Answer 4

CST or FRZN

Question 5

What is radar separation?

Answer 5

• At or above FL600- 10 miles
• Below FL600 5 miles
• Below FL180 and within 40 miles of the antenna-3 miles if specified in FD

Question 6

Separation required when transitioning from terminal to enroute?

Answer 6

3 miles increasing to 5 miles or greater provided: diverging or lead is faster, sep is constant or increasing, 5 miles or other appropriate separation is obtained within the first center sector, procedure is covered in an LOA and limited to specific routes and or sector positions

Question 7

Separation with the A388 and B748

Answer 7

5 miles behind, 10 when transitioning to terminal, no visual
separation (include the expression SUPER immediately after the a/c call sign in communications with terminal facility or traffic advisories

Question 8

Wake turbulence.

Answer 8

• Directly behind and less than 1,000 ft below or following an aircraft conducting an instrument apch (and takes precedence over 3 mile separation)
• Heavy behind heavy (4)
• Large/heavy behind a B757 (4)
• Small behind a B757 (5)
• Small/large behind heavy (5)

Question 9

Separate aircraft from obstructions by…

Answer 9

5 miles

Question 10

Separate aircraft from adjacent airspace by:

Answer 10

• Below FL600- 2.5 radar controller/5 non radar controlled

* At and above FL600-5 radar controller/10 non radar controlled

Question 11

Separate aircraft from SUA and ATCAA by:

Answer 11

• Involving aircraft operationso
Below FL600- 3 miles
o At and above FL600-6 miles
o At and Below FL290- 500 ft
o Above FL290 1,000
• Not involving aircraft operationso
Aircraft must just avoid airspace

Question 12

Formations flight separation.

Answer 12

• Standard-1 mile
• Two flights- 2 miles
• Non standard- apply appropriate minima from the parameter of the airspace encompassing the flight from the outermost aircraft (beacon codes if need be)

Question 13

Give equal priority to…

Answer 13

Separating aircraft and issuing safety alerts (perform the action most critical from a safety standpoint)

Question 14

Once observed and recognized, issue a safety alert when an aircraft is…

Answer 14

In a position which places it in unsafe proximity to terrain,
obstructions, or other aircraft

Question 15

Do not assume that because another controller has responsibility for the aircraft that the unsafe situation has been observed and that the safety alert has been issued….

Answer 15

Inform the appropriate controller (coordination is not required when immediate action is dictated

Question 16

When can you discontinue further alerts?

Answer 16

When the pilot informs you that action is being taken to resolve the unsafe situation

Question 17

What are the origins of alerts?

Answer 17

En route minimum safe altitude warning, automatic altitude

readouts, conflict alert/mode C intruder, pilot reports

Question 18

What is a conflict alert?

Answer 18

A function of certain air traffic control automated systems
designed to alert radar controllers to existing or pending
situations between tracked targets (known IFR and VFR) that require immediate attention/action

Question 19

Define mode C intruder.

Answer 19

A function of certain air traffic control automated systems
designed to alert radar controllers to existing or pending
situations between a tracked target (known IFR or VFR) that
require immediate attention/action

Question 20

When would you issue a traffic alert and what would you issue?

Answer 20

• Immediately when a known conflict with other aircraft exists
• Offer alternate course of action if feasible and end the transition with the word immediately

Question 21

When will a full data block flash?

Answer 21

When targets are within a predetermined parameter of each other and less than minimum vertical separation exists (alert is based on mode C readout or controller reported altitude therefore timely altitude updates are imperative)

Question 22

Why should you not rely totally on computerized alert?

Answer 22

May activate late or wont activate unless altitude is known

Question 23

What does it mean when a controller suppressed/restored the alert?

Answer 23

Constitutes controller acknowledgment and indicates appropriate action has been or will be taken

Question 24

Define altitude readout.

Answer 24

An aircrafts altitude transmitted via the mode C transponder feature that is visually displayed in 100ft increments on a radar display having readout capabilities

Question 25

When must you ensure validity of each aircraft?

Answer 25

After: accepting an inter-facility handoff, initial track start, track start from a coast/suspended tabular list, missing or unreasonable mode C readouts

Question 26

Whose responsibility is validating mode C?

Answer 26

Shared responsibility of the radar team

Question 27

Can a previously validated mode C be used for separation when the exceptional rate indicator “X” is displayed?

Answer 27

Yes

Question 28

When is a readout considered valid?

Answer 28

Varies less than 300 ft from pilot reported altitude or you receive a continuous readout from an aircraft on the airport and there read out varies by less than 300 ft from the airport elevations or verbal coordination with another facility with validated altitude information shows exact correlation between you data block and theirs

Question 29

What do you do if you are unable to validate the read out?

Answer 29

Do not use mode C information for separation

Question 30

What do you do when you observe an invalid mode C readout below FL180?

Answer 30

* Instruct the pilot to turn off altitude reporting part of transponder and include the reason * Notify area supervisor-in-charge of the aircraft callsign

Question 31

What should be done before allowing an aircraft who has lost altitude reporting capability into another controllers class A airspace?

Answer 31

Verbal approval required

Question 32

When do you not have to request a pilot to confirm assigned altitude on initial contact?

Answer 32

Pilot states assigned altitude or you assign a new altitude to a climbing or descending aircraft, or mode C readout is valid and indicates that the aircraft is established at the assigned altitude

Question 33

How do you inform an aircraft to turn the automatic altitude reporting feature on or off?

Answer 33

SQUAWK ALTITUDE or STOP SQUAWK ALTITUDE

Question 34

Do all aircraft have the ability to disengage altitude squawk independently from beacon code squawk?

Answer 34

No some are controlled by the same switch and you may loose beacon code
