Answer 1

regulatory and nonregulatory

Question 2

Answer 2

controlled, uncontrolled, special use, and other airspace

Question 3

Answer 3

Class B, C, D, and E

Question 4

Class B Airspace

Answer 4

airspace from the surface to 10,000 feet mean sea level (MSL)

Question 5

Answer 5

Class E and G

Question 6

Class C Airspace

Answer 6

airspace from the surface to 4,000 feet MSL

Question 7

Class D Airspace

Answer 7

airspace from the surface to 2,500 feet MSL

Question 8

Class E Airspace

Answer 8

controlled airspace not classified as Class A, B, C, or D airspace; large amount of airspace over US; 1200 feet AGL to 18000 feet MSL

Question 9

Federal Airways are shown as what color lines on a sectional chart and are usually found in within what airspace class?

Answer 9

Blue lines; Class E

Question 10

Uncontrolled Airspace

Answer 10

Class G; airspace not designated by Class A, B, C, D, or E; extends from surface to base of Class E airspace

Question 11

Special Use Airspace

Answer 11

Special Area of Operation (SAO); designation for airspace in which certain activities must be confined

Question 12

Special use airspace usually consists of:

Answer 12

• Prohibited areas
• Restricted areas
• Warning areas
• Military operation areas (MOAs)
• Alert areas
• Controlled firing areas (CFAs)

Question 13

Prohibited Areas

Answer 13

airspace of defined dimensions within which the
flight of aircraft is prohibited; charted as “P” followed by a number; established for security or
other reasons associated with the
national welfare

Question 14

Restricted Areas

Answer 14

areas where operations are hazardous to
nonparticipating aircraft and contain
airspace within which the flight of aircraft is subject to
restrictions; charted as “R” followed by a number

Question 15

Warning Areas

Answer 15

airspace of defined dimensions,
extending from 3 NM outward from the
coast of the United States, containing
activity that may be hazardous to
nonparticipating aircraft; designated with a “W” followed by a number

Question 16

Military Operation Areas (MOAs)

Answer 16

airspace with
defined vertical and lateral
limits established for the
purpose of separating certain
military training activities from
IFR traffic

Question 17

Alert Areas

Answer 17

inform nonparticipating pilots of areas that may contain a high volume of pilot training or an
unusual type of aerial activity; depicted on aeronautical charts with an “A” followed by a number

Question 18

Controlled Firing Areas (CFAs)

Answer 18

contain activities that, if not conducted in a controlled environment, could be hazardous to
nonparticipating aircraft

Question 19

What is the difference between CFAs and other special use airspace?

Answer 19

activities must be suspended when a spotter aircraft, radar, or ground lookout position indicates an
aircraft might be approaching the area

Question 20

Local Airport Advisory (LAA)

Answer 20

an advisory service provided by Flight Service facilities, which are located on the landing airport,
using a discrete ground-to-air frequency or the tower frequency when the tower is closed

Question 21

Military Training Routes (MTRs)

Answer 21

routes used by military aircraft to maintain proficiency in tactical flying; usually established below 10,000 feet MSL for operations at speeds in excess of 250 knots; identified as IFR (IR), and VFR (VR), followed by a number

Question 22

Temporary Flight Restrictions (TFRs)

Answer 22

provided in a flight data center (FDC) Notice to Airmen (NOTAM);

protect persons and property in the air or on the surface from an existing or imminent
hazard

provide a safe environment for the operation of disaster relief aircraft

prevent an unsafe congestion of sightseeing aircraft above an incident or event, that may
generate a high degree of public interest

protect declared national disasters for humanitarian reasons in the State of Hawaii

protect the President, Vice President, or other public figures

provide a safe environment for space agency operations.

Question 23

What is the primary purpose of the ATC system?

Answer 23

to prevent a collision between aircraft operating in the

system and to organize and expedite the flow of traffic

Question 24

Notices to Airmen (NOTAMs)

Answer 24

contain current notices to airmen that are considered essential to
the safety of flight

ex. hazards, inoperable lights, passage of flocks, flights by important people, temp. erection of obstacles
