• Mandatory: Operate transponder on Mode C inside and above Class C
• Mandatory: Maintain two-way radio communication inside Class C

Question 10

Class E – Surface-based

Answer 10

At designated airports without a CT

Exists when the operating CT shuts down, an approved weather observation system is in operation, and communications are available to the surface

Extensions to surface areas of other controlled airspace

Question 11

Class E – Aloft Areas

Answer 11

Inside of Magenta
Vignette = 700’ AGL Base

Outside of Magenta
Vignette = 1,200’

Question 12

Special VFR Requirements

Answer 12

ATC clearance required

Operating within the lateral boundaries of surface areas of controlled airspace designated for an airport when the weather is <1,000’ ceiling and/or visibility is <3 SM

Maintain clear of clouds and ½ mile vis unless higher minimums are required at the airfield (AR 95-1, para 5-5).

Question 13

TRSA Regulations

Answer 13

Per AIM Sect. 3-5-6, Terminal Radar Service Areas (TRSAs) are part of the radar service program at selected airports. The TRSAs do not fit into any of the U.S. airspace classes.

Primary airports become Class D airspace.

The TRSA will overlie other controlled airspace, usually Class E.

Question 14

TRSA Regulations

Operating Procedures

Answer 14

Contact ATC to use services.

Maintain basic VFR cloud clearance requirements for flight altitude.

Comply with ATC instructions.

Participation is not mandatory although it is highly encouraged.

Question 15

Special Use Airspace Regulations

Answer 15

Per AIM sect. 3-4-1, Airspace wherein activities must be confined because of their nature

Airspace wherein limitations are imposed upon A/C operations that are not part of said activities

Both of the above

Question 16

Special Use Airspace Regulations

Prohibited Area

Answer 16

Established for national security reasons

Flight within this area prohibited

Designated with letter symbol “P” and number designator

Question 17

Special Use Airspace Regulations

Restricted Area

Answer 17

Denotes the existence of unusual, often invisible hazards such as aerial gunnery, artillery, or missile firing

Advance permission required

Designated with letter symbol “R” and number designator

Question 18

Special Use Airspace Regulations

Warning Area

Answer 18

Denotes airspace extending 3 NM outward from the coast of the U.S. that contains activity that may be hazardous to nonparticipating A/C

A/C cannot be restricted from entry, since area is over waters (domestic or international).

Designated with letter symbol “W” and number designator

Question 19

Special Use Airspace Regulations

Alert Area

Answer 19

Alerts pilots to high volume of pilot training or unusual activity within the area

No restrictions on through flight

Pilots responsible for collision avoidance

Designated with letter symbol “A” and number designator

Question 20

Special Use Airspace Regulations

Military Operations Area (MOA)

Answer 20

MOAs are established for the purpose of separating certain military training activities from IFR traffic.

DOD has been issued an authorization to operate A/C at indicated airspeeds in excess of 250 KTS below 10,000 MSL within active MOAs.

Military pilots have an exemption from CFR 14 part 91.303(c) and (d) which prohibits aerobatic flight.

Examples of MOA activities: air combat tactics, air intercepts, aerobatics, formation training, and low-altitude tactics

NO RESTRICTIONS to through-flight

Designated with letter symbol “MOA” and name designator

Question 21

Special Use Airspace Regulations

Air Defense Identification Zone (ADIZ)

Answer 21

Airspace within which the identification, location, and control of A/C are required for national security

VFR traffic flying into the ADIZ must file a Defense VFR (DVFR) flight plan.

Designated with magenta line and magenta dots with the words “Air Defense Identification Zone”

Question 22

Temporary Flight Restriction areas

Answer 22

Areas with Temporary Flight Restrictions are not shown on printed charts.

It is the aviator’s responsibility to be aware of TFRs along the route of flight.

Provide a safe environment for the operation of disaster relief A/C

Normally limited to within 2,000’ AGL and within a radius of 3 NM

Flight within disaster areas permitted only if part of the rescue effort or carrying members of the press

Protect people and property from existing or imminent hazards

Prevent unsafe congestion of sightseeing A/C

Protect VIPs

Protect space agency operations

Question 23

TFR Areas Regulations

Possible Health Hazards

Answer 23

Flying in TFRs could be hazardous to your health!

Possible causes of TFRs include toxic gas leaks, fires, volcanic eruptions, nuclear accidents, and hijackings.

Question 24

VFR cruising altitude rule

Answer 24

Above 3,000 ft AGL

0 to 179 odd thousands plus 500 (ex. 3500)

180 to 359 even thousands plus 500 (ex. 4500)

Question 25

Oxygen will be used by aircraft crews and occupants for flights as follows:

Answer 25

On flights above 10,000 feet pressure altitude for more than 1 hour.

On flights above 12,000 feet pressure altitude for more than 30 minutes.

(2) Aircraft crews and all other occupants.

On flights above 14,000 feet pressure altitude for any period of time.

For flights above 18,000 feet pressure altitude, oxygen prebreathing will be accomplished by aircrew members. Prebreathing may utilize either 100 percent gaseous aviator’s oxygen from a high-pressure source or an onboard oxygen generating system that supplies at least 90 percent oxygen. Prebreathing will be for not less than 30 minutes at ground level and will continue while en route to altitude. In those extraordinary cases where mission requirements dictate rapid ascent, commanders may authorize shorter prebreathing times on a case-by-case basis, with the realization that such prac-tice increases the risk of developing altitude decompression illness. Return to NORMAL OXYGEN (pressure demand regulator, gaseous oxygen-equipped aircraft) is authorized on descent below 18,000 feet pressure altitude, provided con-tinued flight will not exceed this altitude.
