Q

A target is considered to be paired when…

A

The computer correlates the predicted position, speed, and heading with the actual radar return using flight plan information

Q

What is the velocity vector?

A
  • Represents the distance and the direction the aircraft will travel in selected minutes based on the average of the most recent radar position updates.
  • It is based on the computer generated ground speed and track.

Q

What is meant by “paired” and “unpaired” target symbols?

A

• Paired-the computer correlates the predicted position, speed, and heading with the actual radar return using flight plan information. • Unpaired- the computer has no stored flight plan information and issuing radar data only.

Q

What does the accent symbol in field A mean?

Q

Field C consists of…

A
  • Four character positions
  • C1-C3 include mode C or controller entered reported altitude, upper altitude of a block altitude, XXX is mode C is corrupt or lost
  • C4… # for when an aircraft is not responding with mode C and controller altitude does not equal the single assigned altitude (altitude information in field C will not automatically update unless Mode C is reestablished) Also when associated with a block altitude it means the aircraft is within controller-entered block altitude
  • C4… X for exceptional vertical rate indicator or EVRI (when the aircraft is climbing/descending at a rate greater than the computer adapted aircraft performance profile) (the system will not use this mode C for safety alert processing, the system reverts to a normal rate that is appropriate for the type aircraft. This is also true for RA conflict probe).

Q

What does field D consist of?

A
  • Four alphanumeric
  • D1- R if you do not have track control
  • D2-D4 – contain the CID
23
Q

What does track control mean?

A

Allows you to make changes to the aircraft database information

24
Q

What does field E consist of?

A
  • 5 characters that contain ground speed (displayed if no other information is displayed and on an equal time sharing basis of an additional item becomes eligible for display) Not displayed if more than one item becomes eligible for display
  • Special condition information relative to the status of the aircraft (displayed on an equal time sharing basis and blinks for various time periods depending on the content)
  • E1 character is adapted in some facilities to display a single letter reflecting aircraft destination
25
Q

Define EMRG, RDOF, FAIL, OLD, MISM, FRZN, HOLD, CST, NONE, 253, 3214

A

• Squawking Emergency • Radio Failure • Attempted handoff of FDB to another facility has failed • Updated data is not being received • Mismatch between two facilities track position • Controller-entered message that indicates the flights position is not being updated

26
Q

What is in Field F?

A

• Variable data field with nine character positions located in the fourth line of the FDB • Aircraft Type/Equipment • Destination • Heading/Speed/Both • Free Form text

27
Q

How do you input heading, speed, and deviations into field F?

A

• H140, PH, H090/FSM, PH/J43, H310/J80, 320/v187, PH/CHA • S300, S230+, M78, M80+, M82- • DW, DR, DS, D10L, D20E, D25R, D10N • RQ070, RQ130 • RQ/SGF, RQ/WENDY

28
Q

Do you need to verbally coordinate when using H, PH, S, or D, RQ, RQ/?

A

No, may be used with out

29
Q

When would you be able to omit an H?

A

Due to character limitations if it does not result in a misunderstanding

30
Q

When is the Heading/Speed/Free Form (HSF) Display/Suppress Indicator displayed?

A

If the heading, speed, or free form text is displayable (stored)

31
Q

The fourth line of the data block includes what?

A

Free form text entered by the controller

32
Q

What are the different kinds of data blocks and what do they display?

A

• Alternate Data block- Call sign, Assigned altitude, mode C altitude, position symbol, leader line, vector line, and displays in the same intensity as FDB • Enhanced Limited Data block- call sign, assigned altitude, mode C, displays at the same intensity as LDB and always appears east of the target • Paired Limited Data block- call sign, mode C altitude, displays at same intensity as ELDB, always appears east of target • Unpaired Limited Data block- beacon code and mode C if available for untracked aircraft, displays same intensity as LDB, always appears east of target, does not show code for VFR just a V for 1200, only data block that does not contain a call sign, Mode C Intruder unpaired limited data blocks occur for untracked aircraft (target symbol is an I)

33
