures
III. Extends upward from the surface to 2,500 feet above airport elevation
IV. Memory Key: Discuss
