FIG ENR 1.1.25
NAS Stage A Controller’s View Plan Display
NOTE.
FIG ENR 1.1.25 illustrates the controller’s radar scope (PVD) when operating in the full automation (RDP) mode, which is normally 20 hours per day. When not in automation mode, the display is similar to the broadband mode shown in the ARTS III Radar Scope (FIG ENR 1.1.24). Certain ARTCCs outside the contiguous U.S. also operate in “broadband” mode.
EXAMPLE. Target symbols:
1.
Uncorrelated primary radar target [] [+]
2.
Correlated primary radar target [ ]
See note below.
3.
Uncorrelated beacon target [ / ]
4.
Correlated beacon target [ \ ]
5.
Identing beacon target []
Note: in Number 2 correlated means the association of radar data with the computer projected track of an identified aircraft.
Position symbols:
6.
Free track (no flight plan tracking) [ ]
7.
Flat track (flight plan tracking) [.]
8.
Coast (beacon target lost) [#]
9.
Present position hold [ ]
Data block information:
10. Aircraft ident
See note below.
11. Assigned altitude FL 280, Mode C altitude same or within 200’ of assigned altitude.
See note below.
12. Computer ID #191, handoff is to sector 33 (0.33 would mean handoff accepted)
See note below.
13.
Assigned altitude 17,000’, aircraft is climbing, Mode C readout was 14,300 when last beacon interrogation was received.
14.
Leader line connecting target symbol and data block.
15.
Track velocity and direction vector line (projected ahead of target)
16.
Assigned altitude 7,000, aircraft is descending, last Mode C readout (or last reported altitude) was 100’ above FL 230
17.
Transponder code shows in full data block only when different than assigned code
18.
Aircraft is 300’ above assigned altitude
19.
Reported altitude (no Mode C readout) same as assigned. (An “n” would indicate no reported altitude.)
20.
Transponder set on emergency Code 7700. (EMRG flashes to attract attention.)
21.
Transponder Code 1200 (VFR) with no Mode C
22.
Code 1200 (VFR) with Mode C and last altitude readout
23.
Transponder set on radio failure Code 7600 (RDOF flashes)
24.
Computer ID #228, CST indicates target is in coast status
25.
Assigned altitude FL 290, transponder code (these two items constitute a “limited data block”)
Note: numbers 10, 11, and 12 constitute a “full data block”
Other symbols:
26.
Navigational aid
27.
Airway or jet route

37.5 Airport Surface Detection Equipment . Model X (ASDE.X)
37.5.1 The Airport Surface Detection Equipment . Model X (ASDE.X) is a multi.sensor surface surveillance system the FAA is acquiring for airports in the United States. This system will provide high resolution, short.range, clutter free surveillance information about aircraft and vehicles, both moving and fixed, located on or near the surface of the airport’s runways and taxiways under all weather and visibility conditions. The system consists of:
37.5.1.1 A Primary Radar System. ASDE.X system coverage includes the airport surface and the airspace up to 200 feet above the surface. Typically located on the control tower or other strategic location on the airport, the Primary Radar antenna is able to detect and display aircraft that are not equipped with or have malfunctioning transponders.
37.5.1.2 Interfaces. ASDE.X contains an automa-tion interface for flight identification via all automation platforms and interfaces with the terminal radar for position information.
