Answer 4

10 miles; 5 miles; 3 miles

Question 5

When transitioning from terminal to en route

Answer 5

3 miles increasing to 5 miles+ provided:

• a/c are diverging, lead a/c is faster
• separation is constant or increasing
• 5 mi or other appropriate separation is obtained within the first center sector
• procedure is covered by LOA

Question 6

A388/An225 separation

Answer 6

• Behind A388: 5 miles
• A380/An225 operating at or below 250 kts/below FL240: 8 miles
• transitioning to terminal: 8 miles +
• no visual separation

Question 7

A388/An225 use of word super

Answer 7

immediately after the a/c call sign in communications with a terminal facility , when center acts as approach control, traffic advisories

Question 8

use Wake turbulence separation when an a/c is operating..

Answer 8

directly behind and less than 1000 ft below or following an a/c conducting an instrument approach

Question 9

wake turbulence separation

Answer 9

heavy behind heavy: 4 miles
large/heavy behind B757: 4 miles
small behind B757: 5 miles
small/large behind a heavy: 5 miles

Question 10

separate a/c from obstructions by

Answer 10

5 miles

Question 11

separate a/c from adjacent airspace

Answer 11

below FL600: radar 2.5 miles, non radar 5 miles

FL 600 and above: radar 5 miles, non radar 10 miles

Question 12

separate a/c from special use airspace and air traffic control assigned airspace involving a/c operations

Answer 12

Lateral: below FL600 3 miles, FL 600 and above 6 miles
Vertical: FL290 and below 500 ft, above FL290 1000 ft

Question 13

SUA or ATCAA for security reasons or hazardous activities not involving a/c operations

Answer 13

vector a/c to avoid airspace

Question 14

separation for formation flights

Answer 14

a/c from standard formation flight: add 1 mile
two standard formation flights from each other: add 2 mi
a/c from nonstandard formation flight: apply appropriate minima to perimeter of airspace around formation or outermost a/c; assign beacon code to each a/c in formation or first and last a/c in trail

Question 15

Give priority to separating a/c over issuing safety alerts. T/F

Answer 15

False; give equal priority to issuing safety alerts and separating a/c

Question 16

Once observed and recognized, issue a safety alert when a/c is in a position which places it in unsafe proximity to

Answer 16

terrain, obstructions or other a/c

Question 17

conflict alert (CA)

Answer 17

alert radar controllers to existing or pending situations between tracked targets (known IFR OR VFR a/c) that require immediate attention/action

Question 18

mode c intruder (MCI) alert

Answer 18

alert radar controllers to existing or pending situations between a tracked target (known IFR or VFR a/c) and an untracked target (unknown IFR or VFR a/c) that require immediate attention/action

Question 19

Issue a traffic alert immediately when a known conflict with other a/c exists and …

Answer 19

• offer alternate course of action, if feasible

- end transmission with the word immediately

Question 20

Conflict alert may be suppressed/restored by the controller

Answer 20

• constitutes controller acknowledgement

- indicates appropriate action has been or will be taken

Question 21

What are some conditions that might affect whether a controller will recognize a safety alert situation?

Answer 21

• workload
• traffic volume
• quality/limitations of radar
• available lead time to react

Question 22

altitude readout is

Answer 22

an a/c altitude, transmitted via the mode c transponder feature

Question 23

ensure validity of each a/c after…

Answer 23

• accepting an interfacility handoff
• initial track start
• track start from coast/suspend tabular list
• missing or unreasonable mode c readouts

Question 24

Mode C readout must be revalidated after the X from EVRI…

Answer 24

is no longer displayed in the data block

Question 25

consider readout valid when:

Answer 25

• varies less than 300 ft from reported altitude
• receive a continuous readout from a/c on the airport and the readout varies less than 300 ft from field elevation
• verbal coordination with another facility with validated altitude information shows exact correlation between your data block and theirs

Question 26

When you observe an invalid mode c readout below FL180

Answer 26

• issue the correct altimeter setting and request pilot to verify altitude
• if mode c readout is still invalid: instruct pilot to turn off altitude reporting part of transponder and include reason; notify area supervisor of the a/c call sign

Question 27

When you observe an invalid mode c readout at or above FL180

Answer 27

inform supervisor and apreq with next sector

Question 28

Request pilot to verify assigned altitude on initial contact unless

Answer 28

• pilot states assigned altitude
• you assign a new altitude to a climbing/descending a/c
• mode c readout is valid and indicates that the a/c is at assigned altitude

Question 29

inform a/c to turn automatic altitude reporting feature on/off by:

Answer 29

• squawk altitude

- stop altitude squawk
